Hi,
I have in Elastic the below data:

I also made the below graph :
Vnf z1 has as counters MemUsed & CpuUsed, whereas vnf z2 has as counters CpuUsed & MaxCpuUsed.
If I filter the above graph with "vnf_name is z1" and after that I want to filter with a specific counter, could it be possible only MemUsed & CpuUsed to be shown in the drop down menu of counter_name.keyword ?
Thank you in advance!
