Does anyone else see Major differences from Version 9.0 to Version 9.1 for Percent Utilization Graphs?

The above is from Version 9.1

The above is from Version 9.0
Both are collected using “every 10 minutes” for time period “7 days”
Perhaps there is a way to return to the Graph of Version 9.0 as it is much nicer and accurate IMO.
