Wrong code and spelling

[mzl9039]

hi, thanks for your work on this awesome book! I just start reading and it helps me much on understanding matplotlib!

by the way, i found a mistake on Scales & projections

It is the code below:

   >>> fig = plt.figure(figsize=(6,6))
   >>> ax = plt.subplot(1, 1, 1,
                        aspect=1, xlim=[0,100], ylim=[0,100])
   >>> P0, P1, P2, P3 = (0.1, 0.1), (1,1), (10,10), (100,100)
   >>> transform = ax.transData.transform
   >>> print( (transform(P1)-transform(P0))[0] )
   4.185
   >>> print( (transform(P2)-transform(P1))[0] )
   41.85
   >>> print( (transform(P1)-transform(P0))[0] )
   418.5

the last one should be:

print( (transform(P3)-transform(P2))[0] )

same issues occurred both on checking "linear scale" and "log scale"

You're right, thanks. Can you make a PR?
