Using Tree Maps

Tree maps display hierarchical data in the form of nested rectangles. For example, you can use a tree map instead of a bar chart to compare a large number of categories and subcategories.

Tree map

Tree maps let you visualize one or two measures for a dimension. Each rectangle on the tree map represents one item in the dimension and the rectangle size is proportional to the value it represents. You can also use rectangle color to represent another measure for the item and show where the value of the item falls within the range for the measure. Darker colors indicate higher values and lighter colors indicate lower values.

Tree maps show up to 100 data points for the Group by field.
