[Support #TWK-728245]: Re: Python support post AMS workshop

Greetings!

(1) In order to save your plot as an image, all you need to add is a call to 
`plt.savefig`:

    plt.savefig('myfigure.png')

The format of the image is dictated by the file extension.

(2) Right now there are quite a few MetPy calculations (especially ones like 
wet bulb that rely on the calculation of moist adiabats) that do not 
intrinsically work with grids of data--thus the only solution is manual looping 
over the grids. As you noted, this is really slow. We have definite plans to 
address these limitations in the future, but at the moment unfortunately manual 
looping over grid points is the only solution.

Cheers,

Ryan
