Eventhough I get a proper diagram (yeay!), I also get this warning each time I run ggplot:
FutureWarning: Attribute 'is_copy' is deprecated and will be removed in a future version.return object.__setattr__(self, name, value)
I use Python 3.6 and:
from plotnine import * #Vers. 0.3.0
import pandas as pd #Vers. 0.23.1
from pandas import DataFrame
The ggplot code is:
g = ggplot(df, aes(x='date', y='meanDN')) + geom_point()
print(g)
Should I be concerened?
The warning comes from a call to the pandas library. plotnine still uses a functionality of pandas that has been deprecated and will be removed in a future version.
Plotnine is actively developed, and this bug has been fixed already.
There was no new release after plotnine 0.3.0 yet, so you will have to install the development version from GitHub or wait for a new release to make the warning go away.
