create a calculated field
The added calculated fields are not saved in the dataset and only apply to the current chart.
If you create another chart and select the same dataset for the chart, the calculated field that you add is lost.
You copy data from a source chart that contains a calculated field to a destination chart. If the destination chart uses the same dataset as the source chart, the calculated field takes effect in the destination chart.
For more information, see Create a calculated field.
