title: Google Spreadsheets: How to add multiple y axis for a Timeline chart
body: <p>I have a table with multiple columns. First column is date and the rest are unit price of A, B etc... A and B are on different scales (Say 10 and 1000). If I plot the Timeline chart, I do not have a way to see both A and B on different scales. 
  How can I configure multiple y axes with different ranges? Any apis out there?<a href="https://i.stack.imgur.com/JL3A4.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/JL3A4.jpg" alt="timeline chart"></a></p>
