Create a custom legend
显示 更早的评论
Hello, I am struggling on how to create a custom label for a series of plots I am doing at the moment (I know how to change the right axis colour). Attached is a sample graph. What I want to do is extract the symbol shapes and give them their space on the legend with an attached lable i.e. X = O and Y = +, then remove those symbols from the rest of the lines, just displaying those colours.
If you need to code to work with, I can supply it will just take a while to trim the accompanying data down.
Could you offer some suggestions.
Thanks

You can add the legend manually and set the color and marker as per your own. See the below example for your reference.
x = linspace(0,pi);
figure
plot(x, cos(x),'r')
hold on
plot(x, sin(x),'b')
plot(x, sin(2*x),'m')
qw{1} = plot(nan, 'r-o');
qw{2} = plot(nan, 'b--');
qw{3} = plot(nan, 'm-d');
qw{4} = plot(nan, 'k-d'); % You can add an extra element too
legend([qw{:}], {'Data1','Data2','Data3', 'Data4'}, 'location', 'best')
