How do I change bar color based on y axis value in timechart?

[Digister]

Hi there,

I have already found several answers to the question about how to apply color ranges on the column chart, but I didn't manage to get them to work using a timechart.

My search looks like this:
index="index" startupTime=* | timechart span=1hour count(startupTime) by host limit=0
I have like 100 hosts and I want to mark hosts green which are only having one restart an hour, 2-4 restarts yellow and 4-max red.

Is this somehow possible using a time chart?

Thanks in advance
