  <p>I have made several attempts at plotting with the two y-axes corresponding to right two columns with the left most column being the x-axis. But so far I have only managed to get one axes for both. I have tried to mimic the solution here: <a href="http://matplotlib.org/examples/api/two_scales.html" rel="nofollow noreferrer">http://matplotlib.org/examples/api/two_scales.html</a> but I keep failing. I have also looked at other stackoverflow Q&amp;S but haven't found them very clear so far. Would be great if someone could help me solve this problem. Cheers.</p>
