ReliabilityDiagram.plot() makes duplicate copy of figure

[jmsdao]

Code to recreate (I ran it in Google Colab):

!pip install netcal

import numpy as np
from netcal.presentation import ReliabilityDiagram

conf = np.random.rand(1000)
ground = np.random.randint(0, 2, 1000)

diag = ReliabilityDiagram(20)
diag.plot(conf, ground)

Results of !pip show netcal:

Also wanted to say, this is a great library!

Sorry, I am silly. Adding a semicolon on the line with .plot() fixes this.
