legend code doesn't work
显示 更早的评论
x = -pi:pi/20:pi; y1 = sin(x); y2 = cos(x); plot(x,y1,x,y2) l = legend('sin(x)','cos(x)'); title(l,'My Legend Title')
This code doesn't display the legend title. I've tried various "h." things, title(legend,"..."), title(string,"...") etc and the best I can get is to display some text above the legend (through the top axis). Using Matlab 2013 at work.

You’re looking at the online documentation, that is for R2016a. In the documentation for the R2013a version of legend, the legend title property does not exist. If I remember correctly, it only became available in R2015b or R2016a.

x = -pi:pi/20:pi;
y1 = sin(x);
y2 = cos(x);
plot(x,y1,x,y2)
l = legend({'sin(x)','cos(x)'});
title(l,'My Legend Title')

A text object would work. Use the 'Position' property of the legend to calculate where to put the text object.
This will get you started:
x = -pi:pi/20:pi;
y1 = sin(x);
y2 = cos(x);
plot(x,y1,x,y2)
l = legend('sin(x)','cos(x)');
pos = get(l, 'Position');
ht = text(1,1, 'My Legend Title');
set(ht, 'Position',[pos(1)+pos(4)+1, pos(2)+pos(3)], 'VerticalAlignment','bottom', 'HorizontalAlignment','left')
You will obviously have to experiment to get the result you want with your plot. See the 'Position' property for details on the meaning of the values of the vector it returns. Note that you have to use initial (x,y) coordinates to plot the text, and they can be anything. Then use the 'Position' property to put it wherever you want it.
