[Solved]-How can I prepare a Group Stacked Bar Chart in Highcharts using multiple and different types of data?-Highcharts

So, if you can create JSON like this:

A = { 
    Ax: [Ax1, Ax2], 
    Ay: [Ay1, Ay2] 
}

that will mean you are on a good way.

Now the question remains: how should be displayed? For example: http://jsfiddle.net/gqMLk/ (but where should be third bar of A? ).
