The antialiased keyword antialiased determines whether a particular matplotlib artist (for example, a line, a polygon, etc.) is drawn with anti-healing or not.
As an example, notice the difference in the two graphs below:
import matplotlib.pyplot as plt plt.subplot(1,2,1) plt.plot(range(10), antialiased=False) plt.title('Antialiasing Off') plt.subplot(1,2,2) plt.plot(range(10), antialiased=True) plt.title('Antialiasing On') plt.show()
An un-smoothed graph will be faster, so if you are drawing a large amount of data, it may be advisable to turn it off.
