Baselines and aspect ratios

[amueller]

Loving this so far and using it in my lecture!
I have not gone through all of it yet, but I think you're not talking about issues of baselines and issues of aspect ratio.
I think they might be interesting to point out.

Here's two blogposts that seemed interesting on the topic:

In particular your baseline or aspect ratio can change dramatically if you add new data to a plot.
