Heatmap charts are similar to treemap charts: they both use a similar system of color-coding to represent data values. However, the heatmap chart does not use size to measure data, and instead requires an additional attribute.
The value of each cell depends on the measure you choose under Edit chart configuration.
Change Heatmap Color
By default, the heatmap color is teal in various shades. You can change the heatmap color under chart configuration. To change the basic color the heatmap uses, follow these steps:
1. Navigate to any heatmap chart that you have edit privileges for.
2. Select the Column tile on the left side of your screen.
3. Select the chip for the measure under Value.
4. Click the Color dropdown menu, and select one of the options in the color palette.
Modify Data Labels
By default, heatmaps have data labels enabled for every value. To disable data labels for heatmaps, follow these steps:
1. Navigate to the heatmap you would like to disable data labels for.
2. Select the Data Labels tile in the upper right of your screen.
3. Check "Display on chart." This enables and disables data labels.
Change Chart Gradient
You can now choose multiple colors to define a gradient in charts that support gradients — geo heatmap, geo area, heatmap, and treemap charts. You can control the low, mid, and high values, and numerical value points to customize the gradient.
To define the gradient in a geo heatmap, geo area, heatmap, or treemap chart, follow these steps:
1. Open your chart, select the column tile in the chart builder menu.
2. Navigate to the Gradient section and define the colors for the Min., Mid., and Max values using the color selector dropdowns.
4. In the text boxes, you can define the min, mid, and max points numerically. You can define the min point, max point and mid point as a narrow range if you would rather only see gradients for the top values of your measure.
5. (Optional) Select Flip Color to switch the high and low value colors.
Limitations
Heatmap charts do NOT support conditional formatting.
