I am using .net 2008 frame work and Chart fx 6.2 version.
Chart control is rendered as image in browser. Though i changed the property of chart HTMLTAG to Flash, .net or SVG i could get only image as output in browser.
Find below the html code.
<ChartFX:Chart ID="Chart1" runat="server" CodePage="0" DesignTimeData="C:\Program Files\Chart FX DevStudio\ChartFX for .NET\Wizard\StepLines.txt"
EmbeddedData="False" Gallery="Step" Height="300px" HtmlTag="Flash" LineWidth="3"
MainClient="True" MarkerShape="None" NSeries="0" NValues="0" Width="300px">
</ChartFX:Chart>
