MATLAB: How to plot a graph in GUI by passing function

axeshandlesmatlab guipush button

Hi all,
I've created a GUI where it takes user input and calualtes and plots the results. All the calculation happens in a function called picrotor. This function takes input model and generates a plot.
I've created a push button which has a call back function defined as follows.
function [] = tb1_Callback(varargin)
axes(handles.haxes)
picrotor(model);
end
Now I want this graph to be plotted in the GUI where I defined it by its handle.
handles.haxes = axes('Units','Normalized','Position',[.05,.1,0.90,0.38],...
        'Parent',handles.f,'HandleVisibility','callback');
When I try to excecute the above GUI I get an error.
Reference to non-existent field 'haxes'.
Error in sample_gui/tb1_Callback (line 396)
axes(handles.haxes)
Error while evaluating UIControl Callback
Can someone help to fix this error. thanks in adance for your hints and suggestions. I just wanted to put the call the function and display the graph in GUI
My complete Code is as follows.
handles.f = figure('visible','off',...
    'Units','Normalized','Position',[25 25 1300 725],...
    'numbertitle','off','Name','Simple GUI);
handles.m = uimenu(handles.f,'Label','File');
aboutm = uimenu(handles.m,'Label','About','callback',@about);
docm = uimenu(handles.m,'Label','Documentation','callback',@documentation);
% loadm = uimenu(m,'Label','Load Data','callback','load');
exitm = uimenu(handles.m,'Label','Exit','callback',@exit);
    handles.tb1 = uicontrol(handles.f,'Style','pushbutton',...
                  'String','Prepare_geom',...
                  'Value',0,'Units','Normalized','Position',[0.45 .90 0.07,0.04],...
                  'Callback',{@tb1_Callback,handles});
handles.haxes = axes('Units','Normalized','Position',[.05,.1,0.90,0.38],...
        'Parent',handles.f,'HandleVisibility','callback'); 
     % Move the GUI to the center of the screen.
     movegui(handles.f,'center')
     % Make the GUI visible.
     handles.f.Visible = 'on';
%%call back function for Push button Prepar_Geom
function [] = tb1_Callback(varargin)
axes(handles.haxes)
picrotor(model)
end

Best Answer

You need to do the assignment to handles.haxes before the assignment to handles.tb1 . See the explanation in http://uk.mathworks.com/matlabcentral/answers/261050-reference-to-non-existent-field#answer_203806
