2D contour with multiple data sets

Plot 2D contour with multiple data sets using some default settings.

import coplot.plot_contours as plc
import matplotlib.pyplot as plt
import numpy as np


test1 = np.random.randn(50000, 2)
a1, b1 = test1[:,0], test1[:,1]
test2 = test1 + 1
a2, b2 = test2[:,0], test2[:,1]

# If you want to use some default settings, you can use it like this:
fig = plc.Plot_2d([[a1,b1],[a2,b2]]).plot(labels=[r'$a$', r'$b$'],
                                          legend=True,ticks_size=10)
# pl.savefig('test_2d_2.pdf', fig)
plt.show()
