Hi
I'm AnnaThomas and I'd be happy to help you with your question. In this Forum, we are Microsoft consumers just like yourself.
Here are a few possibilities:
The chart is a picture: If the chart has been copied and pasted as a picture onto the same sheet, the "Chart Data Range" option will be disabled.
The chart is linked to an external data source: If the chart is linked to data in another workbook, the "Chart Data Range" option will be disabled.
The chart is a combination chart: If the chart is a combination of multiple chart types, the "Chart Data Range" option will be disabled.
The chart is a PivotChart: If the chart is created from a PivotTable, the "Chart Data Range" option will be disabled.
I hope this helps ;-), let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.
Best Regards,
AnnaThomas
