Does this get you where you want to be?
import pylab
datax = pylab.arange(50)
data1 = pylab.sin(datax)*1.5
data2 = datax**2
pylab.close('all')
fig = pylab.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twinx()
ax1.plot(datax, data1, 'x')
ax2.plot(datax, data2, '--')
for ax in [ax1, ax2]:
ax.xaxis.grid(True, which='both') # `which` can be 'minor', 'major', or
'both'
ax.yaxis.grid(True, which='both')
fig.show()
