A bullet graph is a bar chart with a target line. A typical bar chart will have one or more dimensions on the Rows and a Measure on the Columns for a horizonal bar chart, or vice-versa for a vertical bar chart. Adding a Reference Line will create the target line for the bullet graph. This can be based on Measure which is placed on the Details of the Marks Card. In addition, bullet graphs can have performance bands. The performance bands are created using Distribution Bands.
