      SET_ISOXY

Purpose

---

      Set data window with equal x & y scales. Covers at least given range

Category

---

Calling Sequence

---

      set_isoxy, xmn, xmx, ymn, ymx

Inputs

---

      xmn, xmx = desired min and max X. in
      ymn, ymx = desired min and max Y. in

Keywords

        CHARSIZE=csz Character size for axis labels (def=1).
        /LIST = list actual window that is set.
        XLOCK = position where position is one of
                'xmn' to extend window upward from the min x.
                'xmd' to extend window outward from the mid x.
                'xmx' to extend window downward from the max x.
        YLOCK = position where position is one of
                'ymn' to extend window upward from the min y.
                'ymd' to extend window outward from the mid y.
                'ymx' to extend window downward from the max y.
        NXRANGE = [nx_min, nx_max] sets x pos. in norm. coord.
                Min and max normalized x. Def = [0., 1.]
        NYRANGE = [ny_min, ny_max] sets y pos. in norm. coord.
                Min and max normalized y. Def = [0., 1.]
        LATITUDE=lat If given will set equal scaling based on
          given latitude. Expands X range by 1/cos(lat).
          Given latitudes not changed.

Notes

---

        Either xmn, xmx or ymn, ymx will be adjusted to force
        equal scaling in X and Y in the current screen window.
        At least the specified range will be covered in both X
        and Y, but a greater range will be covered in one.
        The window middle or corners may be fixed.
        set_isoxy,0,0,0,0 (or set_isoxy,0) resets autoscaling.

Modification History

---

      R. Sterner. 3 Sep, 1986.
      Johns Hopkins University Applied Physics Laboratory.
      RES 10 Sep, 1989 --- converted to SUN.
      R. Sterner, 8 Nov, 1991 --- fixed !x.style,!y.style to
      be reset on set_isoxy,0,0,0,0 and also allowed set_isoxy,0.
      R. Sterner, 21 Apr, 1992 --- added a plot statement to
      set scaling. No plot is output.
      R. Sterner, 1995 Jul 20 --- Added LATITUDE keyword.
      R. Sterner, 2010 Aug 08 --- Dropped chars in plotwin call.
