Bar Chart
The Bar Chart panel visualization enables you to represent categorical data graphically, particularly when you want to visualize data from a specific field across all devices in a fleet dashboard.

Go to the Dashboards tab, select the desired dashboard, and click on the + Panel button to create a new panel.
Select Bar Chart Panel

Configure General Settings
In the General tab:
- Title: Add a title for the panel (optional).
- Stream: Select the data stream to use.

- Aggregated Field: Select the column you want to visualize (e.g., range, timestamp).

For instance, you can group data by firmware version to visualize the average range value across different firmware versions.
