As an example, the following code, from CH01_SEC04_1_Linear.ipynb,

plt.plot(a, x*a, Color='k', LineWidth=2, label='True line') # True relationship
plt.plot(a, b, 'x', Color='r', MarkerSize = 10, label='Noisy data') # Noisy measurements

should now be:

plt.plot(a, x*a, Color='k', linewidth=2, label='True line') # True relationship
plt.plot(a, b, 'x', Color='r', markersize = 10, label='Noisy data') # Noisy measurements
