      Plot linear scales on the laser printer.


Calling Sequence

      make_ruler, file


Keyword Parameters


        PRINTER = postscript printer number (1=def or 2).
        /LIST to list control file lines as processed.
        /NOPLOT means just generate idl.ps but do not print it.


Common Blocks



        Control file format:
        * in column 1 for comment lines.
        CF = conversion_factor cm per UNIT
          Set a conv. fact. & unit name. Ex CF = 2.54 cm per inch.
          Must be number of cm per unit. Used for LENGTH & TICS.
          Default is cm.
        LENGTH = len
          Set ruler length in UNITS.
        XY = x, y
          Set ruler left side in cm from origin and draw line.
          Must do LENGTH before XY.
        LABELS = L1, L2, dL, y, s
          Sets up labels to be used on next TICS command.
          L1, L2, dL = label start, stop, step values.
          y = label position in cm above ruler line.
          s = label size.
        The following coord. are relative to ruler's left side.
        TICS = x1, x2, dx, dy
          Draws tic marks.
          x1, x2, and dx are tic x start, stop and step in UNITS.
          dy is tic length in cm. (Do labels first if labeled).
        TEXT = x, y, j, s, text string
          x,y = text position in cm relative to XY position.
          J = justification: L = left, C = centered, R = right.
          text string = text to print.
        TYPE = text string
          text string = message to display on terminal screen.
