Using Scrollbars in Matlab when trying to view a large number of plots

I am trying to use a scrollbar to slide through a large number of plots. I have combined the following:

https://www.mathworks.com/matlabcentral/answers/97964-how-can-i-use-scrollbars-in-matlab-figure-windows-when-viewing-large-guis

with other code in order to do so, but regardless of what I do I cannot seem to change the size of 'panel2'. i.e., in this example I am trying to plot 20 graphs, but it will only show 10 before they end up outside of the where the slider can move to, and none of the 'Position' sets seem to help with this at all.

figPos = [200 200 800 1000];
figure('Color', 'w', 'Position', figPos)
panel1 = uipanel('Parent',2);
panel2 = uipanel('Parent',panel1);
set(panel1, 'Position',[0 0 0.95 1]);
set(panel2,'Position',[0 -1 1 20]);

s = uicontrol('Style','Slider','Parent',2,...
  'Units','normalized','Position',[0.95 0 0.05 1],...
  'Value',1,'Callback',{@slider_callback1,panel2});

leftPadding = .0625; % the space at the left of the figure
horizPadding = .1; % the space between axes (horizontally)
bottomPadding = .05; % the space at the bottom of the figure
vertPadding = .1; % the space between axes (vertically)

nHorizAxes = 2;
nVertAxes = 20;

width = .35;
height = .1;

x = linspace(0, 2*pi);
y = sin(x);

for iRow = 1:nVertAxes
    for iCol = 1:nHorizAxes
        % calculate the position
        left = leftPadding+(iCol-1)*(width+horizPadding);
        bottom = bottomPadding+(iRow-1)*(height+vertPadding);
        position = [left bottom width height];

        %myAxes(iRow, iCol) = axes('Position', position);
        ax = axes(panel2,'Position', position);
        plot(x, y, 'b', 'Parent', ax)
        xlabel('Percentage Target Load (%)')
        ylabel('Percentage Target Strain (%)')
        title(sprintf('axes(%d, %d)', iRow, iCol))
    end
end

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

I was forced to place the plots within axes(). As apparently you cannot plot directly into a uipanel. Not sure if that is part of the issue? And if so what the workaround might be?

Also there are other techniques if you switch to uifigure()

Thanks, I ended up going with this approach and it worked well for me!
