Hello, I have thought of this might interesting to share. Register at www.sagenb.org or try on your local Sage-notebook and using the following code: # Simple example demonstrating how to interact with matplotlib directly. # Comment plt.clf() to get the plots overlay in each update. # Gokhan Sever & Harald Schilly (2010-01-24) from scipy import stats import numpy as np import matplotlib.pyplot as plt @interact def plot_norm(loc=(0,(0,10)), scale=(1,(1,10))): rv = stats.norm(loc, scale) x = np.linspace(-10,10,1000) plt.plot(x,rv.pdf(x)) plt.grid(True) plt.savefig('plt.png') plt.clf() A very easy to use example, also well-suited for learning and demonstration purposes.
