counting mouse clicks

Hi,

I want to get the number of clicks I made in a plot by using the buttondownfcn callback, but I don't know how to implement the count variable back to the main function:

function mousecount

count=0;
axes('buttondownfcn',{@click,count});

    function click(gcbo,eventdata,count)

    count=count+1;
    disp(count);

...?

Thanks for the help,

Julien

What I do is put an invisible text in the GUI ('visible','off') and set its string to 0 ('string','0').

Then in the buttondownfcn, get the number from the text, increment it, and put the new value in its place. That way I don't have to worry about globals and whatnot.

Maybe there' a simpler way but this is fast and it works nice.
