Data Axis
Because Optimize can display instances of KPIs associated with different types of data such as monetary values, bytes, percentages, and time on the same KPI performance chart, scale values and units do not display along the y axis. To display scale values for an instance of a KPI, click its performance line or its name in the legend below the performance chart. The units of measure for each KPI performance line display in the legend.
Note:
If all the KPI instances on a performance chart share the same type of data, scale values still do not display. You must click the KPI instance's performance line or its name in the legend to see its scale values. Although the KPI instances share the same units, the scale values may differ. For example, one KPI instance's performance may have a high point of 45 bytes and a low point of 12 bytes. The KPI instance's scale values might range from 10 to 50. Another KPI instance's performance may have a high point of 153 bytes and a low point of 86 bytes. That KPI instance's scale values might range from 80 to 160.
