Currently labels of SeriesItems with values greater or equal to the YAxis MaxValue are being cut: When chart title is not set. AND the labels position is set to Above for AreaSeries, LineSeries, ScatterSeries and ScatterLineSeries. OR the labels position is set to outsideEnd for ColumnSeries. In FireFox, Opera and WebKit browsers. For the time being the chart title can be set with space character.
Rejected with the following comment - Labels are cut because there is no top margin of the plot area. You can manually set it: <telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Width="600" Height="400"> <PlotArea> <YAxis MaxValue="25"></YAxis> <Appearance> <TextStyle Margin="10 0 0 0" /> </Appearance> <Series> <telerik:ColumnSeries Name="Series 1"> <SeriesItems> <telerik:CategorySeriesItem Y="30" /> <telerik:CategorySeriesItem Y="10" /> <telerik:CategorySeriesItem Y="20" /> </SeriesItems> </telerik:ColumnSeries> </Series> </PlotArea> </telerik:RadHtmlChart>
