As of now it is not possible to position axisY at the center of the chart. However, you can workaround this by positioning axisY of another chart (without any dataPoint) in the background of current chart. Please check this jsfiddle.

I tried the jsfiddle, it works. Thanks very much for your prompt response. But how can it support zooming in this case? The axisY chart is not zoomed with the main chart.
