在Matlab中交叉的茎图

Question

I would like to reproduce in Matlab a plot that looks like this:

The stem3 plot command sounds nice but only for the vertical stems. Not the second series with the horizontal ones.

Everything would be easy if I could plot using the usual commands and rotate the result.

Answer 1

How a about this? Manually plot each line in 3D stemming from the x axis:

x = 0:.01:2*pi*3;
z = sin(x);
y = -sin(x);

hold on
for n = 1:numel(x);
    plot3([x(n) x(n)], [0 y(n)], [0 0], 'r');
    plot3([x(n) x(n)], [0 0], [0 z(n)], 'b');
end

As noted by @TheMinion, it's easier to use fill3 :

x = 0:.01:2*pi*3;
z = sin(x);
y = -sin(x);

fill3(x,y,zeros(size(x)),'r')
hold on
fill3(x,zeros(size(x)),z,'b')
