"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.

Thanks.. To be more precise I want to change the transparent color to all the other equities (and in the one I touch I keep the color) Can you give me an example how to do it?
