How to pass parameters between local functions of uicontrol, pushbutton?

I am writing a program in which a figure is created. I have added 3 uicontrol pushbuttons. the idea is this: user can select the desired part of data by one of pushbuttons and save the selected part by another pushbutton. if he/she doesn't want to save is able to cancel the selected part by the other pushbutton,'cancel'.

My problem is that I can not pass parameters from one local function of pushbutton to the other one I mean matlab forgets the variables created in one local function when it goes out of it. what can I do?

How can I share data between callback functions in my GUI(s)? Make use of setappdata, getappdata or global variables as shown.

thank you for your help but it didn't work again. you know the problem is that local functions of uicontrol work completely independent and at least I can not pass parameters between them. what I did for solving this problem is to get the handles of the lines (which are drawn as the data is selected) and delete them!!! perhaps not a good solution but it works. I think that as much as I know we cannot pass parameters betwwen these local functions unless we save them in a .mat file.
