To save an image of a graph you can use the function GetCtrlBitmap from the User Interface library, then the function SaveBitmapToFile from the Programmer's Toolbox (cvi\toolslib\toolbox\toolbox.fp). That will save a BMP file of the graph. You can also get a bitmap of a panel with GetPanelDisplayBitmap.
