Question about creating a GUI

So I have the function for the mandelbrot set, and I also have a script to create a GUI. I cannot figure out how to get the image from the mandelbrot set to appear as the image in my GUI. Any help would be greatly appreciated.

Here is the script for the GUI:

function varargout = madelbrotset_gui(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @madelbrotset_gui_OpeningFcn, ...
                   'gui_OutputFcn',  @madelbrotset_gui_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end
function madelbrotset_gui_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);

function varargout = madelbrotset_gui_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;

function reset_button_Callback(hObject, eventdata, handles)
function zoom_out_button_Callback(hObject, eventdata, handles)
function zoom_in_button_Callback(hObject, eventdata, handles)
function pan_up_button_Callback(hObject, eventdata, handles)
function pan_left_button_Callback(hObject, eventdata, handles)
function pan_right_button_Callback(hObject, eventdata, handles)
function pan_down_button_Callback(hObject, eventdata, handles)

end
end
end
end
end
end
end
end
end
end

here is the script for mandelbrot set:

clc

xmin=-1.5;
xmax=1;
ymin=-1.5;
ymax=1.5;

map=mandelset(xmin,xmax,ymin,ymax);
figure(1)
imagesc(map)

colormap(jet)
while(1)
disp('click the top left')
[x1,y1]=ginput(1)
disp('now click the bottom right')
[x2,y2]=ginput(1)

yminnew=(ymax-ymin)/511*y1+ymin;
xminnew=(xmax-xmin)/511*x1+xmin;

ymaxnew=(ymax-ymin)/511*y2+ymin;
xmaxnew=(xmax-xmin)/511*x2+xmin;

map=mandelset(xminnew,xmaxnew,yminnew,ymaxnew);
figure(1);
imagesc(map)
colormap(jet)
xmin=xminnew;
xmax=xmaxnew;
ymin=yminnew;
ymax=ymaxnew;
end

You do not appear to have a button to start the drawing. When you create that button, in the callback for that button, place a line that just has on it the name of the script. For example if the script file name is "do_the_mandel.m" then a line in the callback would be

do_the_mandel

This will cause the image to appear as a figure in your GUI.

Note: if you do not want the script to erase everything else in your GUI, then precede the script name with "hold on", as in

hold on
do_the_mandel
