This works well. Thank you.

Now, at the risk of overloading this topic, how can I make the colors consistent across multiple maps of different cities. For example, here are Manchester and London compared:

The colormap is autoscaled to the data in each map, so the colors are not comparable between the two. Can I fix this, so that the colorbar is consistent across multiple maps?
