G'day,
I am trying to change the background color of a heatmap.
In the below heatmap, the white part should be a different color. I can only change it by selecting a different theme, but I need to change it to a color that's not part of the standard themes listed here https://ej2.syncfusion.com/documentation/api/heatmap/heatMapTheme/ .
Any help is very much appreciated as I couldn't find any solution in the documentation nor the forum.
Thank you,
Daniel
