Before you begin
Open the custom view containing the chart from which you want to remove a metric. For information, see Display views.
For related concepts regarding charts, see The Parts of a Chart.
After you finish
If you discard changes to the view containing the chart with the deleted metric, you can recover the metric in the chart. However, you cannot selectively discard changes, so you will lose any other changes you made, too. Once you save changes to the view, the deleted metric is permanently deleted and cannot be recovered.
