The Config tab in OpenObserve dashboards allows users to customize the behavior, layout, and appearance of individual panels.

The **Config** tab is organized into collapsible sections (General, Legend, Data, Axis, Labels, and more). Use the **Search config** bar at the top to filter settings by name, and the expand/collapse toggle to open or close all sections at once.
