Re: fill handle

As I understand the code of "legend.m" (lines 683-715), colored line is added
only for graphic objects of type "line". The easiest way, how to put colors
into the legend, seems to me in plot lines, create legend and overlay the
plot by patch. Something like that:

figure;
 x = 0:0.1:7;
 hold on
 h(1) = plot (x, sin(x));
 h(2) = plot(x,cos(x),'r');
 h(3) = plot(x, sin(x.^2/10),'g');
 h(4) = plot(x, cos(x.^2/10),'k');
 title ("Only the sin() objects have keylabels");
 legend (h([1, 3]), {"sin(x)", "sin(x^2/10)"}, "location", "southwest");

nplots = length(h);
 h(nplots+1) = fill (x, sin(x));
set(h(nplots+1),'facecolor','b');%,'edgecolor','b');
 h(nplots+2) = fill(x,cos(x));
set(h(nplots+2),'facecolor','r');%,'edgecolor','r');
 h(nplots+3) = fill(x, sin(x.^2/10));
set(h(nplots+3),'facecolor','g');%,'edgecolor','g');
 h(nplots+4) = fill(x, cos(x.^2/10));
set(h(nplots+4),'facecolor','k');%,'edgecolor','k');

Since the dafault "edgecolor" of patches is [0 0 0] ('k'), you can use
'edgecolor' option to ensure the correct overlay of ploted lines.
