Hi Rajeswari,

Thank you for contacting us.

I am sorry to say that RadHtmlChart doesn't support a 3D view. Such a feature request, however, has already been logged here, so that you can monitor its progress, comment it out and raise its priority for implementation by giving your vote to the item.

Regarding the "Data Set Binding", please refer to the HtmlChart - DataSet online demo for details.

I  am using Radhtml chart with Lineseries . I have two series. When the chart is renderes , I see a hand when I hover on the legend, When I click ton one of the series in the legend the chart disappears. I always want to display the two series, Idont want the legend to be clickable is it possible. I am not setting any min or maxvalue for Yaxis . I am doning a simple databind and set the properties in the aspx page. The lowest value in the dataset  is 268,000.  I am doing dataformat as follows But the yaxis label  shows starting from 0,100 ,200,300 and so on The yaxis label is not showing as thousands with thousand separator  , I want the Yaxis to be autoscaled .   <LabelsAppearance DataFormatString="{0:###,###}"  RotationAngle="0" /> I want a simple line chart with out any markers and labels and plot . I am attaching my code I want a simple line chart as the attachment of chart I created in excel
Thanks

Hi Rajeswari,

Please find my answers below:

  - Prevent series visibility switching when clicking on the legend. You can use the following code:

ASPX:

<script type="text/javascript">
    function OnLegendItemClick(args) {
        args.preventDefault();
    }
</script>
<telerik:RadHtmlChart runat="server" ID="RadHtmlChart2" Width="800px" Height="400px">
    <ClientEvents OnLegendItemClick="OnLegendItemClick" />
    <PlotArea>
        <Series>
            <telerik:ColumnSeries Name="In 2010">
                <SeriesItems>
                    <telerik:CategorySeriesItem Y="46.3" />
                    <telerik:CategorySeriesItem Y="46.5" />
                    <telerik:CategorySeriesItem Y="46.2" />
                    <telerik:CategorySeriesItem Y="46.4" />
                </SeriesItems>
            </telerik:ColumnSeries>
            <telerik:ColumnSeries Name="In 2011">
                <SeriesItems>
                    <telerik:CategorySeriesItem Y="42.8" />
                    <telerik:CategorySeriesItem Y="42.4" />
                    <telerik:CategorySeriesItem Y="42.2" />
                    <telerik:CategorySeriesItem Y="42.9" />
                </SeriesItems>
            </telerik:ColumnSeries>
        </Series>
        <XAxis>
            <Items>
                <telerik:AxisItem LabelText="January" />
                <telerik:AxisItem LabelText="Februrary" />
                <telerik:AxisItem LabelText="March" />
                <telerik:AxisItem LabelText="April" />
            </Items>
        </XAxis>
        <YAxis>
            <LabelsAppearance DataFormatString="{0}%" />
        </YAxis>
    </PlotArea>
    <ChartTitle Text="Firefox market share">
    </ChartTitle>
</telerik:RadHtmlChart>

   - y-axis formats - The mentioned formats are not supported by the chart. Please refer to the Formatting Numbers help article for the supported ones.
    - y-axis step label - You can use the YAxis.Step property in order to control the step.
    - Disable markers and labels - set the visible property of the markers and labelsappearance tags to false:

<telerik:LineSeries Name="In 2010">
    <MarkersAppearance Visible="false" />
    <LabelsAppearance Visible="false"></LabelsAppearance>
    <SeriesItems>
        <telerik:CategorySeriesItem Y="46.3" />
        <telerik:CategorySeriesItem Y="46.5" />
        <telerik:CategorySeriesItem Y="46.2" />
        <telerik:CategorySeriesItem Y="46.4" />
    </SeriesItems>
</telerik:LineSeries>
