Hi Eyal,
You have opened this thread with a product RadChart, but to me it seems you may be referring to the RadChartView control. Please clarify this so that we will be able to help you. Also I was not able to fully understand what is the actual problem. Is it possible that you send us some snapshots that depict what you have so far and what you are trying to achieve?
All the best,
