Changing Plot Over Selection Button in a Buttongroup

Hi, Community

Actually, my question is maybe a common / basic for a GUI MATLAB Programmer, because i just want to ask about how to change my Plotting Graph right after i click a (single) Button in my GroupButton Panel. So i have this Time Serise Graph in my GUI :

And the code of that Graph is from this one (A Press Button Callback) :

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

........................ Stuffs
combowaktus_convs = vertcat(waktucombo_gabung{:}); %Time Series Data for X Plot    
ff = get(handles.compmagz,'SelectedObject');
    
    switch ff
        case handles.xcomp
            graph_ori_s = x_combi; %Magnetic Data for Y Plot  
            y_lbl_s = 'Variasi Medan Magnet Komponen X (Nanotesla / nT)';
        case handles.ycomp
            graph_ori_s = y_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Komponen Y (Nanotesla / nT)';
        case handles.zcomp
            graph_ori_s = z_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Vertical / Z (Nanotesla / nT)';
        case handles.hcomp
            graph_ori_s = hcalc_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Horizontal / H (Nanotesla / nT)';
        case handles.fcomp
            graph_ori_s = fcalc_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Total / F (Nanotesla / nT)';
        otherwise
    end

axes(handles.grafik);
plottings=plot(combowaktus_convs, graph_ori_s,'color', 'w','Parent',handles.grafik);
title(sprintf('Data Ekstraksi Magnet (%s) %s Stasiun %s', tipe_ekstrak1, mr_c, stasiun_ekstrak1), 'Color', 'y', 'fontsize', 11.5, 'fontweight','bold', 'Parent',handles.grafik);
xlabel(xlbl, 'Color', 'y','fontweight','bold','fontsize',10,'Parent',handles.grafik);
ylabel(y_lbl_s, 'Color', 'y','fontweight','bold','fontsize',10,'Parent',handles.grafik);

set(plottings,'LineWidth',1.1, 'Parent',handles.grafik);
set(handles.grafik,'Color',[1 0.96 0.9],...
    'XGrid','on',...
    'YGrid','on',...
    'NextPlot','add');
storage = [combowaktus_convs(:) graph_ori_s(:)]; %% This is my Data Storage for X and Y Plot Data
set(handles.grafik, 'Userdata', storage); %% This is my Data Storage for X and Y Plot Data

And here is my RadioButton SelectionChange code :

function compmagz_SelectionChangedFcn(hObject, eventdata, handles)
% hObject    handle to the selected object in compmagz
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
selected_obj = hObject;
switch get(selected_obj, 'Tag')
    case 'xcomp'
        handles.value = 1;
        answers = get(selected_obj, 'Value');
    case 'ycomp'
        handles.value = 2;
        answers = get(selected_obj, 'Value');
    case 'zcomp'
        handles.value = 3;
        answers = get(selected_obj, 'Value');
    case 'hcomp'
        handles.value = 4;
        answers = get(selected_obj, 'Value');
    case 'fcomp'
        handles.value = 5;
        answers = get(selected_obj, 'Value');
    otherwise
        handles.value = 0;
        answers = 0;
end

I had created the Selection change Code without knowing how to handle the plot from my data storage. My question is, how to create a code to let me change the plot automatically right after i click one of Radio Button in my RadioButton Group? It should be from compmagz_SelectionChangedFcn function, right?

At the above picture, i want to plot Z magnetic component right after i clicked Kom.Z Button, so in this case the graph would include X-plot as combowaktus_convs (Time series) and the Y-Plot as graph_ori_s (z_combi ) .

Noted : I had been attached my GUI files (m.file and fig.file) and also magnetic data for it.

So anyone, would you lend me a hand for the solution of my question.... Thank you very much, Everyone.... /.\ /.\ /.\

I don't think this is the best way, but you'd do

function compmagz_SelectionChangedFcn(hObject, eventdata, handles)
% hObject    handle to the selected object in compmagz
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
selected_obj = hObject;
handles.xcomp = 0;
handles.ycomp = 0;
handles.zcomp = 0;
handles.hcomp = 0;
handles.fcomp = 0;
switch get(selected_obj, 'Tag')
    case 'xcomp'
        handles.xcomp = 1;
    case 'ycomp'
        handles.ycomp = 1;
    case 'zcomp'
        handles.zcomp = 1;
    case 'hcomp'
        handles.hcomp = 1;
    case 'fcomp'
        handles.fcomp = 1;
    otherwise
        handles.value = 0;
        answers = 0;
end
% Now call the plotting function from inside the
% compmagz_SelectionChangedFcn() function
loadplot_Callback(hObject, eventdata, handles);

What I'd do instead is to just call the plotting function and have the checking of what radio button is selected done inside of that.

Like

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

........................ Stuffs
combowaktus_convs = vertcat(waktucombo_gabung{:}); %Time Series Data for X Plot    
% Check the Value property of the individual radio buttons.
if handles.xcomp.Value
        graph_ori_s = x_combi; %Magnetic Data for Y Plot  
        y_lbl_s = 'Variasi Medan Magnet Komponen X (Nanotesla / nT)';
elseif handles.ycomp.Value
        graph_ori_s = y_combi; %Magnetic Data for Y Plot 
        y_lbl_s = 'Variasi Medan Magnet Komponen Y (Nanotesla / nT)';
elseif handles.zcomp.Value
        graph_ori_s = z_combi; %Magnetic Data for Y Plot 
        y_lbl_s = 'Variasi Medan Magnet Vertical / Z (Nanotesla / nT)';
elseif handles.hcomp.Value
        graph_ori_s = hcalc_combi; %Magnetic Data for Y Plot 
        y_lbl_s = 'Variasi Medan Magnet Horizontal / H (Nanotesla / nT)';
elseif handles.fcomp.Value
        graph_ori_s = fcalc_combi; %Magnetic Data for Y Plot 
        y_lbl_s = 'Variasi Medan Magnet Total / F (Nanotesla / nT)';
else
end

axes(handles.grafik);
plottings=plot(combowaktus_convs, graph_ori_s,'color', 'w','Parent',handles.grafik);
title(sprintf('Data Ekstraksi Magnet (%s) %s Stasiun %s', tipe_ekstrak1, mr_c, stasiun_ekstrak1), 'Color', 'y', 'fontsize', 11.5, 'fontweight','bold', 'Parent',handles.grafik);
xlabel(xlbl, 'Color', 'y','fontweight','bold','fontsize',10,'Parent',handles.grafik);
ylabel(y_lbl_s, 'Color', 'y','fontweight','bold','fontsize',10,'Parent',handles.grafik);

set(plottings,'LineWidth',1.1, 'Parent',handles.grafik);
set(handles.grafik,'Color',[1 0.96 0.9],...
    'XGrid','on',...
    'YGrid','on',...
    'NextPlot','add');
storage = [combowaktus_convs(:) graph_ori_s(:)]; %% This is my Data Storage for X and Y Plot Data
set(handles.grafik, 'Userdata', storage); %% This is my Data Storage for X and Y Plot Data

And the simplifed group selection would be simply one single line to call the loadplot_Callback() function.

function compmagz_SelectionChangedFcn(hObject, eventdata, handles)
% Now call the plotting function from inside the
% compmagz_SelectionChangedFcn() function
loadplot_Callback(hObject, eventdata, handles);

There is no need to store xcomp, ycomp, etc. as new, additional fields of handles. They're already there. Just check the "Value" property of the control at the time you actually need to check it.

[Tyann Hardyn]

Ive already tried it, Sir. And it still get an error like this :

Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)interp('compmagz_SelectionChangedFcn',get(hObject,'SelectedObject'),eventdata,guidata(get(hObject,'SelectedObject'))) 
Error while evaluating ButtonGroup SelectionChangedFcn.

Unrecognized function or variable 'graph_ori_s'.

Error in interp>loadplot_Callback (line 405)
    plottings=plot(combowaktus_convs, graph_ori_s,'color', 'w','Parent',handles.grafik);

It looks like it become Not Recognized graph_ori_s variable from :

ff = get(handles.compmagz,'SelectedObject');
    
    switch ff
        case handles.xcomp
            graph_ori_s = x_combi; %Magnetic Data for Y Plot  
            y_lbl_s = 'Variasi Medan Magnet Komponen X (Nanotesla / nT)';
        case handles.ycomp
            graph_ori_s = y_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Komponen Y (Nanotesla / nT)';
        case handles.zcomp
            graph_ori_s = z_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Vertical / Z (Nanotesla / nT)';
        case handles.hcomp
            graph_ori_s = hcalc_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Horizontal / H (Nanotesla / nT)';
        case handles.fcomp
            graph_ori_s = fcalc_combi; %Magnetic Data for Y Plot 
            y_lbl_s = 'Variasi Medan Magnet Total / F (Nanotesla / nT)';
        otherwise
    end

In the loadplot_Callback(hObject, eventdata, handles) function....

[Image Analyst]

That's a completely different error. It doesn't know what graph_ori_s is because you have not defined it, or if you did, it's not in scope in this callback function.

Attach your m-file and fig file and any files needed to launch the program and I'll see if I can fix it.

[Tyann Hardyn]

Alright, Sir Image Analyst. I had been already attached my GUI files in this post and also all of data sample for plotting at the GUI code. Please help me, Sir. Thank you very much /.\ /.\ /.\

[Image Analyst]

OK. working on it now... stay tuned. Give me a few hours.

[Image Analyst]

Try the attached.

[Tyann Hardyn]

OMG, it was so fast, Sir.... Alright, i ll try it with pleasure....

[Image Analyst]

So, did it work?

[Tyann Hardyn]

It works, Sir. Great !

And im still learning to let your code to be merged in my whole program.

I never thought that the result is so Great, because my program before didnt let me to plot when the Listbox is pressed. The listbox of my program before is just for showing what and how many files that was selected.

It was awesome, and im still learning by your Program. ...

And, OMG, it was me in the Image Photos, hhaa. You re the True Image Analyst, haha^^

Thank you so much, Sir !!

[Image Analyst]

@Tyann Hardyn, glad I could help. If you like it, could you click the "Accept this answer" link? Thanks in advance.

[Tyann Hardyn]

Sir, Image Analyst. Hi Sir, emmm, Excuse me... But how if the listbox files i handle is just from the specific selected files? Because i noticed, that you had changed a slight method to load the listbox file(s), it was from manual selection files to become automatically detecting files inside a folder. Here is the picture i mentioned :

I just want to load the selection files just like the GUI code i attached, SIr.... So then the step will become :

1) load file(s) by selecting it manually to the listbox

2) we can process the file(s) (plot a graph) based on the selected file(s) in the listbox

3) We can plot another parameter by selecting Radiobutton

Thats all, Sir. Please, help me..... Thank you so much...

[Image Analyst]

Not sure what you want. Yes I load the listbox with all the files in the folder you selected. Then in the callback I automatically plot it. If you don't want anything to happen when you click an item in the listbox, you can get rid of the listbox call back function contents.

If you don't want a listbox and want the user to manually browse to it, you can do it like you were, though I think this is not very user friendly compared to just clicking on the filename in the listbox.

If you want the items to be listed in the listbox but don't want them to be automatically plotted, you can get rid of the plotting and have the user push a button.

What I often do is to have a checkbox that says "Auto-plot file" and then if checked, do the plot, but if unchecked, skip the plot.

Your step 2 is already done. Clicking on a filename automatically reads it in and plots it but like I said, you can change it to a more manual process if you want.

Your step 3 is already done. If you click a radio button, it updates the plot as soon as you click it.

Please explain in more detail exactly how you want it to work and upload the .m and .fig file (current/latest version).
