I looked through your code and can say that everything is good with it. How the scales look depends on the range of values in the series. If you have in your first series a range of 0 to 1000 and for the second - 0 to 100, you will see that the two Y Axes have different scales. I hope you will find this helpful.
In case, I have not understood your question, can you please explain with more details what you are trying to achieve and send us a sample runnable project with what you tried up to now? I will really appreciate if you send a screenshot of what you are getting and another picture or a drawing of what you are trying to get.
All the best,
