Thanks a lot Cliff & Birkir, I think these examples will help a lot of
people both writing and reading these documents. I know Jared will be kind
enough to publish the results :)

Lucica, I can't do it right away, but with Birkir's help I'm working on that
for my own organization. I'll see with Jared if we can get a set of
exemplary files loaded to WebAIM.

Could someone attach here an example of accessible PPT and Excel file so we
can all learn from examples?

Thank you,

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
