**Matrix Diagram**

**Description**

A matrix diagram is great for comparing three different variables at the same time. Circles are positioned on the diagram as they correlate to the X and Y axis variables and the variable is represented through the size of the circle.

A matrix diagram accepts one **Row Field**, one **Column Field** and one **Measure** data columns for input.

Remember to select an **Expression** for **Measure**. You can do this by clicking on the field first and then choosing from the drop down. If you select non-numeric data, the **Expression** will be **Count**.
