Chart configuration reference
Chart overview
The <chart> element is a panel visualization that is highly configurable.
| <chart> |
|---|
A panel that displays search data in a chart. Saved reports contain chart formatting parameters. Saved searches do not. For more information, see "Save reports and share them with others." When you load a saved report in the chart panel, your saved report format is also loaded. However, chart formatting can be overridden inline using the chart options. Charts use named options to specify chart-specific properties. This reference contains sections on all configurable properties of charts. |
