Hello .

I am using heatmap visualization and counts that are 0< are showing as expected ,
however counts that are =0 aren't showing in cells which 0 is the value that I expect to be shown. I am using terms aggregation for x and y axis. Legend displays 0 - 200 so I think 0 should be shown in the cells.

I read below post but solution was not provided so I decided to post my thread.

Is there anyway to show 0 using terms aggregation ?

Thanks,
