I am using a chart control in an asp.net application. I drew 2 lines high and low by taking y coordinates in series 1 and series 2 but i am getting X And Y value of chart on tooltip. I want the tooltip value or x and y coordinate value in label on mouse move event.

i would like to emulate the functionality of finance.google.com

My code is as follows:

XML

<asp:Chart ID="Chart3" runat="server" DataSourceID="SqlDataSource1"Height="258px"uot;351px">
           <Series>
               <asp:Series ChartType="Line" Name="Series1" XValueMember="date"
                   XValueType="Date" YValueMembers="high" YValueType="Single"
                   ToolTip="#VALY,#VALX" MarkerImageTransparentColor="192, 192, 255"
                   MarkerStyle="Diamond">
                 </asp:Series>
               <asp:Series ChartType="Line" Name="Series2" XValueMember="date"
                   XValueType="Date" YValueMembers="low" YValueType="Single"
                   ToolTip="#VALY,#VALX" MarkerStyle="Diamond">

               </asp:Series>

           </Series>
           <ChartAreas>
               <asp:ChartArea Name="ChartArea1">
                   <AxisX IntervalType="Days">
                       <MajorGrid Enabled="False" />
                       <LabelStyle Interval="Auto" IntervalType="Days" />
                       <ScaleView SizeType="Days" />
                   </AxisX>
                   <AxisY>
                       <MajorGrid Enabled="False" />
                   </AxisY>
               </asp:ChartArea>
           </ChartAreas>
       </asp:Chart>

       <asp:SqlDataSource ID="SqlDataSource1" runat="server"
           ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
           SelectCommand="SELECT * FROM [score]"></asp:SqlDataSource>

use this property

LabelToolTip="Volumes(in million)"

or

ToolTip="Volumes(in million)"

in your code

XML

<asp:Series XValueMember="Days" YValueMembers="CashVolumn" ToolTip="Volumes(in million)"
                           IsValueShownAsLabel="true" LabelToolTip="Volumes(in million)" Name="Series1"
                           ChartType="Line" Color="Red" IsVisibleInLegend="true" BorderWidth="2">
                       </asp:Series>
                       <asp:Series Name="Series2" XValueMember="Days" YValueMembers="FTE" ToolTip="No of FTEs"
                           IsValueShownAsLabel="true" LabelToolTip="No of FTEs" ChartType="Line" YAxisType="Secondary"
                           IsVisibleInLegend="true" Color="BlueViolet" BorderWidth="2">
                       </asp:Series>

Solution 2

X axis is Time and Y axis is Temperature. I need to get the X and Y value when we click on Chart area. I am getting Y axis value , but X axis is showing zero.
