Hi,

I'm trying to animate a line object, which should traslate sinusoidally in the vertical axis and rotate sinusoidally with respect to a point of the same line both at the same time.

Thanks in advance for your attention.

Edit: Maybe I've been too brief. I'm trying to plot it in a GUI's axes. The thing is that with rotate and traslate commands I can't make it describe the movement I want, because the rotation center is moving as well (it belongs to the line). It should be inside a while (so that it moves until user pushes stop button), so I guess that inside rotate and translate should be a function, as well as for the origin or rotation center. I hope this clarifies the question.

See the animatedline() function. From the help:

Description
h = animatedline creates an animated line that has no data and adds it to the current axes. Add points to the line in a loop to create a line animation. For more information, see Using animatedline Objects.

I've also attached a demo of making a movie from a plot/graph that you create.
