Hello Dai,

First let me direct you to one of our online demos: Point, Gantt, Bubble Chart (select "Bubble" from the drop down list). This will give you a notion of how the RadChart in Asp.Net Ajax draws a bubble chart. In short - the YValue is the center of the ellipse and the YValue2 is the ellipse's height.

If you comment out the plot area from the code that you have provided - you will start to see a more meaningful output.

However, I think that this might not be what you want exactly and this is why I have attached a simple app to get you started with one of the ways to create a bubble chart. I have also attached a snapshot of the output that I get when I run this code.

Hope this is of help. 

Kind regards,
