Bullet Chart in Tableau



What is a Bullet chart?

A bullet graph is a variation of a bar graph developed to replace dashboard gauges and meters. A bullet graph is useful for comparing the performance of a primary measure to one or more other measures. Below is a single bullet graph showing how actual sales compared to estimated sales.


Let me explain it through one example. We will take Sample-Superstore dataset and make one bullet chart. What are our requirements:

1) 0 or more dimensions : Sub-Categories

2) 2 measures : (Sales of 2019, Sales of 2020)


What do we want to achieve?

We want to see how 2020-Sales are performing as compared to 2019-Sales for various sub-categories


How to make the Bullet Chart in Tableau?

  1. Open Tableau Desktop and connect to the Sample-Superstore data source.

  2. Navigate to a new worksheet.

  3. First we need to create calculated fields for Sales_2019 and Sales_2020 as below

4. Bring SUM(Sales_2019) and SUM(Sales_2020) in columns and "Sub-Category" in the rows

5. Go to "Show me" and click on "Bullet Graph"



6. You might need to switch the reference line fields as Sales_2019 is shown instead of Sales_2020 in bars




7. Now it looks good.



8. You can change the distribution (by defalut it takes 60,80%. You need to Right-click ( the on the axis and select Edit Reference Line, and then select one of the reference lines to modify.




We can add Sales_2020 in Label to know the exact numbers
