I am having a problem getting a pie chart to render where there are only two seriesitems and one of the values is 0.
When a third series is added then it has no problems with one of them having a value of 0

<telerik:RadHtmlChart runat="server" ID="PieChart2" Width="420"Transitions="true">

<Appearance>

<FillStyle BackgroundColor="White" />

</Appearance>

<ChartTitle Text="CM Standard > Primary > Patients with No Pending Tasks">

<Appearance Align="Center" BackgroundColor="White" Position="Top" />

</ChartTitle>

<PlotArea>

<Appearance>

<FillStyle BackgroundColor="White" />

</Appearance>

<Series>

<telerik:PieSeries StartAngle="90">

<LabelsAppearance Position="Circle" DataFormatString="{0} %" />

<TooltipsAppearance DataFormatString="{0} %" />

<Items>

<telerik:SeriesItem BackgroundColor="#ff9900" Exploded="true" Name="Internet Explorer" YValue="18.3" />

<telerik:SeriesItem BackgroundColor="#cccccc" Exploded="false" Name="Firefox" YValue="35.8" />

<%--<telerik:SeriesItem BackgroundColor="#bbbbbb" Exploded="false" Name="Firefox" YValue="35.8" />--%>

</Items>

</telerik:PieSeries>

</Series>

</PlotArea>

<Legend>

<Appearance BackgroundColor="White" Position="Bottom" Visible="true"/>

</Legend>

</telerik:RadHtmlChart>

public void LoadChartData()

{

int totalpatients = Utilities.GetInt(ds.Tables[0].Rows[0]["TotalPatients"]);

int PatientsNoPendingTasks = Utilities.GetInt(ds.Tables[0].Rows[0]["PatientsNoPendingTasks"]);

int PatientsWithPendingTasks = Utilities.GetInt(ds.Tables[0].Rows[0]["PatientsWithPendingTasks"]);

int PatientsOverDueforCHA = Utilities.GetInt(ds.Tables[0].Rows[0]["PatientsOverDueforCHA"]);

int PatientsWithUpdatedCHA = totalpatients - PatientsOverDueforCHA;

PieSeries pieSeries = (PieSeries)PieChart2.PlotArea.Series[0];

PieChart2.PlotArea.Series[0].Items[0].Name = "No Pending Tasks";

PieChart2.PlotArea.Series[0].Items[0].YValue = 0;// PatientsNoPendingTasks;

PieChart2.PlotArea.Series[0].Items[1].YValue = 43;// PatientsNoPendingTasks;

PieChart2.PlotArea.Series[0].Items[1].Name = "Has Pending Tasks";

//PieChart2.PlotArea.Series[0].Items[2].YValue = 10;// PatientsNoPendingTasks;

//PieChart2.PlotArea.Series[0].Items[2].Name = "Test";

Hello Mark,

This issue has been fixed and it is not observed in the latest version of RadControls. Could you confirm the version of RadControls under which you are having the unexpected behaviour?

If it is observed in the latest official release (2012.3.1308), however, could you open a support ticket and attach a sample that reproduces the problem, so that we can do an investigation locally?

All the best,
