How to plot a stack of curves in Matlab, as attached figure?

Hope it is possible with matlab to plot a stack of curves, better with hidden lines, like this attached figure:

Answer 1

The easiest way is probably just to add a small offset to the ydata:

nx = 100;
ny = 50;

ysig = rand(nx,1);

x = 1:(nx+ny);

y = nan(nx+ny,ny);
for ii = 1:50
    y(ii:(ii+nx-1),ii) = ysig;
end

dy = 1;
ystaggered = bsxfun(@plus, y, (0:ny-1)*dy)

figure('color','k');
axes('color', 'k', 'xcolor','w');
line(x, ystaggered);

You could also try creating a lot of overlapping axes (as with plotses).

figure('color', 'k');
[hl,ha] = plotses(x,y);
set(ha, 'xcolor', 'w', 'ycolor', 'k');
set(ha(2:end), 'visible', 'off');

That appears to be a waterfall plot. Which is actually a mesh plot with lines drawn only in one direction.

waterfall will not do that well. 1) waterfall is a 3D looking with view angles; 2) if plot black, the baseline will be plot, very ugly and messy; 2) with 'column' or 'raw' line only, there are missing sections.

Anyways, the water fall isn't a good way. Above is plot with IDL.

My choice would be to use a ribbon plot. Then play with the plot parameters until it looks the way you want it to.
