calendar heatmap viz force value=0 different color?

[pmeyerson]

Is there a way to force one of the color bins to be for 0 value? Or some other splunk ninja magic to gray out those days on the calendar heatmap? The data has high spikes and many 0s. | timechart span=1d limit=0 count by status. I have some days with low values that get colored the same as 0. Splunk 6.6.2. Thanks for any suggestions.

nulls are black instead of being colored. if you can force your zero's to be nulls or maybe only return data that is greater than zero your zeros will become null?

You saved my time, thanks !

This works, but has an unexpected bug (seemingly) --- for null values between the current date and the most-recent event, the boxes are colored grey rather than black.

Actually, I used only search count>0 and it did what I was looking for

[dijikul]

Yes! That did it! Search count>0 rather than converting to null, and the viz shows 0-counts as grey.

Perfect!

Adding to @kmaron's point try the following run anywhere search with Calendar Heat Map visualization:

index=_internal sourcetype=splunkd log_level!=INFO
| timechart count
| eval count=case(count!=0,count)

This will fill count values as NULL and hence the visualization will color NULL with BLACK color.
