Description Yuri Rudman 2017-12-19 23:31:32 UTC 
Description of problem:

'Virtual Machine CPU States' chart does not work correctly when some numbers are 0. 
1. When both metric are shown - red line for 12/01-12/11 should be 0
2. '% Used' show different data for 12/15-12/18 if shown alone vs together with '%bReady'
Note: tooltips are correct in both cases.


Steps to reproduce:
1. Navigate to VM named "cu-24x7"
2. Monitoring -> Utilization
3. Change 'Show' to 3 weeks

I was able to reproduce it. I am pretty sure that the data are correct. The 'Virtual Machine CPU States' chart is using Stacked Area chart, that should behave exactly like this. It aggregates the individual values.

I agree that this is not intuitive, so I can replace Stacked Area charts for Area charts in the definitions that would not aggregate values.
