      Initializes chart setup. Good for viewgraphs.


Calling Sequence



Keyword Parameters


        /HARD means plot on postscript printer (else screen).
        /LAND means use landscape mode (else portrait mode).
        UNITS=u Set plot units to 'inches' (def) or 'cm'.
        BPOSITION=p scalar or array giving list of outline
          offsets in UNITS from edge of page. Def=no outline.
        BTHICKNESS=t scalar or array giving outline thicknesses
          for each outline given in BPOS. Def=1.
        XOFFSET=xoff Set chart X offset in UNITS (def=0).
        YOFFSET=yoff Set chart Y offset in UNITS (def=0).
        /MOVE means just move origin. The only other keywords
          recognized with /MOVE are XOFFSET and YOFFSET.
          /MOVE should be used on the second and later calls to
          CHINIT to reposition the position of graphics.
        WINSIZE=sz Multiply default screen window size by this factor.

Output Keywords

        LAST=lst Highest available plot color, returned.
        FONT=f "!17" for screen, null string for /HARD.
          Put in front of first string printed to make
          device independent.
        FACTOR=f text size factor. 1 for /HARD, 0.68 for screen.
          Multiply text size by this for device independence.
        Any extra PSINIT keywords may be passed in.


Common Blocks



      Notes: Also erases to white and sets default plot
        color to black. All plot commands may then be
        given in units of inches or cm, whichever were set.
        Plot size:
          Portrait: 7.5 by 10 inches (360 by 480 on screen)
          Landscape: 9.5 by 7 inches (640 by 472 on screen)
        The screen view is not always close to the hard copy.
        Spaces are handled differently, and strings that fit
        for the hardcopy are sometimes too long on the screen.
