Hey everybody,
I have this code for a heatmap. Currently, the colors are totally random, and i want a specific color, associated with the number of COVID cases. to be in a specfic district. No idea how to do this, I've tried to search for ways to do it but i think I'm using the wrong keywords. If anybody could explain to me how to do this, it would be grand.
Best regards,
Fran

Hi,
The colormap can be used to change the colors in the plots. The colors are not random but taken from a set scheme as you can check in the documentation. You can also give a custom colormap as per your requirement.
Just update the colormap in this line (line 43) of your code.
colormap( OverlayImage.Parent, jet );
Hope this helps !!
