plt.savefig produces blank figure in Python

I want to save a plot as a png. The following code produces a blank figure:

import numpy as np
import matplotlib.pyplot as plt
x = np.linspace (0 , 10, 1000)
y = x**2
plt.plot(x, y)
plt.savefig('line_plot.png', dpi=100)

I am using Python 3.6 together with Anaconda and Spyder 3.2.0. How can I get a png containing the desired plot?

Try using the Figure object directly.

fig=plt.figure()
plt.plot(x,y)
fig.savefig('line_plot.png', dpi=100)

If you are interested in a PNG use '.png' instead of '.jpg'. Depending on the GUI toolkit you may need to add fig.show() before the last line.
