Using tree maps - Amazon QuickSight

Using tree maps

To visualize one or two measures for a dimension, use tree maps.

Each rectangle on the tree map represents one item in the dimension. Rectangle size represents the proportion of the value for the selected measure that the item represents compared to the whole for the dimension. You can optionally use rectangle color to represent another measure for the item. Rectangle color represents where the value for the item falls in the range for the measure, with darker colors indicating higher values and lighter colors indicating lower ones.

Tree maps show up to 100 data points for the Group by field. For more information about how Amazon QuickSight handles data that falls outside display limits, see Display limits.

The icon for a tree map is as follows.

Creating a tree map

Use the following procedure to create a tree map.

To create a tree map
  1. On the analysis page, choose Visualize on the tool bar.

  2. Choose Add on the application bar, and then choose Add visual.

  3. On the Visual types pane, choose the tree map icon.

  4. From the Fields list pane, drag the fields that you want to use to the appropriate field wells. Typically, you want to use dimension or measure fields as indicated by the target field well. If you choose to use a dimension field as a measure, the Count aggregate function is automatically applied to it to create a numeric value.

    To create a tree map, drag a measure to the Size field well and a dimension to the Group by field well. Optionally, drag another measure to the Color field well.

  5. (Optional) Add drill-down layers by dragging one or more additional fields to the Group by field well. For more information about adding drill-downs, see Adding drill-downs to visual data in Amazon QuickSight.
