Data Visualizations using Tableau

It’s so simple, a Data Scientist can do this.

This page provides an enhanced / deeper sequence to presenting Tableau based on a hands-on approach with less hype and marketing generalities.

• tableau.com/learn/starter-kit provides a learning sequence with clickable links to materials.

Tableau enables everyone to gain insights from raw data by providing a drag-and-drop UI working on data in many formats. In the biz it’s called a visual Data Analytics platform.

Alternatives to Advanced Data Analytics

Tableau’s promo video says:

• [0:30] “People build dashboards and applications like these, drag and drop, at up to 10 times the speed of a traditional business intelligence system”.

By “traditional,” it means:

• Microsoft Power BI, Power Pivot, and Power View in Excel 2013, see “Difference between Microsoft BI and Tableau” and “Better Together”.

• IBM Cognos Insight
• MicroStrategy Visual Insight
• Oracle Exalytics appliance
• SAS Visual Analytics Explorer
• SAP Lumira ($995/user from SAP store)
• SAP Visual Intelligence
• TIBCO Spotfire
• Qlik Sense
• http://www.xdat.org/
• Information Builders
  
  

New technology vendors include public cloud services vendors:

• Amazon QuickSight
• Google Looker
• Alibaba
  
  

Gartner’s Feb. 2021 Magic Quadrant has Tableau trailing Microsoft in both Strategy and “Ability to Execute”.

Gartner notes “Tableau does not directly compete with other vendors with a strategy for being a broad BI platform offering. Tableau complements fully functional enterprise BI platforms that lack ADV capabilities.” That is why This Forrester report (although rather dated from 2012) has Tableau lagging on the horizontal strategy dimension:

The Gartner Magic Quadrant report in Feburary 2017 put Tableau almost neck-to-neck with Microsoft on the “ABILITY TO EXECUTE” scale:

In the previous year’s Magic Quadrant of Feb. 2016, Gartner’s kept Tableau at the top for Execution even though it downgraded most other vendors on that scale while it acknowledged Microsoft’s fast rise to be the leader in Completeness of Vision:

The Gartner Magic Quadrant report in 2015 also put Tableau above other vendors on their “ABILITY TO EXECUTE” scale.

Another alternative are JavaScript libraries developers incorporate into their home-grown visualization solutions:

• D3.js

• nvd3.org/

Tableau focuses on presentation rather than both presentation and statistical calculations by software such as:

• Matlab
• R, an open-source (free) software

4D Visualization

Since 2007 at http://www.gapminder.org/videos/ Hans Roling, a professor of health statistics in Sweden, is an internet legend for his “Joy of Stats” video shown on BBC Nov 10, 2010 and Ted Talks. In them he shows his Gapminder web app which presents multiple dimensions dynamically over time (nearly 300).

Jeffrey Shaffer created a time lapse video of his viz showing a trail of dots which grow in size and get darker over time (as the legend notes):

Here, different colors represent different countries, with the United States in red. Most other countries saw a decrease in fertility rate over time while life expectantcy increased.

Within the wonderful Tableau gallery Andy Cotgreave (@acotgreave, now Technical Evangelist at Tableau) built over the years is this re-creation of Gapminder:

Andy explained in 2010 how he created the above using Tableau Trendalyzer v6. Download his viz from the Tableau Public website to manipulate using the Tableau Public client installed on your laptop.

This chart is an example of traits excellent visualization software possesses:

• Dynamic data - update visualizations (in “live mode”) as data changes in sources such as databases.

• Visual querying - change the query by selecting or clicking on a portion of the graph or chart (to drill down, for example).

• Linked multi-dimensional visualization - selections made in one chart are reflected as you navigate into other charts.

• Animation -

PROTIP: Dynamic (movie mode) is available only within the Tableau Public client, not when viewed on websites (as of 2016-01-05).

• Personalization - give power users an in-depth view and newbies a simpler view, and also control access to data based on user- and role-based access privileges.

• Actionable alerts - thresholds and parameters that trigger messages whether you’re interacting with reports or not.

Tableau’s Architectural Components

Several editions of Tableau client programs can be installed on Windows and Mac laptops.

The licensed Desktop edition can read more types of data sources.

The Tableau Public website (http://public.tableausoftware.com) provides a gallery for showing workbooks created using the Public edition of client software. Tableau limits public workbooks up to 1 GB large containing up to 100,000 data rows.

Tableau also does not allow the Public client to store files locally on a laptop.

PROTIP: Use the Public client when you have reliable public network access.

The Desktop edition can retrieve workbooks from the Public website. However, workbooks created on Tableau Desktop cannot be published to Tableau Public.

Private workbooks can be shared on a Tableau Server or in the Online service Tableau runs. A web app accessed using an internet browser is used to administer users on those servers.

Tableau’s native mobile apps on both Android and iPads make use of REST APIs that other servers can use to access data.

QUESTION: Can Mobile clients access Tableau Public?

https://gallery.alteryx.com/#! is viewed using a Alteryx Designer Windows client.

The Tableau Reader client can read (but not save) packaged workbooks.

Prices are subject to change at any time, and subject to negotiation. At time of writing, Tableau Desktop costs $1999. Tableau Server is around $1000 per user or ~$200K for an unlimited user license. Tableau Cloud costs $500/per user per year. The Tableau Cloud plan includes 100 GB of storage. I do not know the storage add-on costs for groups wanting more than 100 GB.

Tableau makes use of HTML5 within internet browsers. It’s unlike Microsoft Power Viewer, which depends upon installation of Silverlight and thus not mobile device friendly.

Mobile App

Tableau offers native mobile apps on both Android and iPads.

• https://play.google.com/store/apps/details?id=com.Tableau.TableauApp&hl=en
• https://itunes.apple.com/us/app/tableau-mobile/id434633927?mt=8

The apps reskins the internet browser, which can also be used to access workbooks.

1. Click Sign In.
2. For Sever Name, to use Tableau Public cloud, enter public.tableausoftware.com (without the https:// prefix). Ignore the “Tableau Online”.
3. Click the orange Connect that appears to the right.

Client Programs Installation

The different Tableau clients are downloaded from separate URLs.

Tableau Desktop Personal and Pro editions are licensed at $999 and $1999 per year to access a wide range of data sources.

• http://www.tableau.com/products/reader

QUESTION: Why is the Reader larger than others when it has less capability?

QUESTION: You don’t need to install Reader if you have Desktop installed?

The Server Download from here only runs within Windows (32 or 64-bit) and uses Active Directory Authentication.

There are several ways to open a Tableau client program:

1. Open Excel Samples from Local Data Folder.
2. Open a Tableau Client Program if you have your own file.
3. Load CSV from Public Sample Data Sets.

Open Excel Samples from Local Data Folder

1. On a Mac, open a new Finder window.

2. Within your user’s Documents folder, scroll to click on the My Tableau Repository folder created during client installation.

3. Click to drill into the Datasources folder.

   NOTE: The Tableau client remembers (encrypted) credentials to external data sources (such as Google Analytics) in this folder (as files with extension .tde).

4. Click on a version number of the Tableau client installed (9.2).

   There is a separate folder for each version of Tableau (9.2, 9.0, etc.) because data structures often change with each new version.

5. Click on a locale (en_US_US).

   Tableau clients 9.0 come with an Excel (.xls) file Sample - Superstore.xls. Notice it’s 3.4 MB.

6. Optionally, click on that file to open it within Excel (if you have Microsoft Office installed).

   Within Excel, at the lower left corner, notice there are 3 tabs (worksheets) named Orders, Returns, People.

7. Switch back to Finder. To open .xls files from the Finder, control-click on the xls file and select Open With > Other …, select Tableau.
8. For Enable: select All Applications.

9. Select Tableau and click OK to view in Tableau client Data Connection window:

   

   You can also get here by clicking “Excel” in Tableau’s Connect menu.

10. Click the red x at the upper left corner to close the program.

Predicting Diamond Prices

In this initial project, students use results from a predictive model to make a recommendation on how much a jewelry company should bid for diamonds.

Multi-variate Linear Regression

To work through how a homegoods manufacturer can predict expected profits from a catalog launch, students build a linear regression model to provide results and a recommendation.

1. Download the sample data .csv files.

2. In Finder, double-click on the diamonds.csv file to open it in Excel:

   The training set contains historical data where the outcome is already known.

   The sample diamonds.csv has 50,000 rows.

   Outcome values are in the target variable (price).

   Excel needs all variables together, so:

3. Select the letter above the “caret” column to select the whole column.
4. Press Ctrl+X to cut. Click on the column heading to the right of the “price” column.

5. Repeat for the “clarity_ord” and “cut_ord” columns.

6. In Excel Data tab, Click on Data Analysis.
7. If you don’t see “Data Analysis”, enable Analysis Toolpack. This only needs to be done once.

8. Select Regression and OK.

   Conditions of attributes are in the predictor variables, also called dependent variables or (in Excel), Y Range.

9. Click the red arrow icon for Y Range.
10. Check “Labels”

11. Click in row 1 “price”. Press Command-shift-down to select the whole column

    $H$1:$H$50001

12. Click the icon to collapse the pop-up.

13. Press Enter.

    $I$1:$K$50001

14. Click the icon to Output range.
15. Cick cell M1.

16. Press Enter to accept it.

17. Click OK.

18. Variables with P-values (Prediction-values) beyond .15 should not be used.

    Regression equation models enable predictions to be made based on attribute values.

The test dataset (new-diamonds.csv) contains new instances.

Select the Location of a New Pet Store

Students use data preparation techniques to build a robust analytic dataset and use it to build a predictive model to select the best location for a pet store chain.

Data Transformation using Alteryx

NOTE: In 2015, Tableau did not have an ETL tool. Tableau add-in Alteryx for groups wanting true self-service ETL like Microsoft Power Query M scripting (formerly called Data Explorer) that does pivot/unpivot, joining, filtering, deduplicating, grouping, splitting, and transforms.

http://kb.tableausoftware.com/articles/knowledgebase/preparing-excel-files-analysis has some basic pivoting and cleansing features.

Alteryx performs Data blending of multiple and disparate data sources

Alteryx does predictive and spatial analytics with no coding required

Alteryx makes re-useable, modifiable workflows and direct updates to Tableau workbooks.

Date Adjustments in Excel

It may be easier to adjust data within Excel before Tableau uses the file, which is the number of seconds from 1970 (not the number since 1970 as Unix uses).

Tableau doesn’t read TIME according to (as of Oct 12, 2015) https://community.tableau.com/ideas/3315 and https://community.tableau.com/ideas/1054

• http://kb.tableau.com/articles/knowledgebase/supported-date-formats
• http://kb.tableau.com/articles/knowledgebase/fixing-date-fields
• http://kb.tableau.com/articles/knowledgebase/understanding-the-dateparse-function

Where A2 in the sample is replaced with wherever cell contains a date Excel recognizes, to convert the text “2016-01-12” to the internal date number of 42381.00:

 =DATEVALUE(LEFT(A2,4)&"-"&MID(A2,6,2)&"-"&MID(A2,9,2))+(NUMBERVALUE(MID(A2,12,2))/24)+(NUMBERVALUE(MID(A2,15,2))/1440)

Within Excel, hours and minutes are the decimals of a floating point number, such as .88 when the text equivalent is “21:40” on a 24 hour clock:

 =(NUMBERVALUE(MID(A2,12,2))/24)

To convert 40 minutes into the hour, divide the number of minutes in a day (24 * 60 = 1440):

 =(NUMBERVALUE(MID(A2,12,2))/24)+(NUMBERVALUE(MID(A2,15,2))/1440)

The number for minutes would not be more than 1/24 or 0.041666667.

To convert UTC/GMT times to local time that is -8 hours for Pacific Standard Time (Seattle):

 =A2-TIME(8,0,0)

NOTE UTC/GMT times are never adjusted for Daylight Savings, so the number of hours difference changes during the year. During the summer it’s 7 hours. See http://www.timeanddate.com/worldclock/converted.html?iso=20160114T00&p1=0&p2=234

http://www.cpearson.com/excel/TimeZoneAndDaylightTime.aspx The LocalOffsetFromGMT() function

To zero-fill leading zeroes:

 =TEXT(A2,"000")

Reshaper Add-in

Tableau no longer maintains its add-in to prepare data in Excel to for use by Tableau.

File tableau_data_tool.zip downloaded from the website expands to Setup-Tableau-Add-In-7.0.exe. Thus it’s only for the Windows edition of Office (not Mac).

Save and Close Client Program

After you click the red x at the upper left corner of the window, a pop-up appears if data was changed. A file name is suggested.

1. Change the name from Book2 or whatever is auto-assigned to something else.

   

If you change the default folder from Workbook (.twb) to Packaged workbook, data files and dashboard specifications will be packaged into a single .twbx file.

Load Local Sample Dashboards

With Tableau client UI program open:

1. Click menu Help

   Sample Workbooks. These were installed among binary files:

   • Superstore contains a forecast dashboard based on data connected live. This is different than what is presented in the Getting Started videos.

   • Regional

   • World Indicators (contains several dashboards referenced from a Story)

2. Close the program.

Rename & Open Tableau Client Program

After installation on a Mac, open a Tableu client:

1. Open a Mac Finder window by holding down the command and pressing Tab until the Finder icon is highlighted.

   

2. Pull down the Finder Go menu for Applications or press Shift+command+A.

   The Tableau Desktop program is named simply “Tableau”.

   NOTE: If a second version of the same program was installed, it would be automatically named “Tableau 2”.

3. PROTIP: Change the name to include version (such as 9.2.0 or 9.0.4, etc.).

4. Double-Click on the Tableau program to start it.

   Return to the Start page by pressing command+2 or menu File.

5. On a Mac, click Tableau and About Tableau.

   The top of the pop-up lists the specific version installed, such as “9.2.0 (9200.15.1201.0018) 64-bit”. Provide this to Tableau Support.

6. Click the red x at the upper left of the window to close the pop-up.

   Notice the Tableau Desktop edition has “Server” in its menu:

   

   EXTRA: More than one instance of the Tableau client can be running at the same time.

   

   The above is from the Pro version, which has many drivers which connect to more data sources under the Connect section.

7. Click Statistical Files to accesses files from SAS and IBM SPSS:

   

   NOTE: Not listed are MathCAD nor Microstrategy, SAP HANA, and other BI tools.

8. Select All files

   

File Types

As explained here:

.csv is a Comma Separated Value (character delimited) text format that Excel and many other programs open.

.xls is a Microsoft Office Excel 1998+ format.

.xlsx is a Microsoft Office Excel 2007+ format.

.txt files are also considered among “Other files” that Tableau opens.

.tds data source files (as explained here) are like shortcuts containing information needed to just connect to the data sources, such as data source type, location, and custom fields.

.tde extract files (explained here) are a local copy of an entire data source (or its subset) created programmatically using Tableau Extract API.

.tdsx Packaged Data Source files contains all the information in the Data Source (.tds) file as well as any local file data sources (Excel, Access, text, and extracts). Packaged means a single zipped file for easier sharing a data source with people who may not have access to the original data that is stored locally on your computer.

.twb is the native workbook. It does not contain any data, which is why a packaged workbook is needed.

.twbx packaged workbook files (as explained here) contain one or more worksheets, plus zero or more dashboards and stories. These files are what is transferred to and from Tableau servers.

CAUTION: None of the above formats are encrypted with any data security.

.ttde are Shadow Extract files used for caching speed within clients and not directly referenced by users. Five of these files are stored within a Shadow Extract folder.

http://onlinehelp.tableau.com/v9.2/public/online/mac/en-us/help.html#upgrading_connection.html

1. PROTIP: You may want to create a separate folder to store all Excel data files locally in the same Excel folder. Store all Microsoft Office Access files in an Access folder.

Load CSV from Public Sample Data Sets

1. Use an internet browser (Firefox) to view where Tableau makes public datasets available.

2. Scroll to The 2014 Inc. 5000.

3. Click on Dataset (csv) (comma separated values) link.

4. Click the blue icon to the right of the Open With selection.

5. If Tableau (for the version you’re using) is not already listed, click Other and select it.

   

6. Click OK to save. The file would, by default, be saved to your user’s Download folder anyway.

   

   CAUTION: All other openable files (.csv, .txt, .xls, etc.) are also shown.

7. Click Extract.

   

   This appears.

   

8. Click Save.

9. [3:04] Click Sheet 1 at the bottom of the window to create a chart based on the data.

10. Close the program.

11. PROTIP: In Finder, navigate to the Downloads folder and delete the .csv file. This clears off clutter.

Public Datasets

The Client Pro certification exam uses the FAA Wildlife Strike Database

Tableau provides a Solution Guide which shows constructed viz to answer the certification questions:

* Do some species have more strikes in some months over others? 
* Are there any species appearing in the top that are surprising? 
* Calculate the strike rate (number of strikes divided by the number of total flights) to see if the rate of wildlife strikes is increasing or decreasing over time.

* Where are these strikes most likely to occur?
* Are there certain months when wildlife strikes become more likely?
* Have the number of strikes per year been changing over time?
* Does the number of flights have any effect on seasonal trends?
* Combine views into a dashboard allowing users to explore the data themselves.

Note that you should not be confined to a specific number of species per month and should use a parameter to make a dynamic Top N.

Get the sample dataset:

1. Scroll to the bottom of the page to
2. Click <a target=”_blank” href=”http://wildlife.faa.gov/downloads/wildlife.zip</a> “FAA Wildlife Strike Database”</a> link without specifying any filters to download wildlife.zip.
3. Unzip the file for a folder named “wildlife”.
4. Drill into the folder.
5. Double-click on “wildlife.accdb” to open it using Microsoft Office Access.
6. The read-me.xls file in the folder is the same as the one obtained by clicking “total of 94 fields of data” for the fieldlist.xls. It contains a description of Column Names, Engine Codes, Aircraft Type, Engine Position.

If you are using a Mac, because Microsft Office for Mac 2011/2016 does not include Access, you’ll need to consider several options for reading the .accdb Microsoft Access database file.

• The simplest option is to temporarily use a Windows machine or a virtual Windows machine containing MS Office Access – if they are already installed and available for use.

• The $39.99 ODBC read-only driver for Microsoft Access from Actual Technologies enables Excel 2011 for Mac to execute SQL queries using Microsoft Query (comes with Microsoft Office) or a PivotTable.

  • http://mthomas.co.uk/5-ways-to-access-access-on-a-mac/ notes that utilities such as http://mdbtocsv.codeplex.com support only older .MDB formats, not the .accdb format.

• The $5.99 MDB Tool - For Microsoft Access by Hankinsoft Development Inc from Apple iTunes only handles databases in 2007 format, not 2010/2013 format.

• http://serversideguy.com/2014/02/05/import-microsoft-access-accdb-file-to-ms-sql-server/

Public Galleries

I think infographics are a form of art like paintings and sculptures. And beauty is in the eyes of the beholder. But clean looks are now preferred as being more modern.

PROTIP: To be good at creating your own, first get to know what others have done, starting from being able to name the different chart types.

1. Save the URL and click links to save workbooks to presentations that you might want to use.

   WARNING: Most data in examples are several years out of date.

These galleries show why Tableau is among the most capable and popular of visualization software, providing a rich variety of chart types to make sense of data.

Tableau’s Gallery has URLs that are different with each new build of their website.

NOTICE: The permalink for the current version is near the bottom of each chart.

https://public.tableau.com/ is a social sharing site for people to show and blog about their visualizations of public data sets. This is much like what Adobe offers.

“VIZ of the day/week” from the Tableau Public sharing website is highlighted on the right side of the opening landing page on Tableau clients.

https://public.tableau.com/s/resources announce monthly webinars and provides free on-line training videos also published under Tableau Smith on YouTube, which has more videos than on the website.

QUESTION: How to describe changes over time? Videos instead of text blogs?

Vizzes by bloggers can be published on other sites, such as:

• http://blog.numbersbox.com/2015/06/global-obesity-were-getting-bigger.html

Radar charts

Radar charts are great for visually identifying which of several dimensions are possessed by specific sub-populations shown using cicle-ish lines in the middle.

In this example, one can see that wines rated good and excellent (in dark red) have high alcohol while wines rated as poor (shown in thick black line) have low alcohol.

Geospatial Maps

Geographic maps make use of geocodes that come with Tableau.

• Choropleth maps color land forms to differentiate values.
• Geo bubble charts overlay different size dots.

Tableau allows the use of WMS servers, GIS sources and custom shapes.

Getting Started video content

PROTIP: Things happen fast on this video. So most beginners will need to pause frequently and watch several times. The web video presentation automatically jumps back to the beginning after long pauses, and doesn’t show the entire screen until it’s maximized. Annoying. So use the link to save the MP4 video file so you can download it for viewing offline.

1. Click on the video and register.
2. Scroll to the MP4 link to the video that appears after registration.

Tableau’s VizQL is a visual query language which translates drag-and-drop actions into data queries expressed visually.

Joins and Data Splits

The sample Excel workbook contains Sheets named Orders, People, and Returns. “Users” are used in previous versions of this file.

1. Drag one of the Sheets (Orders) to the canvas pane.

   Version 9+ automatically recognizes a “union (add rows)” drop target that concatenates multiple files containing the same headings.

   Version 9+ has an Excel cleaning data interpreter feature that automatically recognizes and stiches together subtables into a single data source.

2. Drag another Sheet (Returns) to the canvas.

   Tableau automatically suggests a join type:

   

3. If a column contains multiple fields, split them into sub-columns:

   

4. Because data is now loaded within Tableau, hover over a heading to Rename the heading to “Distribution Center”.

5. Delete split sub-columns not needed.

6. Click on the data type under the heading name to change it.

   

   NOTE: You can later return to this by clicking tab “Data Source” at the lower left of the screen.

7. [3:06] Click on Sheet1 at the bottom set of tabs.

   NOTE: Each sheet is also called a view.

   You are asked to save the data.

EXTRA: [4:04] into video http://www.tableau.com/learn/tutorials/on-demand/getting-started-data shows linkage to add columns from another data source (Returns table) and inner vs left join.

Save Live or Extract Offline

1. [02:42] Specify a Live connection to dynamically retrieve fast-changing data or import a static Extract for offline usage.

   

CAUTION: Tableau does not save to disk automatically every few minutes (like Microsoft Office does).

If you save the file, the program suggests a name such as “Orders+ (Global Superstore)”.

PROTIP: Add a version number to the file name if you would like to be able to go back archival generations.

Shelves for Dimensions and Metrics

One of the amazing features of Tableau is it enables users to create sophisticated tables and charts just by dragging and dropping, then clicking around. (By contrast, some coding declarative statements used to define visualizations in Kibana.)

Each dimension element dragged to the Columns shelf defines a level in the hierarchy of columns.

1. [3:21] Drag from among Dimensions Category and drop within the Rows shelf.

   The three category values are shown in a table.

   “Pills” representing dimensions are color-coded blue. [4:19] Dimensions are discreet categorical text strings displayed in labels.

2. [3:25] Drag from among Measures Quantity and drop within the Columns shelf.

   “Pills” representing measures are color-coded green. [4:09] Measures are usually continuous numbers such as counts, dollars, rankings, quantity, etc. These are the metrics we analyze and slice and dice.

3. [3:29] Drag from among Dimensions Segment and drop within the Rows shelf to the right of Category.

4. [3:32] Drag from among Dimensions Market and drop within the Colums shelf to the left of SUM(Quantity). Values are segregated across, starting with Africa.

5. [3:35] Drag from among Dimension Market again and drop it on top of Color (one of the Marks) makes use of Color to differentiate values.

   EXTRA: Notice a Market legend appearing when.

   

   EXTRA: Click on the Swap axis icon to swap X and Y axis (Columns and Rows).

   

   [3:49] Notice Canada is an “emerging” market.

6. [4:41] The video shows a Clear Sheet by clicking the icon. But instead let’s control+click “Sheet 1” and select Rename the sheet to Market Sales.

   

Sales Seasonality View

1. EXTRA: Create a new worksheet.

2. [4:43] Drag Measure Sales and drop it on the left side. This is equivalent to dropping in the Rows shelf.

3. [4:49] Cursor over the blue bar to show a single result - the SUM of all sales.

4. [5:01] Drag Dimension Order Date and drop it on the top box. This is equivalent to dropping in the Columns shelf.

5. [5:07] Click on the [+] in front of the Year (Order Date) pill to get Quarters, shown at the bottom of the view.

6. [5:15] Drag Year to the right of Quarter so years are shown under each quarter.
7. [5:26] Drag Year and drop on Color, which uses different colors instead of columns.

[9:08] Although Office Supplies is doing well, Furniture doesn’t have the same dark green swing. Where is it doing poorly? Is this happening across all stores across sales region?

1. [9:18] Click icon or pull down menu to create new sheet.
2. [9:38] We don’t know how to view the data. So make the Show Me menu visible.

Data Blending

Data Blending is the combination of several data sets for integrated analysis. Although Tableau in 2015 lacked a data modeling diagram view, semantic model development is easy, rapid, intuitive and powerful with one or two combined data sources.

Parameters

Google Analytics

https://www.youtube.com/watch?v=bTU9sOfqjRo describes https://www.youtube.com/watch?v=CAZ3IAJEuCI Tips and Tricks from a Tableau Jedi by Alan Elderidge from Tableau Australia.

http://www.tableau.com/learn/tutorials/on-demand/connecting-google-analytics notes that extracts of Google Analytics are limited to 7 dimensions and 10 measures.

Tableau’s standard extraction from GA is limited in that it uses Sampler. So Google Big Query is a better approach for data extraction.

But Measure Groups pre-selects them

• Bounces
• Exits
• Page Load Sample
• Page Load Time (ms)
• Pageviews
• Sessions
• Time on Page
• Unique PageViews

Tableau Server

The server enables workbooks to be organized into projects and assigned specific permissions by user group.

Sites isolate multiple tenants on the same hardware.

• http://onlinehelp.tableau.com/current/server/en-us/welcome.htm

Tableau Server consists of several processes operating together at the same time (all Multi-threaded and Active/Active HA unless specified below):

• http://onlinehelp.tableau.com/current/server/en-us/distrib_ha_intro.htm
• http://onlinehelp.tableau.com/current/server/en-us/distrib_ha_fail.htm

Access from views embedded in websites use Tableau’s “Trusted Tickets” authentication.

Scalability Analysis

The chart above compares performance from v8.1 vs 8.0, obtained from:
http://www.tableau.com/learn/whitepapers/tableau-server-scalability-explained

See the V9 scalability report

TABCMD utility

Data for the chart above was obtained using Tableau’s TABCMD utility at
https://github.com/tableau/tabjolt/releases

It’s not officially supported by Tableau, which is why many still use NeoLoad and LoadRunner, etc.

Summary of the tech:

• Works only on Windows
• Perfmon counters are enabled in a dataretrieve.config file
• Workbook viz to run are defined in CSV files (not in a GUI)
• Server test config are in .yml files
• JMX used to retrieve metrics
• Written using Java with SWT for the UI.
• Uses ProgresSQL to hold run results
• Custom automation needed to manage files before and after runs

Tableau Extract API

The 22-minute video at http://www.tableau.com/learn/tutorials/on-demand/extract-api-introduction explains the installation of Python 2.7.9 downloaded from http://www.tableau.com/data-extract-api which has both 32 and 64-bit binary Windows and Linux libraries using Python 2.7.9 or C/C++/Java.

[6:27] https://downloads.tableausoftware.com/tssoftware/TDE-API-Python-Linux-64Bit.gz expands to folder DataExtract-8300.15.0308.1149

[6:42] PROTIP: Create a Modules folder within Python27 to hold the DataExtract folder. cd to that folder and run the setup.py file:

python setup.py install

This creates files for this command:

>>> import dataextract
>>> exit()

[8:47] Open IDLE installed with Python.
