To answer the question of using data not normally on the MATLAB path, I offer the following modification.
 
if ~exist('contest_data.mat','file')
    warning ('This was an entry to the MATLAB programming contest (http://www.mathworks.com/contest/datavis/home.html). Please load the contest data and unzip it to place contest_data.mat on your MATLAB path.')
    web('http://www.mathworks.com/matlabcentral/fileexchange/23509?controller=file_infos&download=true')
end

I am trying to use the zoombox, but the box does not show any data.

This is my code-- The way I am trying to call the zoombox
x=(0:0.001:25);

y = 1.5*cos(x) + 6*exp(-.1*x) + exp(.07*x).*sin(3*x);
hChildAxes = subplot(2,1,1); %child
plot([2 3 4],0)
hParentAxes = subplot(2,1,2); %parent
p=plot(hParentAxes,x,y);
ym = mean(y);
hold on
plot(hParentAxes,[min(x) max(x)],[ym ym],'Color','red')
hold off

ylab = get(hParentAxes,'YTick')
set(hParentAxes,'YTick',sort([ylab ym]))
zoomBox(hParentAxes, hChildAxes,0)

Please help!!

If you have a code that uses this and works could you share it with me please?

Thx a lot Hull. This video is very helpful. And I like your tone. Very relaxed and fun.
