The following figure shows the standard Seaborn/Matplotlib Boxplots in a 2 X 2 grid layout:
It is pretty much what I want except that I would like to put some more space between the first row of the of the plots and the second row. The distance between the X-axis labels of the first row plots and the title of the second row plots is almost non-existent. I have been playing with the parameters as explained in this thread:
Here is my relevant code:
import math
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages
from PyPDF2 import PdfFileMerger
import seaborn as sns
num_cols = 2
num_rows = int(math.ceil(tot_plots / float(num_cols)))
fig, axes = plt.subplots(nrows=num_rows, ncols=num_cols, figsize=(16, 16))
x_var = df_orig['hra']
for idx, ax in enumerate(axes.flat):
data_var = current_cols[idx]
y_var = df_orig[data_var]
title_str = ''
sns.boxplot(x=x_var, y=y_var, ax=ax,
order=order, palette=color, showfliers=False)
ax.set_title(data_var + title_str)
ax.xaxis.label.set_visible(False)
ax.yaxis.label.set_visible(False)
ax.xaxis.set_tick_params(labelsize=8)
ax.yaxis.set_tick_params(labelsize=8)
plt.setp(ax.xaxis.get_majorticklabels(), rotation=90)
fig.suptitle("Sampling BoxPlots", x=0.5, y=0.93, fontsize=14, fontweight="bold")
plt.tight_layout()
plt.subplots_adjust(top=0.8)
pdf_pages = PdfPages(file_name)
pdf_pages.savefig()
pdf_pages.close()
