JMP user for years. All of the sudden the edit-copy graph procedure yeilds not just the graph but blank space beyond the right border and lower border so that the graph itself is only in the top left quarter of the pasted pic. I cannot find any preference that I changed.
Which platform are you copying the graph from? And what application are you pasting into? Does the app have multiple options, like Paste, Paste As Picture, Paste Special, etc?
Changed settings outside of JMP? Maybe windows->settings->display->100% scale or custom scale? There was an issue several releases back; I think it was fixed.
And our support team will need to know what you are doing to copy the graph (did you use the selection tool, right-click->copy, edit->copy, drag-and-drop, or something else).
You might also want to reset the windows-specific preferences in the preference panel.
