legend1.m

Control line and text entries in a legend object, individually.

In the case of a multi-line plot where individual lines are created using a loop, one can easily control each line's properties, but it is less clear how to control the properties of each legend entry. This function gives control over some basic properties of individual legend entries: line color, text, text color, text font size.

Example:

nentries = 4;
colors = [0 0 1; 1 0 0; 0 1 0; 0 0 0]; % number of lines needs to match nentries
leglabels = {'Blue';'Red';'Green';'Black'}; % number of cells needs to match nentries

% create 4 curves
t = [1:100];
for ic=1:nentries
curve(ic,:) = rand(1,length(t)) + [t(1):t(end)]*0.1*ic;
end

% plot curves using for-end loop, insert legend
figure
for ic=1:nentries
plot(curve(ic,:),'Color',colors(ic,:))
hold on
end
