Keyword Parameters


Keywords


        /TO_DATA converts to data coordinates (def).
        /TO_DEVICE converts to device coordinates.
        /TO_NORMALIZED converts to normalized coordinates.

Outputs


      x2,y2 = same point in specified coordinate system. out

Common Blocks


Notes


      Notes: The plot window is the area defined by the axes.
        Normalized window coordinates are defined here to be
        linear from (0,0) at the lower left corner of the plot
        window, and (1,1) at the upper right.
        Useful for plot window related items such as legends.
        Normalized coordinates are really normalized device
        coordinates. Normalized window coordinates are missing
        from IDL's list of coordinate systems.
