Try this:

x = (1:10)';
y = [10 10 9 8 8 7 6 6 5 5;
      9  8 7 6 6 5 4 4 4 4;
     12 10 9 9 9 9 6 6 5 5]';

figure
hold all
for k = 1:size(y,2)
    plot3(x, y(:,k), ones(size(x))*k)
end
hold off
grid on
xlabel('X')
ylabel('Y')
zlabel('Alt Number')
zlim([0  size(y,2)])
set(gca, 'ZTick',(0:size(y,2)), 'ZTickLabel',(0:size(y,2)))
view(-40,30)

Make appropriate changes to get the result you want.
