Hi Krishna,

I'm not sure about using FixedLocator if you want to zoom ... 
What about the following approach:

from matplotlib import pyplot as plt
ax = plt.subplot(111, autoscale_on=False, xlim=(10, 1000), ylim=(10,  1000))
ax.set_xscale('log')
ax.set_yscale('log')
ax.grid(which='major', linestyle='-', color='blue')
ax.grid(which='minor', linestyle='--', color='red')
plt.show()

Kind regards,
Matthias
