Hello everybody.

I would like to animate simultaneously a 2D contour and a XY line. All the data are transient and the XY line corresponds to some average data calculated on the contour versus the time.

Thus I would like to animate the 2D contour and see a moving line on my XY line corresponding to the time step as illustrated on this video, at 1:40.

Does someone have any clue to do this kind of animation ? I tried manually to draw a line and moving it with a loop but without succes.

Thank you in advance for your help.
