The Heatmap element shows the counts or average values for groups of observations using a color intensity scale. If you plot a single variable as either Y or X, your plot appears as bars. If you plot a cross tabulation of two variables Y and X, your plot shows rectangles.
When you create a heatmap, an intensity legend appears in the Legend area. See Discrete or Continuous Legend Items. The intensity legend shows counts or average values:
For examples illustrating the heatmap element, see Example of Wafer Maps Based on a Cluster Analysis in Graph Builder Examples and Example Using a Heatmap to Apply Background Colors in Graph Builder Examples.

Tip: If you have multiple graphs, you can color or size each graph by different variables. Drag a second variable to the Color or Size zone, and drop it in a corner. In the Variables option, select the specific color or size variable to apply to each graph.
