I waited a bit, was hoping that you'll be able to solve it on your own, and I still do. Just reorder your commands, if you want to plot with the checkbox, why the plot commands aren't in that function callback? Your range affects the plot, so you can use it within plot command.

Hint on the Button group: Value says if the button has been pressed or not, text is the title of the button.

app.ButtonGroup.SelectedObject
ToggleButton (button1) with properties:

       Value: 1
        Text: 'button1'
        Icon: ''
    Position: [12 41 100 22]

You can use the Text property and strcmpi to detect which button is pressed.

Even though this answer is not actually a proper answer, but I'll post it as one, as motivation to do the task on your own.

Thanks i really appreciate ur way to motivate for self Learning. yes u r exactly right that some command should be in checkbox call back... i tried it but for simplicity while asking the question i removed them... i tried them in checkbox call back

with if else that if app.UIButton.Value == 1 then do this etc.

or i tried if app.UIButton.Value 'on' then do this.

i will try again on ur guide line and inform update soon.

app.ButtonGroup.SelectedObject will return the handle for selected button, and app.ButtonGroup.SelectedObject.Value will always be 1, therefore it's not a good way to identify which button is pressed.

It's better if you use

if strcmpi(app.ButtonGroup.SelectedObject.Text, 'Range1')
%     plot
else
%     plot
end

Ok sir i m working on it and trying as it get resolved i will update U...

Hello Mario... i tried the following code with ifesle and switch case 
checkbox functionality has been achieved but now when i change 'Range'
plot does not updated... then i uncheck checkbox and select other range and again tick the Checkbox
    then it plot... means every time to change range of radiobutton
    i first have to switch off checkbox. i want when checkbox is tick
it should update plot everytime i change radiobutton of Range.. kindly guide 
    
 function PlotCheckBoxValueChanged(app, event)
        if value == true 
            if strcmpi(app.ButtonGroup.SelectedObject.Text, 'Range1')
               plot(app.UIAxes, app.a(1:3), app.b(1:3));
            else 
             strcmpi(app.ButtonGroup.SelectedObject.Text, 'Range2')
               plot(app.UIAxes, app.a(1:5), app.b(1:5));
            end
        else
            app.UIAxes.cla;
        end

[Mario Malic]

 function PlotCheckBoxValueChanged(app, event)
        if value == true 
            if strcmpi(app.ButtonGroup.SelectedObject.Text, 'Range1')
               plot(app.UIAxes, app.a(1:3), app.b(1:3));
            else 
%              strcmpi(app.ButtonGroup.SelectedObject.Text, 'Range2') % you have only two cases,
%                                                                       without strcmpi here
               plot(app.UIAxes, app.a(1:5), app.b(1:5));
            end
        else
            app.UIAxes.cla;
        end

This is great so far!

What if, you wrapped what you wrote in a function that you call each time any of these affecting components change? You don't have to change a lot, in the callback function PlotCheckBoxValueChanged(app, event), you obtain value, you just replace that variable with the property of the checkbox.

So create a helper function that will do this and call it whenever some of the components change.

after ur suggestion of "Helper Fucntion" what i understand through

Benito Sebastian tutorial on Appdesigner

https://www.youtube.com/watch?v=N3uy-X_EsEA&list=PLDzzooPYRJ_XNBUkbCkOM-TBWFeO5Ud4I&index=11

that instead of writing code again and again we should define that code in a function.

i also did so but that will shirink my code repetition, where should i define it for every change it should re-plot...

[Mario Malic]

Put everything into helper function.

function PlotGraph(app) 
    if app.PLotCheckBox.Value
        if strcmpi(app.ButtonGroup.SelectedObject.Text, 'Range1')
           plot(app.UIAxes, app.a(1:3), app.b(1:3));
        else 
           plot(app.UIAxes, app.a(1:5), app.b(1:5));
        end
    else
        app.UIAxes.cla;
    end
end

Dear Mario i m stuck in this issue from many days but i m unable to proceed further... in last days i tried to understand the builtin code of appdesigner especially "PulseGenerator" & "PatientsData"... learned many point but my basic objective is still not achieved, becasue these builin codes are much complex for me...

if u kindly share a demo or corrected file of my code i will be very thankfull.

[Mario Malic]

Don't get overwhelmed, nor discouraged, everyone is beginner at something, sometimes, so keep on learning and you'll get there.

I am not glad to send out a solution like this, but I hope for your next challenge you'll try harder solving the problem. It's clear that you can do it, just put a little bit more work into understanding the stuff and you can solve anything!

[taimour sadiq]

Yes i totally agree with u, thats why i studied the Bilt-in examples to analyze the way things get defined. Unfortunately i missed the right path.. and my next Target is to add a "Toggle Switch" functionality... i will try my level best to reach the Goal with self effort. Once again Thanks.

[taimour sadiq]

I successfully added Toggle swithc functionallity... once again thanks for ur support

[Mario Malic]

Well done!
