repeat y axis scale along grid line of graph ( matplotlib)

Question

Hello,

I am new to matplotlib and I am trying to figure out if I can repeat the y axis scale values along the grid lines of the line graph.

The graph has 2 axis, x-axis has hourly values and y-axis has temperature values.

I need to show the graph for 48 hours, so it results in a long horizontal graph. when user scrolls through the graph horizontally he has x-axis scale available for reference but y axis scale is way towards left and is not visible.

I need a way to repeat the y-axis scale(temperature values) along all the graph. Is there any way to achieve this?

Is there any better solution to this problem, apart from repeating the values?

You might take a look at the colorbar from this example:

import matplotlib.pyplot as plt
import numpy as np
from matplotlib.collections import EllipseCollection

x = np.arange(10)
y = np.arange(15)
X, Y = np.meshgrid(x, y)

XY = np.hstack((X.ravel()[:,np.newaxis], Y.ravel()[:,np.newaxis]))

ww = X/10.0
hh = Y/15.0
aa = X*9


ax = plt.subplot(1,1,1)

ec = EllipseCollection(
                        ww,
                        hh,
                        aa,
                        units='x',
                        offsets=XY,
                        transOffset=ax.transData)
ec.set_array((X+Y).ravel())
ax.add_collection(ec)
ax.autoscale_view()
ax.set_xlabel('X')
ax.set_ylabel('y')
cbar = plt.colorbar(ec)
cbar.set_label('X+Y')
plt.show()

A quick experiment shows me that you can pan/zoom the main window and the colorbar will stay constant.
