Debug a highcharts graph

I have two drill down column graphs which I want to create. The data is already is the database. The challenge I'm having is that I cannot get dynamic x-axis values when I drill down. What I mean by this is that if there is a value added or removed from the database which would have gone into the second or third level of the graph, then it should appear/disappear from the graph. I don't think it would be hard for an experienced programmer to find the solution. I will also share with you a preview before you receive the bid so you can make sure you know how to resolve the issue. If you are awarded the project, you will be expected to work with me via skype on my screen (screen sharing), so I can also learn what I was doing wrong.
