how to save as .jpeg the result on axes including the colormap and color bar in GUI MATLAB

Hi,

I want to ask how can I save the pcolor data type I got on the axes including the colormap that I had changed. Also the color bar. I have read the matlab documentation if I'm using the copyobj function, it will not copy the figure properties. So far, Im using the code as follow:

% --- Executes on button press in save_select.
function save_select_Callback(hObject, eventdata, handles)
% hObject    handle to save_select (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

newfig1 = figure('Visible','off');
image=copyobj(handles.image_axes, newfig1);
saveas(image,'Tomogram.jpeg');
% Update handles structure
guidata(hObject, handles);

Its only save the pcolor image in jet (default) color.

This is the code for my pcolor image in the push button callback function for reference:

function lbp_select_Callback(hObject, eventdata, handles)
% hObject    handle to lbp_select (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

%each projection e1 till e16 from COMSOL in cell form :EachProj
    singleProj=load('EveryProjection.mat');
    SP=singleProj.EachProj;  %SP=single projection
% ---------- Dot product to get each pairing projection -----------
    i=1;
    for i=1:16                     %eliminate NAN values for each projection,e1 to e16
        e=SP{1,i};
        d=isnan(e);
        e(d)=0;
        SP{1,i}=e;
    end
    for i=1:16;                   
        m1=SP{1,i};
        for j=1:16
            m2=SP{1,j};
            c=m1.*m2;               % Do the element multiplication to get Ei,j
            E{i,j}=c;
        end
    end
%-------- Total Map/ Weight Balanced Map----------------------------------
    WBMap = zeros(128);
    for n=1:16;
        for m=1:16;
            WBMap = WBMap + E{n,m};          %%%Add coding for WBMap..x perlu load file WBMap yg buat cara panjang
        end
    end
%------------- Normalize each pair projection,NormEi,j--------------------
    for i=1:16;
        for j=1:16
             N{i,j} = E{i,j}./WBMap;
        end
    end
%%-------------------- LINEAR BACK PROJECTION(LBP)-----------------------
    disp('Displaying Tomogram...');
    Resolution = 128;  % --- IMAGE PIXEL SIZE

      sensorLoss=load('SensorLossE1110mm.mat');   % load sensor loss file
      Attenuate_xy=sensorLoss.SLe1110mm;

      DispMap = zeros(Resolution); %view = 1;      
              for Tx = 1:16;
                  for Rx = 1:16;
                          DispMap = DispMap + (Attenuate_xy(Rx,Tx) * N{Rx, Tx});  %%%coding for getting LBP
                   end
              end

% ----- DISPLAY TOMOGRAM RESULT--------------------------------------------
           pcolor(DispMap, 'Parent',handles.image_axes); 
           shading interp;
           getMax = max(DispMap(:));    % get max value in DispMap
           caxis([0, getMax])
           colormap (hot)               %  set color map to hot colour
           colorbar

% update data
guidata(hObject,handles);

Thus, could anybody guide me how to code so that I can save the pcolor image including the figure properties? Thank you.

I recommend that you install the export_fig File Exchange contribution, and invoke it on your (original) axes.
