FB: this script works fine ! Do not delete it !

import pandas as pd
import matplotlib.pyplot as plt
gys1 = pd.DataFrame(pd.read_csv('../geyser1.TAB', '\t'))
g_int = gys1['Interval']
ax = plt.gca()
ax.hist(g_int, bins=20, color='r')
ax.set_xlabel('Intereruption time')
ax.set_ylabel('Frequency')
ax.set_title('Histogram')
plt.show()

Boxplot (p. 6)

import matplotlib.pyplot as plt
import pandas as pd
gysr1_boxplot = pd.read_csv('D:\Python\Libri\A Casebook for a First Course in Statistics and Data Analysis Datasets\Data\Tab\geyser1.TAB', '\t')
data_gysr1 = gysr1_boxplot['Interval']
plt.boxplot(data_gysr1)
ax = plt.gca()
ax.set_xlabel('222 cases')
ax.set_ylabel('Interruption time ( minutes')
ax.set_title('Box and Whisker Plot')
