64 bit ActiveX Chart control
-
I am looking for a charting control to be used in an MFC application that we want to convert to 64 bit. We have used ComponentOne Chart for years, but they do not have a 64-bit activeX version, and it looks like they aren't going to develop one. Requirements include: * 64-bit activeX control * line charts * what excel would call scatter charts -- chart a line based on X and Y data where the X values are not evenly spaced. * surface charts, where the input is Z values at X and Y coordinates, and the control charts a wire-mesh, or a smooth surface. * contour charts, where again the input is Z values at X and Y coordinates, and the control charts contour lines, or contour color bands. * can zoom in on the data, either through user interaction, or programatically. * ability to handle large amounts of data. In the 3D surface charts, we would like to be able to handle at least 100x100 so 10,000 data points, and 500x500 (250,000 data points) would be nice. I have searched and haven't found anything that meets our needs. Any suggestions? TIA, Don
