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.
We can create a Bullet graph with just 2 measures! This method requires the LEAST number of fields possible to create this type of chart.
The best way to tackle such questions in the exam is to click the "SHOW ME" button on top right, and hover over the chart we want to create.
In our case, it is a Bullet graph.


Therefore, we need 2 measures at least to create this chart, and 0 or more dimensions.
