FutureWarning in Pandas 0.24.0
See original GitHub issuePandas 0.24.0 throws a FutureWarning when used with Altair 2.3.0 here, which prevents the chart being rendered correctly. The message:
[my_virtualenv]/lib/python3.6/site-packages/altair/utils/core.py:294: FutureWarning: A future version of pandas will default to `skipna=True`. To silence this warning, pass `skipna=True|False` explicitly.
I notice that Altair’s requirements.txt doesn’t specify version. Would it be worth doing so?

I pushed a fix in #1315
Fix is to explicitly pass
skipna=Falsein this line: https://github.com/altair-viz/altair/blob/c4495f965db621e8bd0c2b3dd0390ef30ad33456/altair/utils/core.py#L72We’ll have to do it carefully, though, because prior to pandas 0.20.0,
infer_dtypetakes no keyword arguments.
