Hi Alok,
Please find attached the sample which displays 4 secondary axis excluding primary y axis. All the 5 are aligned in the same line and it looks more like a stacking line chart. Also it shows tooltips and support X zooming. Currently this sample does not provide support for Y zooming as expected but we will work on it and update you at the earliest.
