A complete example

Let's now group together all that we've seen so far and create a complete example as follows:

In [1]: import matplotlib.pyplot as plt
In [2]: import numpy as np
In [3]: x = np.arange(1, 5)
In [4]: plt.plot(x, x*1.5, label='Normal')
Out[4]: [<matplotlib.lines.Line2D object at 0x2ab5f50>]
In [5]: plt.plot(x, x*3.0, label='Fast')
Out[5]: [<matplotlib.lines.Line2D object at 0x2ac5210>]
In [6]: plt.plot(x, x/3.0, label='Slow')
Out[6]: [<matplotlib.lines.Line2D object at 0x2ac5650>]
In [7]: plt.grid(True)
In [8]: plt.title('Sample Growth of a Measure')
Out[8]: <matplotlib.text.Text object at 0x2aa8890>
In [9]: plt.xlabel('Samples')
Out[9]: <matplotlib.text.Text object at 0x2aa6150>
In [10]: plt.ylabel('Values Measured')
Out[10]: <matplotlib.text.Text object at 0x2aa6d10>
In [11]: plt.legend(loc='upper left')
Out[11]: <matplotlib.legend.Legend object at 0x2ac5c50>
In [12]: plt.show()

A very nice looking plot can be obtained with just...
