RMS versus X axis range


In Root 5.16.00 RMS displayed in a pad changes a bit when X axis is zoomed/unzoomed. What is the reason for that? Is there any way to forbid this, if it’s the feature?

When zooming on an axis, all the stats quantities are recomputed using the current axis range. Use Unzoom to go back to the quantities computed at fill time for all bins.
