You can use plot3(), but you'll have to configure your data according to what plot3() expects.
% some placeholder data
% g is a 2D array with individual series arranged as columns
x = -20:20;
sigma = linspace(3,5,10);
[yy xx] = meshgrid(sigma,x);
g = exp(-(xx./(1.414*yy)).^2);
plot3(xx,yy,g)
grid on
view(19,16)
Alternatively, you can just plot each series in a call to plot3() in a loop or something.
If you actually want an oblique projection like that, good luck. Oblique projections aren't supported. There is obliqueview() on the File Exchange, but parts of what it relies upon simply don't work anymore and would need to be rewritten.
