Ok, thank you very much for that, one more question, I'm trying to databind the pie chart to the sqldatasource, but it seems there are issues (or I'm not doing it right) with DataFieldY. The sqldatasource will return 2 column of data as follow:
Description cnt
7 Days 3
30 Days 37
Rest 42
24 Hour 116
Where the "Description" column I assign to "NameField" and "cnt" column I assign to DataFieldY. Below is my code for the chart.
<telerik:RadHtmlChart runat="server" ID="chartRouters" Width="100%" Height="100%" Transitions="true"
Skin="Silk" DataSourceID="sqlDSModem">
<ChartTitle Text="Router Status">
<Appearance Align="Center" Position="Top">
<TextStyle Color="White" />
</Appearance>
</ChartTitle>
<Legend>
<Appearance Position="Right" Visible="true">
</Appearance>
</Legend>
<PlotArea>
<Series>
<telerik:PieSeries StartAngle="90" DataFieldY="Cnt" NameField="Description">
<LabelsAppearance Position="OutsideEnd" DataFormatString="{0} %">
</LabelsAppearance>
<TooltipsAppearance Color="White" DataFormatString="{0} %"></TooltipsAppearance>
</telerik:PieSeries>
</Series>
</PlotArea>
</telerik:RadHtmlChart>
when I run the code, my pie chart looked "weird" and had only 4 lines (not the chart line, but lines extending out from a single point) Looks almost lilke it is not reading the "value" of the data.
When I go to the immediate window and do the :
?chartRouters.PlotArea.Series(0).DataFieldY(0), it gave me value of "c" and then 1 is "n" and 2 is "t". I was expecting to see the actual value when I do that, but it almost like is putting the column field name in the value instead of actual data value? That is weird.
What is wrong?
thank you!
