Chart taking List of generic data

[Bober02]

Hey everyone, I have a huge problem with passing data to charting component. I created a data IDataPoint<T>, with properties:

T X  -> generic

decimal Y 

 and then I pass a List<IDataPoint<T>> to charting component and set XAxis to point to property X.

 Now, Charting component cannot work out on its own, when I pass him List of IDataPoint<decimal> that X is a decimal number, so I get 1 instead of e.g. 1.6584. Can I manually set the Axis property to tell explicitly that X is a decimal number?
