The Treemap is a multi-dimensional widget that displays hierarchical data in the form of nested rectangles. This type of chart can be used in different scenarios, for example, instead of a column chart if you have to compare too many categories and sub-categories. You can find more details on the Treemap Widget here.
The Treemap can also serve a dual purpose in the form of a selector and contribution visualization.
The Treemap in the above image can be used as a selector to filter the dashboard by Product Category and show the contribution of that Product Category by number of orders.
How to Create a Treemap Selector
Limitation: If you choose to use a value in the Treemap with many categories, since the Treemap sizes by contribution the smaller categories might be to small to see/select. In this case if you still want to use the Treemap for a selector, just remove the value. The Treemap will show evenly spaced categories.
You will notice that the Treemap Widget has a minimum height. To overcome this limitation we will start with an Indicator Widget.
1. Create an Indicator Widget with the value of your choice
2. Size the Indicator Widget according the desired height for the Treemap
3. Edit the Indicator Widget. In the Widget Editor, switch the widget type to Treemap
4. Select Apply. The Treemap will now fit within the bounds of the previously created Indicator Widget
