add a function to be executed for a subplot ButtonDownFcn event

I need to add a function to the ButtonDownFcn event of a subplot which will open another figure.

I am using:

subplot(3,4,1,'ButtonDownFcn',{@mySubplotCallback, arrData});

and

function mySubplotCallback(src,eventdata,x)
figure (100)
pie(x);
end

Where am going wrong here?

Nothing is wrong. You just need to move your cursor over the subplot and then press button down. It worked for me as I tried.

subplot(3,4,1,'ButtonDownFcn',{@mySubplotCallback, rand(5,1)})

I see the problem. If the following two lines are executed, it looks like the pie chart blocked the subplot axes such that the button down function callback is not triggered.

subplot(3,4,1,'ButtonDownFcn',{@mySubplotCallback, rand(5,1)});
pie(rand(5,1))

One solution is to do this:

subplot(3,4,1,'ButtonDownFcn',{@mySubplotCallback, rand(5,1)});
p=pie(rand(5,1));
set(p,'ButtonDownFcn',{@mySubplotCallback, rand(5,1)});

Yes, it works, now when I add a pie chart on the subplot, it no longer works subplot(3,4,1,'ButtonDownFcn',{@mySubplotCallback, arrData}); pie(arrData);
