+# Legend
+
+Use the legend to adjust how a visualization displays series. This legend functionality only applies to a few panels now, but it will eventually be common to all visualizations.
+
+This topic currently applies to the following visualizations:
+
+- [Pie chart panel]({{< relref "pie-chart-panel.md">}})
+- [Time series panel]({{< relref "time-series/_index.md" >}})
+
+## Toggle series
+
+To toggle a series:
+Click on the series label in the legend to isolate the series in the visualization. 
+All other series are hidden in the visualization. The data of the hidden series is still accessible.
+
+Use Cmd/Ctrl+click on the series label to hide the isolated series and remove the toggle.
+
+> **Note:** This option is persistent when you save the dashboard.

+
+This creates a system override that hides the other series. You can view this override in the Overrides tab. If you delete the override, then it removes the toggle.

+
+## Change series color
+
+Click on the series icon (colored line beside the series label) in the legend to change selected series color.
