An on-line library for creating different chart types in Tableau


Tableau Canvas Layout:

A slopegraph will have one Measure on the Rows and one Dimension on the Columns. Lines are what take up most spaces in slopegraph. Therefore, it is used to when you want audience to focus on changes or difference between categories. In this blog post, I will walk you through two ways of creating a slopegraph.

Data Set 1: Sample Superstore Dataset

Data Set 2: State of America Rankings Dataset

Building a Slopegraph

1. Using single Date field

Opening the Sample Superstore dataset:
     Double-click Sales or drag to Rows
     Double-click Order Date or drag to Columns
     Select Entire View from the Drop down box (optional)
     Add Order Date on filters (Year) and select the two most recent years
     Move State to Detail
You now have a slopegraph.

Using Measure Values field

Opening the State of America Rankings data:
     Drag Measure Values to Rows and Measure Names to Columns
     Move Measure Names to Filter. Select only 2012 Ranking and 2013 Ranking
You will have the following canvas.

Change Marks card to Line. Create a calculated field:

     Calculated Field: Ranking Change
     [2013 Ranking] - [2012 Ranking]

Drag the calculated field to Color and State to Text.

Notice that State labels could get overlapped with each other. Here I filter out a few to make the graph easier to see.
