[Monitoring] All % graphs should start at 0 on the y-axis

[chrisronline]

This came from a comment in this PR where we shouldn't show negative values on the y-axis for graphs showing percentages.

I'll go back and add the list of known affected graphs later.

It might be as easy as applying this logic for the y-axis too

Hi @chrisronline . I'm interested in working on this issue. I tried to play around with the charts and I think I may have found the fix. I'm not super familiar with kibana graphs - are "graphs showing percentages" always flot charts? I made a one line PR for this but do let me know if anything needs to change

Hi @pohzipohzi

Thanks for the contribution! I will take a look at this soon and get back to you.

Thanks again!

hi @chrisronline does this issue still persist?
If you are using elastic/charts this issue should not be present. If so can we close it?
