No in PowerPoint the data that generates the chart, shown in an excel window when you create a PPT chart or edit the chart data, is not accessible. At least not when viewing the slide.

So the only way to make chart or graph accessible in PowerPoint is to manually add alt text.

A chart created directly in Excel is accessible and does not need alt text because JAWS reads the tabular data used to generate the chart. At least this is my experience so far.

Really? That is pretty neat that Excel data is accessible in PP, I did
not know that.
If you don't mind, I'd love to get a copy of an accessible pp set with
Excel data, just to see how it works.
Onlyif it is convenient.
Thanks
