Simultanously plotting on two figures

Hey i've got problem.

In my GUI, i've got some buttons. On btn1 press figure is being created and plotting stars.

Here's my problem. I want to make on this press 2 figures with 2 simultanous plot. Or at least make a subplots on one figure.

How can I do it?

Here's my code for one plot:

if handles.StartbtnVal
        %Sprawdzanie guidata co jakis czas POPR
            guidata(figureHandle, handles)
            if j==0
                fprintf(s,'%c',znak);
                plotFigure = figure(2);
                axesHandle=axes();
                plotHandle=plot(axesHandle,NaN,NaN);
%                 plotFigureHandle=plot(axesHandle,NaN,NaN);
                axis([0 1000 -Inf Inf])
                
                drawnow
            else
            end
            if k==0;
                set(h.Editfield4,'String','Rysowanie');
                k=1;
            else
            end
                
            
            
            zm1=fgetl(s); %Pobranie aktualnej wartości z bufora
            j=j+1; %Iterator w prowadzony w celu odpowiedniego nawigowania pozycji w macierzy
            zm2=strip(zm1); %Polecenie usuwające wszelkie dotyczące znaku zakończenia bądź początku linii
            zm3=str2double(zm2); %Zamiana otrzymanej wartości z znakowej na liczbową
            DataBuff(1,j)=zm3; %Utworzenie wektora wartości otrzymanych z układu
            DrawBuff(1,j)=DataBuff(1,j);
            
            xfilt(1,j)=j;
           
%             figure(2)
            set(plotHandle,'YData',DrawBuff,'XData',x);
%             if mod(j,200) == 0
%             yfilt=filtfilt(1,1,DataBuff);
%             set(plotFigureHandle,'YData',DrawBuff,'XData',x);
%             drawnow
%             else
%             end
            
            
            drawnow

The callback for the button just does whatever it is you want done...what prevents doing so?

[Dominik Maly]

I want to do it in my while loop, obly detect the button push and I've done it. Now i've got problem with this plot.

[Walter Roberson]

Yes? Detect the button press and draw or update both plots.

You can specify two different handles for the two axes and while plotting specify the handle of the axis you want to plot on. The following command creates handles for the subplots:

Ax1 = subplot(1, 2, 1);
Ax2 = subplot(1, 2, 2);

To check the documentation for ‘subplot’ refer to the following link:

Implement the logic for plotting inside the callback function for the button.
