By default, the minimum and maximum values of a chart's Y-axis — that is, its range — is not set until the first metric value is displayed. As metric values arrive and are plotted in the chart, the Y-axis range is adjusted automatically so that those metric values fall within that range. However, you can disable automatic Y-axis range adjustment and specify minimum and maximum values for the Y-axis that remain fixed.
Likewise, if a chart has a fixed Y-axis range, you can restore automatic adjustment.
To control a chart's Y-axis range:
The Chart Properties dialog box is displayed.
The minimum and maximum values set prior are ignored.
Changes to a chart's Y-axis range remain in effect for a user until the user changes them.
