Yes, I was actually wondering how I should properly test this (and how the plot tests are done). I have added very basic tests. |

There was a problem hiding this comment.
Thanks. Needs a release note in 1.0.0.rst.

When Series or DataFrames was empty (no cells) after removing columns without a suitable type (.select_dtypes), pandas was throwing a "no numeric data to plot" exception. This can happen: 1) either because there is no column with a suitable type; 2) or if there is no row. Raising an exception in the first case makes sense but we should probably avoid throwing an exception in the second case.
