How to add a unit with a value to a timechart?

[chanduira]

Dear Experts,

We are trying to add unit with a value to a timechart.
My search is:

index = xyz sourcetype = csv source = "C:\\Users\\co*" | eval Capacity =IPDU1_power+IPDU2_power | timechart avg(Capacity) by Rackno 

This search will give an output like Capacity by Rack in timechart. I want to add "KW" unit with Capacity of each rack.

Please help I try with option

| eval Capacity=Capacity."KW" this did not work

Once you add the string unit KW to the values, it becomes string which you can't plot (only numerical values for y axis). Better option would be to add unit in the y axis label.
