    I was having an issue with databound charts not displaying after upgrading the Telerik.Web.UI.dll from 2014.2.724.40 to 2015.2.623.40, so I decided to try just working with static html instead.  I borrowed some demo code and placed it in the same webpage in 2 different .NET projects:

              <telerik:RadHtmlChart runat="server" ID="PieChartXX" Width="700" Height="500" Transitions="true" Skin="Silk">
                  <ChartTitle Text="Browser Usage for April 2012">
                      <Appearance Align="Center" Position="Top"></Appearance>
                      <Appearance Position="Right" Visible="true"></Appearance>
                          <telerik:PieSeries StartAngle="90">
                              <LabelsAppearance Position="OutsideEnd" DataFormatString="{0} %"></LabelsAppearance>
                              <TooltipsAppearance Color="White" DataFormatString="{0} %"></TooltipsAppearance>
                                      <telerik:PieSeriesItem BackgroundColor="#ff9900" Exploded="true" Name="Internet Explorer" Y="18.3"></telerik:PieSeriesItem>
                                      <telerik:PieSeriesItem BackgroundColor="#cccccc" Exploded="false" Name="Firefox"  Y="35.8"></telerik:PieSeriesItem>
                                      <telerik:PieSeriesItem BackgroundColor="#999999" Exploded="false" Name="Chrome" Y="38.3"></telerik:PieSeriesItem>
                                      <telerik:PieSeriesItem BackgroundColor="#666666" Exploded="false" Name="Safari" Y="4.5"></telerik:PieSeriesItem>
                                      <telerik:PieSeriesItem BackgroundColor="#333333" Exploded="false" Name="Opera" Y="2.3"></telerik:PieSeriesItem>

    When I run the solution using the earlier version (2014.2) of the dll, I get what is shown in attached file RadHtmlChart-2014.2.724.40.jpg.  When I run using the upgraded version (2015.2), I get what is shown in RadHtmlChart-2015.2.623.40.jpg.  Can someone point me to where my problem(s) might be?  TIA

    Hi John,

    Is the issue related only to a data-binding scenario or a declarative setup as well? If the issue is data-binding specific then you should ensure to define the data source field types. Otherwise I would suggest the following:
        - Upgrade to the latest official version - 2016.1.113.
        - See whether there are some JavaScript errors. If so, try to fix them or provide us with the exact error messages.
        - If the issue is IE specific ensure you are not in compatibility mode.
        - Remove the CSS to see whether it is a CSS specific.

    If none of the above suggestions help it would be better to provide us with a runnable sample where the issue is reproduced, so that we can investigate it further.
