I have a pop-up menu (used GUIDE to create it.) which calls 3 functions

first function gives out a scatter plot of 14x14x14
second function plots a bar graph of 4x1 (dynamic data)
third function plots an Mx14 (dynamic data)

the thing all these use the same axes

axes(handles.someName).

I tried putting axes focus on every switch statement

function plot_options_popup_Callback(hObject, eventdata, handles)
str = get(hObject, 'String');
val = get(hObject, 'Value');
switch str{val};
    case 'Final Reading'
        YesNo = evalin('base','exist(''eeg_output_1d'',''var'')');
         axes(handles.eeg_final)
        if(YesNo == 1)
            plot(evalin('base','eeg_output_1d'));
        else
            return;
        end
    case 'Activation Plot'
        axes(handles.eeg_final)
        activation
    case 'Emotion State'
        axes(handles.eeg_final)
        emo_Callback
end

And when I change the option to a new one, the focus changes to the dynamic data which is continuously plotting.

Is there any way I could ask to GUI to stick to the thing what I want to and plot the dynamic data in the background?

Thanks in advance.

Yes, provide the axes-handle in the call to scatter3 ... instead of setting the current axes. Doc says:

    scatter3(ax,___) plots into the axes specified by ax instead of into the
    current axes (gca). The ax option can precede any of the input argument 
    combinations in the previous syntaxes.

and

    plot(ax,___) plots into the axes specified by ax instead of into 
    the current axes (gca). The option, ax can precede any of the input
    combinations in the previous syntaxes.

and

    bar(ax,___) plots into the axes specified by ax instead of into the
    current axes (gca). The option ax can precede any of the input 
    argument combinations in the previous syntaxes.
