perhaps a dumb question, but I've never been afraid to ask them. We're submitting to a journal that wants figures attached as jpgs. So I've copied the graphs I created in excel into photoshop, then added legends etc there. Problem is, the stuff that is copied from excel looks really bad - faint and fuzzy. Is there a better way of creating graphs and saving them as jpgs? (using BIAC-available software...)
You can do the same thing by pasting the graphs into PowerPoint; use the Paste Special, Paste as Windows Metafile (or similar) to copy the graph itself and not insert it as an object.
Then, save the pages as jpegs. If you need resolution to increase, you can increase the size of the page in PowerPoint, which increases the effective resolution of the jpeg.
