Bugs in non quadratic pairplots

[markus783]

From version 0.9.0 to version 0.11.0 the "diagonal" on non quadratic pairplots is empty.

Sample Code:

import seaborn as sns
import pandas as pd 
from matplotlib import pyplot as plt

test_df = pd.DataFrame({"a": [1,2,3,4], "b": [3,4,5,6], "c": [5,3,6,1]})
sns.pairplot(test_df, x_vars=["a"], y_vars=["b", "c"])
plt.show()

The top graph is empty although a scatter plot should be shown in place as the two columns have matching indices.

Yes, this is also a problem we had at our company. We solved it by just not using non quadratic pairplots.
