Heatmap charts

Heatmap charts use color intensity to represent data values in a two-dimensional matrix. They are effective for identifying patterns, correlations, and anomalies in large datasets, and are commonly used for visualizing correlation matrices, geographic data, time-based patterns, and categorical comparisons.

  • Gridlines and padding between bands — Gridline and band padding behavior is planned for update in the new renderer.

  • Custom font support — Custom font settings apply differently compared to classic charts.

  • Data label styling and text backgrounds, borders, and alignment

Configure a Heatmap chart

To create a Heatmap chart:

  1. Start a new search or open an existing Answer.

  2. In the chart selector panel, select Heatmap from the New section.

  3. Add at least one measure and two attributes to your query.

  4. The chart renders a color-coded matrix based on your data values.

  5. Use the chart settings panel to configure color scales, faceting, and trellis options.
