This depends on what you need.
Do you need to automatic generate documents?
Or do you want te end user to be able to use QV-charts in a Word document?
For the first option I use the Report function and send it to PDF-printer so it creates PDF-files.
For the second option I most of the time use the Special Icon options on the Caption tab.
"Send to Excel", if you want to be able to edit the date of a table charts
"Copy Image to Clipboard" , if you just need the charts (then ctrl+v in whatever application you want to use it)
Hope this helps.
export the chart to ppoint as an image or an interactive chart?
if as an image, you can use the "Print" menu by right click on the object that you want to export. Your browser will open a new tab/window with the object in there, from here you can copy as an image and paste it to your ppoint slide.
