Line Graph with multiple Y-Axis

Hello Guys, i am currently working on a dual access graph which has two y-axis(on a left hand side and on a right hand side), now i would like to ask how to plot value into the graph my values are coming from the datapoints, what is currently happening with this graph is that i can only display the first value in the list and the other value are not showing. Please see my code below. 

Hi Mthunzi,

I see you used comments ("//") in your JSON code, but that won't work, there's no such thing as comments in JSON (see e.g. here).

As for having to y-axes, Highcharts has examples for this situation, which you can compare to your code.
