1. twinx and grid (garyr)

Hi Gary

To get more control on which grid shows / doesn't, you can do:

ax1.grid('on')
ax2.grid('off')

instead of:

plt.grid()

The script below labels both the left and right x-axes and shows a grid. Is
there a way to force the horizontal grid lines to line up with the tic marks on
the left axis (ax1)?

import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax1 = fig.add_subplot(111)
t = np.arange(0.01, 10.0, 0.01)
s1 = np.exp(t)
ax1.plot(t, s1, 'b-')
ax2 = ax1.twinx()
s2 = np.sin(2*np.pi*t)
ax2.plot(t, s2, 'r')
plt.grid()
plt.show()
