Warnings when used with pandas 2.1.0 #34

Closed schloerke closed 1 year ago

From https://github.com/has2k1/plotnine/issues/713

With pandas 2.1.0, using plotnine results in a number of warnings from is_categorical_dtype.

For example:

from plotnine import ggplot, geom_point, aes, stat_smooth, facet_wrap
from plotnine.data import mtcars

ggplot(mtcars, aes("wt", "mpg", color="factor(gear)")) + geom_point()
