<Series>
                <asp:Series ChartType="Column"   Name="Saturday"  BorderWidth="3" Color="#D8D8D8" LabelForeColor="Blue"></asp:Series>
                <asp:Series ChartType="Column"  Name="Sunday"   BorderWidth="3" Color="#A9E2F3" LabelForeColor="Blue" ></asp:Series>
                <asp:Series ChartType="Line"  Name="MondayToThursday" IsValueShownAsLabel="true"  BorderWidth="3" Color="Orange" LabelForeColor="Blue"></asp:Series>
                <asp:Series ChartType="Column"  Name="Friday"   BorderWidth="3" Color="#BCF5A9" LabelForeColor="Blue"  > </asp:Series>              
            </Series>

1) How can i hide specific data series "values label" on code level.
2) There are small arrows on the chart labels "black arrows" how can i remove them.
3) In chart some of values are "0" and my y-axis also starts from "0" can i give padding to chart.
