The
T most com
mmon examplles include:
a) Creating a listing report with more than one measure – In this case, Measure Values will be
placed on the text shelf. Measure Names will appear on the Column Shelf. Placing Measure
Names on the column shelf provides a separate column with a header for each measure listed.
Otherwise, the values will be written on top of each other in the same column. See the
following article: http://www.tableausoftware.com/support/knowledge‐base/measure‐names‐
and‐measure‐values‐explained.
b) Creating Cross Tabs (also known as Text Tables or Pivot Tables) with more than one
measure in the intersection of measures. In this case, you would have one or more
dimensions on the Row Shelf, another Dimension(s) on the Column Shelf. You would then
place Measure Values on the Text Shelf, and Measure Names on either the Row or Column
Shelf. This is to provide a separate column or row header for each measure displayed
rather than having them over‐write. See the following knowledgebase article:
http://www.tableausoftware.com/support/knowledge‐base/quick‐crosstab.
c) Combining more than one Measure on the same Axis. See the following knowledgebase
article: http://www.tableausoftware.com/support/knowledge‐base/measure‐names‐and‐
measure‐values‐explained.
NOTE: In all cases of using Measure Names and Measure Values, Measure Names are
placed on the filter shelf to allow you to select which measures you want in play (active). A
Measure Values card will also appear showing which measures are in play. Adding or
removing Measures from this card is equivalent to changing the filter on Measure names
from the filter shelf.

‘Make Global’ filters. Understand the difference between local and global filters. Most
people understood that global filters apply across worksheets while local filters apply to only a
single worksheet. Many miss the subtle distinction that global filters only apply to worksheets /
visualizations utilizing the same data connection. Some implications:

If you want a filter to apply to several, but not all worksheets, you can create a
duplicate connection

If you want to have a filter apply to visualizations from different sources in the same
dashboard, parameters or filter actions can serve this purpose.
1.20.
Understand how ‘Context Filters’ interact with Top n filters. Adding a filter to context
implies that a “temp table” is created from the results of that filter. In some cases, this will be a
temp table within the database itself. In other cases, a temporary Tableau Data Extract is
created. The two most common applications of context filters are described in the following
articles:

http://onlinehelp.tableausoftware.com/v6.1/pro/online/en‐us/help.htm (search
“Example – Context Filters”).

2. Building and Understanding Visualization Types
You should understand the common types of visualizations that we create with Tableau, when you
would use each type, and how to create them. A review of common visualization types that you should
be comfortable with is included below:
2.1. Histogram – a histogram is a bar chart showing the distribution of data. It is described in more
detail in the following article: http://en.wikipedia.org/wiki/Histogram. Steps for creating a
histogram in Tableau can be found here:
http://onlinehelp.tableausoftware.com/v6.1/pro/online/en‐us/help.htm (search “Histogram”).
2.2. Sparkline – Edward Tufte invented the Sparkline. There is a great article on what a Sparkline is
and why you might use it written by Tufte: http://www.edwardtufte.com/bboard/q‐and‐a‐
fetch‐msg?msg_id=0001OR. You can find a knowledgebase article on creating a Sparkline in
Tableau here: http://www.tableausoftware.com/support/knowledge‐base/sparklines‐bullets.
2.3. Combo Chart – Combination Charts combine two different mark types in one chart. They
require the use of multiple marks cards. You can find directions on creating these charts here:
http://onlinehelp.tableausoftware.com/v6.1/pro/online/en‐us/help.htm (search “Combination
Chart”).

2.4. Dual Axes Chart – Dual Axes charts use two separate axes to show the data. This article
describes creating them: http://onlinehelp.tableausoftware.com/v6.1/pro/online/en‐
us/help.htm (search “Dual Axes”).

2.5. Cross Tab – Cross Tabs are also often referred to as text tables, pivot tables, and a number of
other names. It is simply having your report broken down with a Column Dimension(s), a Row
Dimension(s) and a Measure(s) at the intersection of each row and column. If you want to have
more than one measure at the intersection, Measure Names and Measure Values come into
play. You can find more information here:
http://onlinehelp.tableausoftware.com/v6.1/pro/online/en‐us/help.htm by searching “Text
Table” or in the knowledgebase http://www.tableausoftware.com/support/knowledge‐
base/quick‐crosstab.
Create a cross‐tab with % of Total Sales and Sales
2.6. Small Multiples – A small multiple is similar to the idea of a Cross Tab in that you have your
information divided by a Row dimension and a Column dimension. However, instead of having
a number at the intersection of the two dimensions, you have a visualization. Here is an article
which describes small multiples: http://en.wikipedia.org/wiki/Small_multiple. Here is a link
that describes creating small multiples in Tableau:
http://onlinehelp.tableausoftware.com/v6.1/pro/online/en‐us/help.htm (search “Small
Multiples”).
2.7. Bullet Chart – A bullet chart / bullet graph is a great way to display how an actual value
compares to a target. It was invented by Stephen Few. You can find a good description of what
a bullet graph is here: http://en.wikipedia.org/wiki/Bullet_graph. This knowledgebase article
describes the steps to create bullet charts in Tableau:
http://www.tableausoftware.com/community/support/kb/bulletgraph.

more details here: http://en.wikipedia.org/wiki/Scatter_plot. For details on creating Scatter
Plots in Tableau search Tableau help for “Scatter Plot”
