password protection for PP Charts

[IRI]

Is there a way to password-protect a powerpoint chart?

You could make the charts in Excel and copy as picture and paste into
PPT. Those would not be editable.

Or you could copy the chart in Excel on a chart sheet to a new single
sheet workbook and that would still be linked to the source data, but
if you didn't distribute the source data workbook, they wouldn't be
editable.
