I try to plot a histogram in Matlab Gui using axis control. But nothing change after running code below:

Code:

 handles.hist=hist(sort(averSpectrum),500);
 guidata(hObject, handles);

What is wrong I have tried almost every combination.

在 MATLAB Online 中打开

[counts, binCenters] = hist(sort(averSpectrum),500);
axes(handles.whateverAxesYouWant);
bar(binCenters, counts, 'BarWidth', 1);
grid on;

I have still problem with some error :

 ??? Error using ==> axes
 *Invalid object handle*
 Error in ==> program>resamp_Callback at 92
 axes(handles.hist);
 Error in ==> gui_mainfcn at 96
        feval(varargin{:});
 Error in ==> program at 42
    gui_mainfcn(gui_State, varargin{:});
 Error in ==>
 @(hObject,eventdata)program('resamp_Callback',hObject,eventdata,guidata(hObject))
 ??? Error while evaluating uicontrol Callback

My whole code in this callback :

 function resamp_Callback(hObject, eventdata, handles)
 % hObject    handle to resamp (see GCBO)
 % eventdata  reserved - to be defined in a future version of MATLAB
 % handles    structure with handles and user data (see GUIDATA)
 [minR,maxR,list,count,averSpectrum,averIntensity,setX,df]=resampling(10);
 handles.averSpec=plot(setX,averSpectrum);
 set(handles.vmin,'String',num2str(min(setX)));
 set(handles.vmax,'String',num2str(max(setX)));
 set(handles.myList, 'String', cellstr(num2str(setX(:))));
 counts, binCenters] = hist(sort(averSpectrum),500);
 axes(handles.hist);
  bar(binCenters, counts, 'BarWidth', 1);
 grid on;
 guidata(hObject, handles);

Double click the axes where you want to display the histogram to bring up the property inspector. Then look at the "tag" property. What does it say? Is the value of the tag property "hist" or is it some other word?

Then look up this link: http://blogs.mathworks.com/videos/category/gui-or-guide/ and this one: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/
