Hi

Is there something one should know when using the mschart libraries with Umbraco 4.7?

I'm used working with mschart in other projects but anyway here is what ive done so far

Implementation in web.config...

<configuration>
    <system.web>
        <pages>
            <controls>
                <!-- MSChart -->
                <add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
            </controls>
        </pages>
        <httpHandlers>
            <add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
        </httpHandlers>
    </system.web>
    <system.webServer>
        <handlers>
            <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
        </handlers>
    </system.webServer>
</configuration>

...and registered the assemblies

<assemblies>
    <add assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add assembly="System.Web.DataVisualization.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</assemblies>

Now, thats not so difficult

Added the chart to a c# usercontrol

<asp:Chart ID="Chart1" runat="server" Width="565" Height="300">
    <Series>
        <asp:Series Name="Series1">
        </asp:Series>
    </Series>
    <ChartAreas>
        <asp:ChartArea Name="ChartArea1">
        </asp:ChartArea>
    </ChartAreas>
</asp:Chart>

And for the fun of it I've added some data

protected void Page_Load(object sender, EventArgs e)
{
    Chart1.Series["Series1"].ChartType = SeriesChartType.Line;
 
    var q = _db.tblPROUserWeights.Where(x => x.UserId.Equals(7)).OrderBy(x => x.Week).Take(10);
 
    ChartArea chartArea1 = Chart1.ChartAreas["ChartArea1"];
    Series series1 = Chart1.Series["Series1"];
 
    chartArea1.AxisX.Interval = 1;
    chartArea1.AxisY.MajorGrid.Enabled = false;
    chartArea1.AxisX.MajorGrid.Enabled = false;
    chartArea1.BackGradientStyle = GradientStyle.TopBottom;
    chartArea1.BackColor = Color.BurlyWood;
    chartArea1.BackSecondaryColor = Color.BlanchedAlmond; 
 
    series1.XValueType = ChartValueType.Int32;
    series1.YValueType = ChartValueType.Int32;
 
    Chart1.DataSource = q;
    series1.XValueMember = "Week";
    series1.YValueMembers = "Weight";
    Chart1.DataBind();
}

When running this usercontrol in an external site, like an empty .NET Web Application it renders flawlessly, I'll attach an image so you can see.

Now, what on earth could be wrong and what is Umbracos problem with MSCharting?

Thanks
