Hi,

I work with a GUI includes axes ( matlab2016a ),

I already activated the datacursor in gui side (from toolbar),

I can see coordinates when I click to graph,

But I want to get coordinates of mouse click, I mean reading the values, x and y,

I try with cp = get(gca,'CurrentPoint');

Does not work.

Can anyone help?

Regards.

What aspect of get( gca, 'CurrentPoint' ) 'doesn't work'?

You can use one of these commands to read the data on mouse click.

   [x, y] = getpts(fig) 
        or
    [x, y] = getpts(ax)

You can use 'enter' after the selection of required number of data points.

Thanks, I get it.

Is it possible using 'enter' by commands? I mean via code?
