The zoom preview panel has sliders that you can use to filter the overall duration in the chart
window and view data for a particular focused duration. You can drag the sliders on either side
of the time scale to increase or decrease the duration for which you want to view the data points.

When can I add new chart windows to the Chart Work Area?
By default, performance graphs of resources are plotted in the same chart window for metrics that
belong to the same metric category. If you want to view their performance graphs in separate chart
windows, do the following:
1. Click Add New to add a new chart window to the Chart Work Area. The new chart window is
automatically selected.
2. Clear the selection of the active chart window in the Chart Work Area, by clicking the chart title
bar. Then, select the resource or metric under Charts. The subsequent performance graphs of
resources for metrics belonging to the same metric category are automatically added to the new
chart window. This continues till you clear the selection for the new chart window.
Why is it that the Choose Metrics box is disabled when I click the Cache node
for one of the XP or P9000 disk arrays under Charts?
The Choose Metrics box is disabled when you click the Cache node, because the configuration data
collection is not yet performed for your XP or P9000 disk array, and the CLPR partition data is not
available with P9000 Performance Advisor. Perform configuration data collection for your XP or a
P9000 disk array to view the Cache related metrics in the Choose Metrics box.
Why are the virtual volumes like ThP or snapshot pool volumes not displayed
for my XP or a P9000 disk array?
The virtual volumes like ThP or snapshot pools are displayed only if those resources can be configured
on your XP or a P9000 disk array. Therefore, verify if your XP or a P9000 disk array supports virtual
volumes to be configured.
Does the Legends check box selection in the individual chart windows override
the Show Legends check box selection in the Chart Work Area?
Yes. If the Legends check box is selected in the individual chart window, it supersedes the Show
Legends selection in the Chart Work Area.
