Items needed to build this chart are as follows:

Columns	Measure
Rows	Measure
Marks	Density
Detail	Dimension

The following steps will describe how to build a heat map:

1. From the Data pane on the left, select the dimension or measure that you want to visualize using the density chart. In the preceding example...
