Is there a limit on the number of groupings a chart in a saved view or widget can have?

When viewing an Opportunities saved view in chart mode, there is a limit of 30 total grouping combinations that can be displayed. For example, if you apply two groups to your chart, with one group having four options and the other having 8, then the total possible combinations equal 32 and exceed the limit of 30. When this occurs, we will display the below warning above the chart to let you know there is a limitation on what can be displayed.

N.B. Please note that this limitation only applies to String fields. For example, if you are applying two String fields as groups, then the limit will be 30. However, if you use a String and Picklist combination, the limit is greater than 30.

To work around this, you can either use fewer groupings for your chart or alternatively, only select specific values within a grouping to show in the chart. To do this, hold Ctrl (Windows) or Cmd (Mac) and click on each of the values you want to show in the chart to select multiple.
