For example, using the Cities.jmp sample data table, specify a continuous Coloring variable as follows:

Select Help > Sample Data Library and open Cities.jmp.

Select Graph > Legacy > Treemap.

Select city and click Categories.

Select OZONE and click Coloring.

Figure 10.11 City Colored by OZONE

Note that the size of the rectangles is still based on the number of occurrences of the Categories variable, but the colors are mapped to ozone values. The high ozone value for Los Angeles clearly stands out. Missing values appear as black rectangles.
