Area Charts

Area charts are used to compare percentage values for two or more resources over a period of time. An area chart is similar to a line graph, but in addition, the area under the line is filled in with a color or pattern. Each line represents a resource (drive or media) or other category of data, and the size of the area under the line represents the resource’s percentage of the total. Time is always displayed on the horizontal axis. Each point on the line represents an actual data value at a point in time.

Note – The default date range for most STA area charts (libraries, complexes, drives, and media) is the last 30 days. For exchanges, the default is one day—the current date.
