Directus Treemap Chart Panel

Present a cluster or boxes where the size of each box represent the value. You can also group data into categories which are presented in different colors.

Usage

If you choose to group the data into different series, a legend will appear at the bottom. Hover over a series in the legend to highlight all data for that series. You can also toggle which series are visible by clicking the series label in the legend.

• Collection Selection
• Filters
• Label Field
• Value Field
• Group Aggregation (Sum, Average, Count, Max and Min)
• Series Field
• Hide/Show Labels
• Hide/Show Tooltips
• Color

Requirements
