Polish the Y-Axis of the Insights charts
As noted here: gitlab-org/quality/team-tasks#129 (comment 177343080)
Another observation from me, is there a reason to have decimal numbers in the y axis for issue counts?
The chart shows only 1 issue. I was expecting the y axis to be 1,2,3,4,5,6,7,8 and the bar shorter. We may need to look into default graph value/height ?
We should improve that.
