Dear all,
I am wondering if it is possible to:
1. change the order of the curves in the legend after they have been plotted.
2. Indicate only the characteristics of a group of curves. For example, if I have 4 curves with different colors but two of them have circles and two of them have squares, I want a legend which only shows the circle to group the first 2 curves and the square to group the others.
Thank you in advance for your help! :)

"change the order of the curves in the legend after they have been plotted"
The MATLAB code works sequentially. It is better to understand the requirements, then plot the curves according to the requirements.

(1) Imagine that you've got 3 plots:
yourplots = get(gca, 'children');
legend(yourplots([3 1 2]), {'3', '1', '2'});
you can specify the legend as above.
(2) how about using "hggroup" - you can group up some lines and provide the similar attributes
