George,
For audiograms, physicians need manually setting some values directly on graph, besides manual entry. We did that with a BMP serving as graph wall + some colored shape controls, reacting drag&drop events. Shape locations are stored as X,Y offsets, so this provided a way to plot manually entered values too. "Graph" (which is pure VFP) is refreshed as patient or visit changes. Currently we have one drawback with this approach : While it's fast and neat at "on screen" operations, reporting is a problem. We didn't have time to have a routine that would change frx on the fly for that purpose yet.
OLE automation with MSGraph or Excel is extremely slow for that purpose and doesn't provide a good scale that you would want it to be. Maybe flipper or Hallograms graphics server are good but I never had a chance to try.
