Display x-axis while drawing dynamic line series

I am refering the example @ http://ift.tt/1gCnhRn

to draw a dynamic line series.



It works fine apart from displaying an x-axis properly



I was able to add an x-axis but, its x-value is getting plotted wrongly in that case.



It is plotting values properly according to y-axis but taking some random value for X



Please help!
