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.
