Greetings all,

Are Powerpoint 2007 charts and graphs inherently accessible, since
they include the data chart/excel spreadsheet?

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

No, I don't think they are accessible.
Even if you have the same data the screen reader may not see, or
interact with, it the same way as in Excel, since they are not set up
in a column and row format with cells.
If you mean the underlying Excel spreadsheet comes with the
presentation, that might be sufficient.

We teach Office 2007 accessibility and I always tell the students they have to add alt text to PowerPoint charts and graphs. JAWS will not read the underling excel data so you have to set the alt text to match what the chart visually displays.

In Excel 2007 JAWS reads the underling cell data for the chart or graph so there is no need to add alt text there.

Keep in mind that it depends on which view of the presentation you are
providing to participants. If you are giving them the presentation or PPTX
document then Excel and Word content that has been embedded will be
accessible and you can open the original Excel or Word document from the
slide/provided it is in the same folder as the PowerPoint document and is
available to participants. However if you provide the PowerPoint show, the
OLE objects such as the Excel or Word documents or pieces of content from
them will not be accessible and will be objects that require Alt Text. It is
the same if you convert the PowerPoint document to tagged PDF...those linked
objects that were accessible in the Normal slide view of the presentation
are figures that require Alt Text.

I did a workshop yesterday on accessible Office documents and the key for
PowerPoint is to decide how the PowerPoint document will be distributed
before you begin adding content because that determines what type of content
you can add to slides.

Cheers, Karen

One additional item to consider is whether or not the user is familiar with PPT. We have found that the skill level among screen reader users with both PPT and Excel really varies and is generally dependent upon whether they regularly use the program as a part of their job. Thus people who use screen readers and give a lot of presentations are highly skilled and can get to embedded content like spreadsheets, but the average user has not been able to do this. We recommend keeping things simple for PPTs that are distributed to a general audience.

Either that, or distribute the Powerpoint files with a little hand
out, explaining how to navigate PP documents.
In general, I wonder if any such guides exist and if it might be a
good idea to compile them.
Powerpoint with Jaws/Window Eyes, Google Docs with Jaws (an exercise
in frustration) etc.
I've done the screen reader specific instructions for a few minor
software things and users have very much liked them.
I was asked to write up a little guide for screen readers as a temp
solution for a web site that was not overly accessible, but going
through an update.
The guide explained how to do certain things on the site, step by step.
I've never seen anyone else try this, and it is true that web sites
should never require user guides for how to perform certain things,
but it was actually quite popular with the users of this site.
They felt they learnt something new with their screen reading software.
I guess I am not sure where I am going with this but, generally, I
think trying to push your users, teach them something new, ease them
into using Powerpoint, may be a good thing to do in some situations,
mostly educational settings.
It all depends on your audience.

Birkir, I feel that your "guide to our site" should be a standard
feature of all sites. Include one section on things that work ("We do
use headings to achieve proper semantic structure, so you can rely on
them for fast navigation of our pages.") and another on things that
don't work or barely work ("We do not have captioning for our videos,
but we have provided a text transcript and audio description for each
one. The first link immediately after each video is its transcript. The
second link is its audio description.")

Yes, it takes work, and it takes a coordinated effort in building the
site, but it seems to me that your experience demonstrates that users
would appreciate these tips.

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.

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

Thank you,
Lucica

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.

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 :)

Hi again, this interesting info was released on twitter today -
Accessibility of Office Documents and Office Applications -
http://adod.idrc.ocad.ca/ - teaching us how to create accessible
spreadsheets, presentations and word documents.

I was thinking that it matches the overall thread of discussion and might be
helpful for us all.
