How do i know which checkbox was chosen and from which figure in a subplot of figures ?

I have two figures and each figure has subplots of two random signals .i have added a check box near each corresponding plot .

Now for the code to plot these graphs and which box was clicked, i have created a function 'checkbox_plot'(whose code i have attached).

This function tells me which box was chosen in a variable 'M' but it gives me information for only one figure ( not all together) .i.e.i am not able to differentiate to which checkbox from which plot was chosen.

My question is how do i store which checkbbox was chosen from the figure and simultaneously knowing which figure was selected 'Figure 1' or Figure 2' and so on....

Can you also tell me how to store the names of the plot also along with the checkbox selection ?

Codes are attached below along with the plot the signals

Any help will be appreciated.Thank you

sachin - do you want to know which figure the selected (or unselected) checkbox belongs to, or which subplot of which figure? You kind of know which subplot (your M?) but as for the figure, if you do

hFig = get(hObj, 'Parent');

then this will give you the handle to the figure that the checkbox belongs to (at least on my version of MATLAB...this may have changed for yours or you can make an equivalent call). Is having the handle sufficient?

Thak you Geoff for your response .So this line whihc you said will get me my figure number.So where do i put it .Inside the subfunction or the parent function .

Thank you in advance

Sachin - you can put this line of code in the callback where hObj is defined. And this will give you the handle to the figure...but not necessarily the figure number...
