Six features, in one intuitive display!
1) The 3D snake shows the complex behavior of f(x) over x.
2) The floor projection shows the real behavior.
3) The right projection shows the imaginary behavior.
4) The backprojection shows the complex plane.
5) The magnitude of f(x) is visualized in the thickness of the snake.
6) Finally, the rainbow colors of the added soap skin reflect the phase of f(x).
The function plots any complex function you like:
f(x) = exp(ix);
f(x) = x.^x;
f(x) = log(x);
f(x) = sin(i*x);
A couple of examples are added in the demo file.
NB: It is also possible to show the complex spectrum of (simple) time signals, however, sometimes the settings in the function must be chosen carefully!
