Plot legend for loop
显示 更早的评论
I want to have a consolidated plot generated from "for loop" with legend for only first and last value of the variable.
My code would look like this
hold on
for i = 0.1:0.001:1
plot(i,cos(i))
end
hold off
My function is different than cos(i), the problem that I have is that I want to display legend for only i = 0.1 and i = 1, which I couldn't. Or is there any way I could indicate that the line belongs to i =0.1 and i=1? Any reference or help is highly appreciated.
thanks

Legend belongs to a specific line, not just one point on the line. Can you show us an example of what is your required output?

Are you looking to labelling the point?
doc text % ?

You can try assign each line with a handle by
hold on
iHandler = 1;
for i = 0.1:0.001:1
iHandler = plot(i,cos(i));
iHanlder = iHanlder + 1;
end
hold off
After that, you can use legend([1 whateverNumCorrespondingTo1], {'your legend'}).
Or you can set DisplayName property in plot function that only has value when i = 0.1 or 1.
