Edit linestyles of plot legends

Simple fix for adding markers to plot legend lines.

Description

If a plot is sampled very densely, and one wants to add markers to the plot, this can be done by plotting two lines on top of each other. One being the smooth line, the other being a down-sampled version with the markers only (e.g. diamonds, squares)

Now, the above is fine as long as we don't need a plot legend, since the legend function will scan for all lines, and what we have is a combination.

This simple script is a work-around to the problem. There is also an example file included showing how to use the function.

• MATLAB release: MATLAB 7.5 (R2007b)
• Other Files: legendlinestyles.m, ; legendlinestyles_test.m

very good! please also add color change:

%define colors
colors={'k',[0 0 1]};

%in your function:
%...
if ischar(colors{m})==1
        set(lines(k),'color',char(colors{m}));
else
        set(lines(k),'color',colors{m});
end
%...

Thanks. I had this problem and your code worked for me. Another code 'hack legend' also works the same way
