"select curve?"
Well, yes, in a sense. When you plot the curve, you can supply a ButtonDownFcn, so that when you click on the curve, will initiate whatever code you write. In a very simple form, I did this:
mycallback = @(varargin) disp("yeah? what do ya want?");
plot(1:5,rand(1,5),buttondownfcn = mycallback)
Now, when I click on the curve, I see this grumpy response:
yeah? what do ya want?
But if I click on an empty part of the figure, I see nothing. The callback is only initiated when I click right on the curve.
You can be far more creative than what I did of course.
