This is a minimal utility for creating a "beauty" printing of seaborn pairplot function. It remove self comparisons and split lines into an specified number of items

PlotHelper

Import library

The plothelper.py file should be in the same folder

import numpy as np
import pandas as pd
from plothelper import PlotHelper as PH
%matplotlib inline

Load dataset with pandas

# load dataset
dfHouses = pd.read_csv('kc_house_data.csv')

Using PH.pairplot

This is the same function that seaborn.pairplot() but it has two new parameters:

• max_per_row: maximum charts in the same row
• reg_line_color: if the type of the chart is kind='reg', this property paints the regression line in the color choosen

PH().pairplot(data=dfHouses,
              x_vars=dfHouses.columns.tolist(),
              y_vars=['price'],
              max_per_row=5,
              kind='reg',
              reg_line_color='red')
