range |
                 range, ymin, ymax

         sets the y-axis plot limits in the current coordinate system to
         YMIN, YMAX, which may be nil or omitted to leave the corresponding
         limit unchanged, a number to fix the corresponding limit to a
         specified value, or the string "e" to make the corresponding limit
         take on the extreme value of the currently displayed data.
         Use    limits, xmin, xmin
         to accomplish the same function for the x-axis plot limits.

    interpreted function, defined at i0/graph.i   line 716

raw_style |
                 raw_style: get_style, set_style, read_style, write_style
                 #include "style.i"

         alternatives to the style= keyword of the window command which
         allow the interpreter to set or get all the details of the
         window style.  Include "style.i" and read the help for get_style.

    builtin function, documented at i0/graph.i   line 1377
rays |
                 rays=   plotting keyword

         selects unadorned lines (rays=0), or lines with occasional ray
         arrows (rays=1).  Ignored if type is "none".  The spacing and phase
         of the occasional arrows can be altered using the rspace and rphase
         keywords; the shape of the arrowhead can be modified using the
         arroww and arrowl keywords.
       PLOTTING COMMANDS: plg, plc

    keyword,  defined at i0/graph.i   line 922
SEE ALSO: | type, width, color, marker, marks, rspace, rphase, arroww, arrowl
redraw |
                 redraw

         redraws the X window associated with the current graphics window.

    builtin function, documented at i0/graph.i   line 221
SEE ALSO: | window, fma, hcp, plg
region |
                 region=   plotting keyword

         selects the part of mesh to consider.  The region should match one
         of the numbers in the IREG array.  Putting region=0 (the default)
         means to plot the entire mesh, that is, everything EXCEPT region
         zero (non-existent zones).  Any other number means to plot only
         the specified region number; region=3 would plot region 3 only.
       PLOTTING COMMANDS: plm, plc, plv, plf

    keyword,  defined at i0/graph.i   line 1019
rgb_read |
                 rgb = rgb_read()
              or rgb = rgb_read(n)

         Read contents of current graphics window, or of graphics window N.
         RGB is a 3xNXxNY array of char where NXxNY is the current shape of
         the window in pixels.  RGB(1,,) is the red component, RGB(2,,) is
         the green component, and RGB(3,,) is the blue component, with 0
         black and 255 full intensity.  RGB(,,1) is the top row of the
         window, RGB(,,2) the second row, and so on to RGB(,,0), which is
         the bottom row.  (So RGB(,,::-1) to pli redraws a copy.)

    builtin function, documented at i0/graph.i   line 1314
rphase |
     rphase

    keyword,  defined at i0/graph.i   line 934
SEE | rspace
rspace |
                 rspace=   plotting keyword
              or rphase=   plotting keyword
              or arroww=   plotting keyword
              or arrowl=   plotting keyword

         selects the spacing, phase, and size of occasional ray arrows
         placed along polylines.  The spacing and phase are in NDC units
         (0.0013 NDC equals 1.0 point); the default rspace is 0.13, and
         the default rphase is 0.11375, but rphase is automatically
         incremented for successive curves on a single plot.
         The arrowhead width, arroww, and arrowhead length, arrowl are
         in relative units, defaulting to 1.0, which translates to an
         arrowhead 10 points long and 4 points in half-width.
