Question

I am plotting using Matplotlib in Python. I want create plot with grid, and here is an example from a plotting tutorial. In my plot range if the y axis is from 0 to 14 and if I use pylab.grid(True) then it makes a grid with the size of square of two, but I want the size to be 1. How can I force it?

Answer 1

Try using ax.grid(True, which='both') to position your grid lines on both major and minor ticks, as suggested here.

EDIT: Or just set your ticks manually, like this:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot([1,2,3,14],'ro-')

# set your ticks manually
ax.xaxis.set_ticks([1.,2.,3.,10.])
ax.grid(True)

plt.show()
