Thread Subject: Bypass a Line Plotted in the Legend

Hello!)

I wonder how do I bypass a line plot out of multiple plots when putting the legend on a chart.

Suppose I have 10 vectors plotted on a chart. If I wish to make the legend display the info for only the first 3 time series and only for the last one...how do I do that?

leg = legend('one','two','three','four','five','six','seven','eight','nine','ten','Location','SouthEast');

Thanks!

Dima

You can select which lines to have in the legend:

legend(ph([1:3,end]),'1','2,'3','432')

THANKS!!! But what if I have a chart full of the various plot lies and markers and I need only to have some of these in the legend and those lines are all not plotted with one plot command....do you think it is possible??
thanks!)

Possible, sure...

You may have to do things like get() the properties of the lines in
question and set() the legend properties to match but if you save the
optional object handles from the legend call(s), you can modify the
properties at will or even add more lines, etc., etc., to the legend.
It (a legend, that is) is simply an axis object w/ lines, text, et al.

u can decide to use an empty strings where u don't want to label the line using legend.
e.g
legend('one','two','three','','','','','','last')

Certainly, but if the plot was created w/ multiple calls to plot, it's
possible (probable?) the line styles aren't going to be in synch
automagically...

Sure, as long as you keep track of your handles.


mylines = zeros(1, 5);
x = 0:0.1:2*pi;
axis([0 2*pi -1 1]);
hold on
listOfMarkers = {'o', 'x', '.', 's', 'd'};
listOfColors = 'rgbyc';
for k = 1:5
    mylines(k) = plot(x, sin(k*x), ...
        [listOfMarkers{k} '-'], ... % get the right marker and line style
        'Color', listOfColors(k)); % get the right color
end
legend(mylines([1 3 5]), 'sin(x)', 'sin(3*x)', 'sin(5*x)');
