This is my code and is working fine

C#

<asp:Chart ID="chartColumn" runat="server" BackColor="WhiteSmoke" BackSecondaryColor="White"BackGradientStyle="TopBottom" BorderDashStyle="Solid" Palette="BrightPastel"
BorderColor="26, 59, 105" Height="460px" Width="530px" BorderWidth="2" ImageLocation="~/TempImages/ChartPic_#SEQ(300,3)">
<Legends><asp:Legend Name="Default" BackColor="Transparent" Font="Trebuchet MS, 8pt, style=Bold"
AutoFitMinFontSize="6" Docking="Top" LegendStyle="Table" ForeColor="Red"> </asp:Legend>
 </Legends><BorderSkin SkinStyle="Emboss"></BorderSkin> <Series> </Series>
<ChartAreas>
<asp:ChartArea Name="ChartArea1" BorderColor="64, 64, 64, 64" BorderDashStyle="Solid" BackSecondaryColor="White" BackColor="Gainsboro" ShadowColor="Transparent" BackGradientStyle="TopBottom">
 <Position Height="85" Width="90" X="4" Y="5" />
<AxisY LineColor="64, 64, 64, 64" IsLabelAutoFit="False"><LabelStyle Font="Trebuchet MS, 8.25pt, style=Bold" />
<MajorGrid LineColor="64, 64, 64, 64" />
</AxisY>
<AxisX LineColor="64, 64, 64, 64">
<LabelStyle Font="Trebuchet MS, 8.25pt, style=Bold" IntervalType="Auto" /><MajorGrid Interval="Auto" IntervalType="Auto" LineColor="64, 64, 64, 64" />
<MajorTickMark IntervalType="Auto" />
</AxisX>
</asp:ChartArea>
</ChartAreas>
</asp:Chart>

Method code behind

C#

public void FillChart(int DId)
    {
        // Set legend docking i.e position of the legends
        chartColumn.Legends["Default"].Docking = Docking.Bottom;
        // Set legend alignment
        chartColumn.Legends["Default"].Alignment = System.Drawing.StringAlignment.Center;
        // Set legend style Column / Row / Table
        chartColumn.Legends["Default"].LegendStyle = LegendStyle.Table;
        PID = Convert.ToInt32(ViewState["PatId"].ToString());
        CmsIdentity objIdentity = (CmsIdentity)Context.User.Identity;
        DataSet dsChart = new DataSet();
        clsPatientEPRResultsDb objResultDb = new clsPatientEPRResultsDb();
        
           dsChart = objResultDb.GetTestResultForChart(DId, PID, objIdentity.AccountInfoID, "");
          
        
        if (dsChart.Tables[0].Rows.Count > 0)
        {
            chartColumn.Visible = true;
            DataView dv = dsChart.Tables[0].DefaultView;
            seriesname = "Result";
            chartColumn.Series.Add(seriesname);
            chartColumn.Series[seriesname].ChartArea = "ChartArea1";
            chartColumn.Series[sername].ChartType =   SeriesChartType.Column;
            chartColumn.Series[sername].Palette = ChartColorPalette.BrightPastel;
            chartColumn.Series[seriesname].Name = seriesname;
            chartColumn.Series[seriesname].Color = System.Drawing.Color.Red;
            chartColumn.Series[seriesname].IsValueShownAsLabel = true;
            chartColumn.Series[seriesname].Points.DataBindXY(dv, "ResultDate1", dv, "Result");
            string CharPic = Server.MapPath("TempPDF/") + "Result(" + DateTime.Now.ToString("ddMMMyyyyhhmmss") + ").jpeg";
            chartColumn.SaveImage(CharPic, ChartImageFormat.Jpeg);
            chartColumn.Series[seriesname].Points.DataBindXY(dv, "ResultDate1", dv, "Result");
        } 
            
        
    }

Please see if this solves your problem, as i cannot see any problem in your code.

Solution 2

Add under handlers web.config:

 <handlers>
 <remove name="ChartImageHandler" />
 <add name="ChartImageHandler" precondition="integratedMode" verb="GET,HEAD">
       path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</add>

also check permissions

XML

<location path="ChartImg.axd">
   <system.web>
     <authorization>
       <allow users="*"/>
     </authorization>
   </system.web>
 </location>

If your page is only accessed by logged in user's or may be your folder access problem. Check both
