When I try to copy and paste the graphs into Microsoft Word, I just see a lot of strange text. How do I paste the graph?

 To copy one of the graphs right-click on it and select Copy from the popup menu. By and large you can paste the image into applications using the normal methods. However with Microsoft Word you have to select the Paste Special... item from the Edit menu.

In the dialog that appears, select the Bitmap format and click OK. The image will be pasted into Word.
