Description

Originally reported by: Stuart Mumford (Bitbucket: smumford, GitHub: smumford)

I would like to be able to animate changing the location of a SlicePlot, i.e. sweeping through a domain.

Something like this

slc = yt.SlicePlot(ds_h5, 'z', 'VortXmag', origin='left-domain', center=(1e8,1e8,10*12.5e5))
slc.set_window_size(8)

fig = slc.plots['VortXmag'].figure
def animate(i):
    slc.set_center((1e8,1e8,i*12.5e5))

animation.FuncAnimation(fig, animate, frames=range(0,127,2), interval=50, blit=True)

Contributor guide

Research direction
Investigate the SlicePlot class in yt/visualization/plot window.py to understand how the center is set. Then modify the `set center` method or implement a method to update the plot center dynamically.
