How can I hide X value label, if there is no Y value?
For example I want to hide X axis values 16 and 18

Hi @Hema Ramachandran ,
I think you can use an if statement to determine whether y has a value,
if y has no value and the x point is empty, you can refer to the following example:

<asp:Chart ID="Chart1" runat="server">  
    	<Series>  
    		<asp:Series Name="Testing" YValueType="Int32">  
    			<Points>  
    				<asp:DataPoint AxisLabel="Test 1" YValues="10" />  
    				<asp:DataPoint AxisLabel="Test 2" YValues=" " />  
    				<asp:DataPoint AxisLabel="Test 3" YValues="0" />  
    				<asp:DataPoint AxisLabel="Test 4" YValues="40" />  
    			</Points>  
    		</asp:Series>  
    	</Series>  
    	<ChartAreas>  
    		<asp:ChartArea Name="ChartArea1">  
    		</asp:ChartArea>  
    	</ChartAreas>  
    </asp:Chart>  

code behind:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        For Each series As System.Web.UI.DataVisualization.Charting.Series In Chart1.Series  
            For Each point As System.Web.UI.DataVisualization.Charting.DataPoint In series.Points  
                If point.YValues.Length > 0 AndAlso CDbl(point.YValues.GetValue(0)) = 0 Then  
                    point.LegendText = point.AxisLabel  
                    point.AxisLabel = String.Empty  
                    point.Label = String.Empty  
                End If  
            Next  
        Next  
End Sub
