Performanche Chart Legend Values

I'm trying veeam monitor (version and i have a question about the values shown in the Performanche Chart Legend.
For each object monitored, there are many columns but my attention goes to this two: Minimum and Maximum.

The disk chart (but the others too), is strange because, for the same monitored object, if i choose "past hour", obtaining in this way some values for minimum and maximum, how it's possible that the maximum value shown when i change the period (past day, week etc) is lower than that shown in "past hour"?

How accurate are the values ​​shown in these charts?

Thanks in advance

This mismatch is caused by different aggregation intervals being used for selected time periods. Take a look at the details below:

• "Past hour" uses 20 sec time stamps
• "Past day" uses 300 sec time stamps
More than one day -7200 sec for each time stamp

In other words, the further you go in the past on the performance chart, the smoother line you'll have, which in turn means that maximum and minimum values will be picked based on the smoothed line.

Thank you!
