Density plot from multiple plots
Posted: Sep 16, 2013 6:08 PM

Hi,

I use

plot(x_axis, OriginalData);
hold all;

for trial=1:1000
f = getData(...);
plot(x_acis, f);
end

The different f-functions are all concentrated around "OriginalData"
(more or less randomly with some variance).

I want to plot now the "envelope" as well as a "density" plot, i.e.
where most of the instances lie.

I played around with creating a matrix and manually using a counter but
that does not only take hours but it's also unreliable (needs to
precicly know the dimensions) and the interpolation between the points
is missing.

Thanks
Peter
