I want to change legend description for curve 3 and 4. Rather than V_x and V_y, I want to use u' (u dot) and v'(v dot). How can I edit the legend of the figure? I already have this figure.

Try to modify the following:

% generate some data

data = (1:10)' + randi([3 20], [1 4]);

plot(data)

legend(["1 $s=u$" "2 $s=v$" "3 $s=\dot{u}$" "4 $s=\dot{v}$"], "Interpreter", "latex")

I know this way of work. But here I have lots of figures that are already generated, I do not want to generate these figures again, just I want to change these 2 description in the legand( manually). Otherwise, it will take too much time. Is it possible to change in the legend only?

Thanks for the reply.
