Panel editor

In the panel editor, you can update all the elements of a visualization including the data source, queries, time range, and visualization display options.

This following sections describe the areas of the Grafana panel editor.

Panel header

The header section lists the dashboard in which the panel appears and the following controls:

Back to dashboard - Return to the dashboard with changes applied, but not yet saved.
Discard panel changes - Discard changes you have made to the panel since you last saved the dashboard.
Save dashboard - Save your changes to the dashboard.

Visualization preview

The visualization preview section contains the following options:

Table view - Convert any visualization to a table so you can see the data. Table views are helpful for troubleshooting. This view only contains the raw data. It doesn’t include transformations you might have applied to the data or the formatting options available in the Table visualization.
Time range controls - Default is either the browser local timezone or the timezone selected at a higher level.
Refresh - Query the data source.

Data section

The data section contains tabs where you enter queries, transform your data, and create alert rules (if applicable).

Queries - Select your data source and enter queries here. For more information, refer to Add a query. When you create a new dashboard, you’ll be prompted to select a data source before you get to the panel editor. You set or update the data source in existing dashboards using the drop-down in the Queries tab.
Transformations - Apply data transformations. For more information, refer to Transform data.
Alert - Write alert rules. For more information, refer to the overview of Grafana Alerting.
