Missing subplots inside a panel

I am trying to draw some interfaces programmatically. I am blocked with a problem that I cannot fix. I need to draw several graphs with the characteristic that the number of subplots is variable and they have to be inserted inside a panel that uses a slider to enable the visualization of all of them. The problem is that although the drawing zone size is calculated correctly, it does not draw after position 0.63 (being 1 the end of the panel). Here is the code of my .m file and the images of the obtained result:

<<

function SliderHor()

    % make the GUI fullscreen
    set(0,'units','pixels');
    pix = get(0,'screensize');
    w = pix(3);
    h = pix(4);
    set(gcf,'units','pixels','outerposition',[50 50 w-100 h-100]);
    set(gcf, 'NumberTitle', 'off', 'Name','Graphs', 'MenuBar', 'none', 'ToolBar', 'none');

    %Create the panel and the slider
    panel1 = uipanel('Position',[0.05 0.15 0.9 0.8]);
    panel2 = uipanel('Parent',panel1, 'Position',[0 0 2 1]);
     s = uicontrol('Style','Slider','Parent',panel1,'Units','normalized',...
        'Position',[0 0 1 0.05],'Value',0,'Callback',{@slider_callback1,panel2});

    % paint the graphs
    nReplicas = 10;
    replicaW = 1/nReplicas;

     for j=1:nReplicas
         % data
         x  = 0: .1 : 2*pi;
         y1 = cos(x);
         y2 = sin(x);

         % Draw each cell data
         xpos = (j-1)*replicaW + replicaW/6;
         subplot(1,2*nReplicas,(2*j)-1,'Parent',panel2,'Position',[xpos,0.2,replicaW/3,0.6]);
         % Plot y1 vs. x (blue, solid) and y2 vs. x (red, dashed)
         plot(x, y1, 'bs');        
         % Add title and axis labels
         xlabel('angle')
         ylabel('cos(x)')
         title(sprintf('Replica %d',j))  

         xpos2 = (j-1)*replicaW + replicaW/6 + replicaW/3;
         subplot(1,2*nReplicas,2*j,'Parent',panel2,'Position',[xpos2,0.2,replicaW/3,0.6]);        
         plot(x,y2,'r-','LineWidth',2);
         xlabel('angle')
         ylabel('sin(x)')
         title(sprintf('Replica %d',j))
     end

    % callback function
    function slider_callback1(src,eventdata,arg1)
    val = get(src,'Value');
    set(arg1,'Position',[-val 0 2 1])
    end

end

Works fine for me using axes rather than subplot in R2015a too so doesn't look like a version issue.

[Elisa Prada]

Ok, I do not understand it. Could you please include the .m you are using?

[Elisa Prada]

I have removed the screensize part and it works, I can see all the graphs . Thanks a lot for your help!

I very rarely use subplot and that behaviour I cannot understand on stepping through. However, you do not need to complicate issues by using subplot, just create axes and it seems to work fine - i.e.

Replace this:

    subplot(1,2*nReplicas,(2*j)-1,'Parent',panel2,'Position',[xpos,0.2,replicaW/3,0.6]);

with this:

axes( 'Parent',panel2,'Position',[xpos,0.2,replicaW/3,0.6] );

and the equivalent for the 2nd plot of a pair too.

I would recommend keeping the axes handle you create and referring to it explicitly for plotting though anyway - e.g.

hAxes = axes( 'Parent',panel2,'Position',[xpos,0.2,replicaW/3,0.6] );
plot(hAxes, x, y1, 'bs');        
% Add title and axis labels
xlabel(hAxes, 'angle')
ylabel(hAxes, 'cos(x)')
title(hAxes, sprintf('Replica %d',j))

I have tried with axes too but it happens the same. Have you run it? Can you see all the graphs? I have just tried it again and I can only see until "Replica 6".

[Adam]

I could see all the graphs when I ran it, but only when using axes. Using subplot the 7th and onwards started replacing removing the previous plots for reasons I couldn't understand.

[Elisa Prada]

I cannot see them. I am using Matlab R2015a and I have also tried in Matlab R2014b. Can it be a version problem??

[Elisa Prada]

I have tried in R2013a and it draws from 1 to 6 and also the last one (the 10th)

Ca you please tell me the version you are using?

[Adam]

I am using R2016a, but I also tested in R2015a
