The graph has a Density mode and a Distribution mode.
Density mode
Shows how often the metric had each particular value.
Distribution mode
Shows the percentage possibility that the metric was at or below the x-axis
value. The y-axis always ranges from 0 to 1. The right edge of the graph
always reaches a value of 1, which shows that all received readings were at
or below the maximum value indicated on the x-axis. At any point in the
middle of the graph, the y-axis value is the percentage of collected values
that were at or below the x-axis value, or the probability that any one
collected value was at or below that value.
To change the graph to Distribution mode, click the Change to distribution mode icon.
If you graph only one time period in either mode, the graph might include vertical lines at the 75, 90, and 95
percent levels. You can edit the widget to add or remove the percentage lines.
You can click the Date Controls icon to change either or both time periods on the graph. In the two drop-
down menus that appear, select the time periods for the graph. To show only one time period, select Not
Selected from the second drop-down menu. You can click the Date Controls icon again to hide the date.
Configure the Data Distribution Analysis Widget
You can select the metrics that the Data Distribution Analysis widget shows by editing the widget
configuration.
You can also configure other widgets to provide metric selections to the Data Distribution Analysis widget.
See “Configure Widget Interactions,” on page 63.
To define a fixed set of metrics for the widget to draw when you select a particular resource, see “Define
Metric Sets for a Widget,” on page 113.

Procedure
1 Set Self Provider to On to define metric selections in the widget configuration.
2 (Optional) Select one or more tag values in the Resources-Tags pane to filter the resources that appear
on the List tab.
You can use icons on the toolbar at the top of the list to collapse, expand, and deselect all of the tags in

that you select. When you click the Invert Result icon, the list includes only resources that do not match
the tag values that you select.
