[TABLEAU] Bullet Graphs


   Bullet Graphs


A bullet graph is a variation of a bar graph developed to replace dashboard gauges and meters. The bullet graph is generally used to compare a primary measure to one or more other measures in the context of qualitative ranges of performance such as poor, satisfactory, and good. For example, below is a single bullet graph showing actual sales compared to an estimate.


Step 1


Hold down the Ctrl key and select two measures in the Data window.

Step 2


Click the Show Me! button on the toolbar and select the Bullet Graph view type.

 



Two types of reference lines are added: one to indicate a target or goal and another that shades the distribution to show ranges of performance.

Step 3


Sometimes you may want to swap the reference line fields. For example, the actual sales is shown as a reference distribution instead of a bar. Swap the two measures by right-clicking the axis and selecting Swap Reference Line Fields.



Step 4


You can refine the view by editing the reference lines. Right-click the axis and select Edit Reference Line. Then select one of the reference lines to modify. You can specify new values to reference as well as formatting options.





Add measures to the Level of Detail shelf to make them available as the target measure.
