Animation of waves

Share icon

So I have plotted a number of waves on a movie (say 100 frames) using  AppendToGraph and it works fine. Just as an enhancement to the visualization, I would like the waves to appear as I vary the frames. I tried using  DelayUpdate but in vain.

The image shows current plot. I want the lines to appear as I move the frames.

Any help is greatly appreciated. Thanks!!
Are you saying you want 1 wave to appear in each frame? In a for loop append 1 wave, then addframetomovie. loop until all waves are plotted.

If you have a set of waves appended to a graph and just want to visualize them sequentially, you might try the Scroll Traces package ...

You can make a movie from this by writing a plug-in function to store each step in the graph to a movie frame.

If you are doing this from a function, you need to call DoUpdate after each change to the graph or a wave on the graph to force Igor to redraw the graph.

Thank you very much for the suggestions, I just ran into a small problem in the scroll traces, I am not able to run it since an error is being generated as shown in the image!
I know its a simple one but cannot figure out how to get rid of the error and start using the package!


Thanks again!

That error implies that the constant is being declared twice. Do you have any other procedure files that includes the scroll traces code?

The screenshot in your first post looks as though it was created using my Localizer package, and it appears as if you're using particle tracking. I assume that you want to animate the particle tracking.

If that is the case, I've tried to include support for this natively - simply show the tracks using the GUI controls, and make sure that "tracks are constructed with movie playback" is checked. Then go to Macros -> Localizer -> Save topmost movie as, and choose "presentation movie".
