How can i plot on axes on a GUI when click on a push button on another GUI?

Hello!

i have two GUIs with an axes on GUI1 and a push button on GUI2. Now, i want to plot in axes on GUI1 by cliking in the button on GUI2 with the informations in the GUI2

how can i do ?????

I tried a code below: (in function_callback of push button on GUI2)

findaxes = findobj('Tag','modelspace') % modelspace is Tag property of axes on GUI1
plot(findaxes,data from GUI2)  

But, matlab return:

findaxes = 

  0x0 empty GraphicsPlaceholder array.

Error using plot
Vectors must be the same length.

Error in inputpoint>ok_Callback (line 131)
plot(findaxes,rand(1,20))

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in inputpoint (line 42)
    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)inputpoint('ok_Callback',hObject,eventdata,guidata(hObject))
