Hi Alex,
here is exported notebook and sample data.
Notebook is quite havy (19MB) where can I upload it?
Here is some code sample:
%pyspark
import matplotlib
import os
from pylab import figure, show, rand
from matplotlib.patches import Ellipse
import matplotlib.pyplot as plt
# helper function to display in Zeppelin
matplotlib.use('Agg')
os.system("export DISPLAY=:0")
plt.switch_backend('Agg')
import StringIO
def show(p):
img = StringIO.StringIO()
p.savefig(img, format='svg')
img.seek(0)
print "%html <div style='width:600px'>" + img.buf + "</div>"
%pyspark
data_1 = data.ix[data['y']==1]
data_0 = data.ix[data['y']==0]
x_1 = data_1['balance'].values
y_1 = data_1['age'].values
x_0 = data_0['balance'].values
y_0 = data_0['age'].values
colors = ['red','green']
plt.figure(figsize=(10, 6))
plt.xlabel('Balance')
plt.ylabel('Age')
plt.title('')
plt.scatter(x_0, y_0, alpha=0.5, color='blue')
plt.scatter(x_1, y_1, alpha=0.5, color='red')#matplotlib.
colors.ListedColormap(colors)
plt.title('Destributions of balance by age and target value')
show(plt)
plt.close()
Regards,
Andrey
