How can I have one color per unique machine_id? In the below graph I have two machine Ids listed on the top right hand side, but I would like to have different colors for each instead of them being all green.
Here is my code:
`.es(index=stage-athena-aux*, metric=avg:hours_per_device, timefield=capture_local_date, split=machine_id.keyword:2).color(green).title('Hours of operation').label(regex='.* machine_id.keyword:(.*) > .*', label='$1').bars(width=11).legend(ne)`
and here is my graph:
