SolutionSolution

This issue occurs due to field name conflicts. The name of the field you add must not coincide with any existing field in the dataset. Check that you set a unique name for this field in your dataset.

A field with this name might have been added to the chart first, and then to the dataset used for the chart. In this case, rename the field added to the chart.
