Duplicate plots from statsmodels.api.graphics

[Adam Davis]

Using jupyter notebook, when I plot regresssions using statsmodels.api.graphics, the plots are always duplicated (see attached Capture1). When I plot a simple scatter plot using matplotlib from the same imports and data, it only plots once, as expected. Has anyone encountered this before? Can anyone suggest how to prevent the duplicates?

Please refer to code below.

Thanks,

Adam

import os
import statsmodels.api as sm
import pandas as pd
import numpy as np
from collections import defaultdict
from patsy import dmatrices

%matplotlib inline
import matplotlib
import matplotlib.pyplot as plt

df = pd.DataFrame({chr(i + 97): np.random.random(size=50) for i in range(3)})
y, X = dmatrices('a ~ b + c', data=df, return_type='dataframe')
mod = sm.OLS(y, X)
res = mod.fit()

sm.graphics.plot_partregress_grid(res) # duplicate plots

plt.scatter(df.a, df.b) #single scatter plot, as expected

That's the behavior of the notebook and nothing we can/will do about it.

You can assign the returned figure to something or `_`

Josef,

Assigning the return value is an acceptable workaround for me. Many thanks for pointing me at the relevant github issue for context.
