Change series values format type

[nasanchez]

I am using several types of graph with PHPPresentation, in example, a 3D pie chart like this:

As you can see, numbers are 66,7 and 33,3. If I use the function $series->setShowPercentage(true); I have this values shown as % but when I go to PPT option 'Edit values in excel' these values are in general format.

I would like that these values were in % format. Is there any way to change this?

Thanks!
