单击highcharts stack bar时如何打开页面？

I am creating a stacked bar chart with help of highcharts.

When I click on any part of bar I want to open a new page that displays containing data. How can I achieve this?

As shown in this image the graph is not stacked as it should be. It is displayed as different three vertical bars. How can I fix this?
