  • Dashboard settings (gear) icon - Click to access the dashboard settings.
  • Discard - Discards all changes you have made to the panel since you last saved the dashboard.
  • Save - Saves the dashboard, including all changes you have made in the panel editor.
  • Apply - Applies changes you made and then closes the panel editor, returning you to the dashboard. You will have to save the dashboard to persist the applied changes.

Visualization preview

The visualization preview section contains viewing options, time range controls, the visualization preview, and (if applicable) the panel title, axes, and legend.

  • Table view - Convert any visualization to a table so that you can see the data. Useful for troubleshooting.
  • Fill - The visualization preview will fill the available space in the preview part. If you change the width of the side pane or height of the bottom pane the visualization will adapt to fill whatever space is available.
  • Fit - The visualization preview will fill the available space in but preserve the aspect ratio of the panel.
  • Exact - The visualization preview will have the exact size as the size on the dashboard. If not enough space is available, the visualization will scale down preserving the aspect ratio.
  • Time range controls - For more information, refer to Time range controls.

Data section (bottom pane)

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

  • Query tab - Select your data source and enter queries here. For more information, refer to Queries.
  • Transform tab - Apply data transformations. For more information, refer to Transformations.
  • Alert tab - Write alert rules. For more information, refer to Create alerts.

Panel display options (side pane)

The section contains tabs where you configure almost every aspect of your data Visualization. Not all options are available for each visualization.

The data model used in Grafana, namely the data frame, is a columnar-oriented table structure that unifies both time series and table query results. Each column within this structure is called a field. A field can represent a single time series or table column.

Field options allow you to change how the data is displayed in your visualizations. Options and overrides that you apply do not change the data, however they change how Grafana displays the data.

Field options

When you change an option, it is applied to all fields, meaning all series or columns. For example, if you change the unit to percentage, then all fields with numeric values are displayed in percentages.

Field overrides

Field overrides can be added or viewed in the Overrides tab in the panel editor side menu. You can apply options to specific fields (series or columns) rather than all fields. Learn how to apply an override in Field overrides.

Options are documented in the following topics:
