# CPU Widget
|
||
|
|
|
||
|
|
The CPU widget displays a visual representation of CPU usage over a time range.

|
## Features
|
||
|
|
|
||
|
|
The CPU widget is composed of two parts: the graph and the legend:
|
||
|
|
|
||
|
|
- The graph displays the usage data for the currently selected entry as a percentage
|
||
|
|
- The legend displays all available entries that can be displayed on the graph along with their last recorded use percentage (except for the "All" option)
|
||
|
|
|
||
|
|
Users can scroll through the legend using either the keyboard or mouse to select which entry to display on the graph. The "All" option shows every entry
|
||
|
|
at the same time, though this may get a bit hard to follow if you have a large number of cores/threads.
|
||
|
|
|
||
|
|
One can also adjust the displayed time range through either the keyboard or mouse, with a range of 30s to 600s.
|
||
|
|
|
||
|
|
