Hi


I have a web app that calculates percentage scores for 4 subject areas.
eg 20, 40, 10, 30

What VB.net code would I use to show these scores in the ASP.net chart,
whose markup is shown below. Thanks


    <asp:Chart ID="Chart5" runat="server" Height="336px" Width="348px">
        <Titles>
            <asp:Title Text="">
            </asp:Title>
        </Titles>
        <series>
            <asp:Series BorderWidth="5" ChartArea="MainChartArea" ChartType="Pie"
                Color="#000024" Name="MyCategories" YValuesPerPoint="6">
            </asp:Series>
        </series>
        <chartareas>
            <asp:ChartArea Name="MainChartArea">
            </asp:ChartArea>
        </chartareas>
    </asp:Chart>
