SunPy visualization question

[Ellis Avallone]

Hello,

I'm currently trying to animate MapCube objects  in order to check for coalignment using the MapCubeAnimator class, and I was wondering if there was any way to save the animation as a .mp4?

I also noticed that the documentation wasn't very thorough. Is this class still in the works, and if so, would be easier to just use matplotlib.animate?

Thanks in advance!

Hi Ellis,

The animator class is pretty stable, but the documentation could be better!

You can use the MapCubeAnimator to get a matplotlib.animation.FuncAnimator object with the `get_animation` method: http://docs.sunpy.org/en/latest/generated/api/sunpy.visualization.imageanimator.BaseFuncAnimator.html#sunpy.visualization.imageanimator.BaseFuncAnimator.get_animation

If you have a MapCube you can also use the `MapCube.plot()` method which will return (an almost identical) mpl animation object.

Hope that helps,

Stuart

Thank you so much!! That helped a ton.

I noticed while playing with MapCubeAnimator a bit more that, while it does accept map.plot() kwargs it does not implement them. I've been trying to change the min and max values of the colormaps in my animation and have been unable to do so using MapCubeAnimator. Do you know why that is?

Ellis,

If you are trying to change vmin and vmax for every map in the mapcube, then you have to change vmin and vmax in each map.  This code:

https://github.com/wafels/eitwave/blob/master/mapcube_tools.py#L55

shows one way of doing this.

Hope this helps,

Jack
