Bar Chart Ajax Toolkit

GoodMorning,

i'm new on developing with ASP.NET and Ajax technology.

I have to create a graph, and i have choose the bar chart who i have found in ajax control toolkit. I wanto to say how i can populate dinamically the graph from code.

Here an example of my graph

<asp:BarChart ID="BarChart1" runat="server" ChartType="Column"  ChartHeight="500" ChartWidth="900" CategoriesAxis="1,2,3,4,5"><Series><asp:BarChartSeries Name="Incassi" Data="" /><asp:BarChartSeries Name="Incassi" Data="" /></Series></asp:BarChart>

I want to insert programmatically the "Data" value.

Thankyou
