Uses abbreviations for the options ## to avoid overrunning gnuplot's command line buffer unnecessarily. ## ## @var{opt} can currently be some combination of the following: ## ## @table @code ## @item "-" ## For lines plot style (default). ## ## @item "." ## For dots plot style. ## ## @item "@@" ## For points plot style. ## ## @item "-@@" ## For linespoints plot style. ## ## @item "^" ## For impulses plot style. ## ## @item "L" ## For steps plot style. ## ## @item "#" ## For boxes plot style. ## ## @item "~" ## For yerrorbars plot style. ## ## @item ">" ## For xerrorbars plot style. ## ## @item "~>" ## For xyerrorbars plot style. ## ## @item "#~" ## For boxerrorbars plot style. ## ## @item "#~>" ## For boxxyerrorbars plot style. ## ## @item "n" ## With @code{n} in 1-6 (wraps at 8), plot color ## ## @item "nm" ## With @code{m} in 1-6 (wraps at 6), point style (only valid for @code{"@@"} or ## @code{"-@@"}) ## ## @item @var{c} ## Where @var{c} is one of @code{"r"}, @code{"g"}, @code{"b"}, @code{"m"}, ## @code{"c"}, or @code{"w"} colors. ## ## @item ";title;" ## Here @code{"title"} is the label for the key. ## ## @item + ## @itemx * ## @itemx o ## @itemx x ## Used in combination with the points or linespoints styles, set the point ## style. ## @end table ## ## The legend may be fixed to include the name of the variable ## plotted in some future version of Octave. ## ## The colors, line styles, and point styles have the following ## meanings for X11 and Postscript terminals under Gnuplot 3.6. ## ## @example ## Number ------ Color ------- Line Style ---- Points Style ---- ## x11 postscript postscript x11 postscript ## ===================================================================== ## 1 red green solid "o" "+" ## 2 green blue long dash "+" "x" ## 3 blue red short dash square "*" ## 4 magenta magenta dotted "x" open square ## 5 cyan cyan dot long dash triangle filled square ## 6 brown yellow dot short dash "*" "o" ## @end example ## @end deftypefn ## ## @seealso{__pltopt1__} ## Author: jwe function fmt = __pltopt__ (caller, opt) if (! ischar (opt)) usage ("__pltopt__ (caller, opt)"); endif nr = rows (opt); fmt = ""; for i = 1:nr t = __pltopt1__ (caller, deblank (opt(i,:))); fmt(i,1:length(t)) = t; endfor endfunction
