i am using DEVX Webchart control..

Bind x-Axis values:

<dxchartsui:WebChartControl ID="ChartOPCGraph" 
                            runat="server" 
                            Height="400px" Width="700px"
                            ClientInstanceName="ChartOPCGraph" 
                            DiagramTypeName="XYDiagram">
    <Diagram>
        <axisy>
            <gridlines visible="False"></gridlines>
        </axisy>
    </Diagram>
    <Titles>
        <cc1:ChartTitle Dock="Bottom" 
                        Font="Tahoma, 8pt" Text="Days" 
                        TextColor="Gray" 
                        Alignment="Center">
        </cc1:ChartTitle>
        <cc1:ChartTitle Dock="Left" 
                        Font="Tahoma, 8pt" Text="% Payment made" 
                        TextColor="Gray"
                        Alignment="Center">
        </cc1:ChartTitle>
    </Titles>
</dxchartsui:WebChartControl>

values are being populated from database.
On x-axis only two number comes from database so i need to bind only these two values and rest of them must not be visible.

For example i get 9 number from database and it binds 8.6,8.7,8.8,8.9,9,9.2,......

i am binding chart using:

ChartOPCGraph.DataSource = dsClaim.Tables[0];
ChartOPCGraph.SeriesDataMember = dsClaim.Tables[0].Columns["per"].ToString();
ChartOPCGraph.SeriesTemplate.ArgumentScaleType = ScaleType.Numerical;
ChartOPCGraph.SeriesTemplate.ArgumentDataMember = dsClaim.Tables[0].Columns["paymentDays"].ToString();
ChartOPCGraph.SeriesTemplate.ValueDataMembers.AddRange(new string[] { dsClaim.Tables[0].Columns["per"].ToString() });
string paletteName = "MyPalette";
PaletteEntry entry1 = new PaletteEntry(Color.Green, Color.LightGreen);
Palette palette = new Palette(paletteName, new PaletteEntry[] { entry1 });
ChartOPCGraph.PaletteRepository.Add(paletteName, palette);
ChartOPCGraph.PaletteName = paletteName;
SideBySideBarSeriesView objWidth = new SideBySideBarSeriesView();
objWidth.BarWidth = 0.3;
ChartOPCGraph.SeriesTemplate.View = objWidth;
ChartOPCGraph.DataBind();

Need a quick reply..
