Matlab: Adding third dimenstion to 2D plot

2d, 3d, matlab, plot

Solution

If I understood correctly, you can simply give the plots different z-values. Example:

%# some random data
x = 1:300;
y = zeros(5,300);
for i=1:5
    y(i,:) = normpdf(x,100+i*20,10);
end

%# plot
hold on
clr = lines(5);
h = zeros(5,1);
for i=1:5
    h(i) = plot(x, y(i,:), 'Color',clr(i,:), 'LineWidth',2);
    set(h(i), 'ZData',ones(size(x))*i)
end
zlim([0 6]), box on, grid on
view(3)
hold off

Problem

I have the following code to generate me a 2D plot or 2 normal distributions: ``` res = zeros(2, 320); index = 1:320; % assign some data to the res array and then approximate: PD = fitdist(index','normal', 'frequency', res(1,:)') pdfNormal = normpdf(index',PD.mu,PD.sigma); plot(index', pdfNormal, 'Color', 'r', 'LineWidth', 2); hold on; PD = fitdist(index','normal', 'frequency', res(2,:)') pdfNormal = normpdf(index',PD.mu,PD.sigma); plot(index', pdfNormal, 'Color', 'b', 'LineWidth', 2); ``` This code generates me then the following picture: Now I am wondering how I could add a third dimension to this plot? Essentially, I would like to plot another 2 normal distributions, but this time in the Z-axis, ie., in the third dimension. Anyone an idea how I could do that easily? Thanks so much!
