====== General instructions ======

Read following important documentation about:
  * pandas [[http://pandas.pydata.org/pandas-docs/stable/dsintro.html#dataframe|dataframes]]
  * [[http://matplotlib.org/api/pyplot_summary.html|matplotlib.pyplot]]

Save your scripts in a folder inside the data folder, calling the script folder 'my_scripts' or whaterver. If  'my-scripts' is set as your [[python:generic_features#get_the_current_working_directory_address|current working directory]], then the data files are available under this address '../[data file]', for instantce: '../geyser1.TAB'

===== Histogram (p.5) =====

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

<code python>
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() 
</code>


\\

===== Boxplot (p. 6) =====

<code python>
import matplotlib.pyplot as plt
import pandas as pd
gysr1_boxplot = pd.read_csv('...\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')
plt.show()
</code>


\\

===== ScatterPlot (p. 7) =====

AB: Put face- and edgecolor to change both of them. You can also have two different colors for the in- and outside of each dot.

<code python>
import matplotlib.pyplot as plt
import pandas as pd
geysr1_scatterplot = pd.read_csv('...\geyser1.TAB', '\t')
geysr1_data_Xax = geysr1_scatterplot['Duration']
geysr1_data_Yax = geysr1_scatterplot['Interval']
plt.scatter(geysr1_data_Xax, geysr1_data_Yax, facecolor='y', edgecolor='y')
ax = plt.gca()
ax.set_xlabel('Eruption duration time (minutes)')
ax.set_ylabel('Interuption time (minutes)')
ax.set_title('Scatter Plot of INTERVAL vs DURATION')
plt.show()
</code>
