You can create a transparent chart by setting the background-image attribute of the <DIV> which contains the chart.

The backgroundAlpha attribute in the <KoolChart> element tag must be set to display the background image which is defined in the container <DIV>.

<div id="chartHolder" style="width: 100%; height: 100%; background-image:url(/KoolChart/Assets/Images/background.jpg);"></div>
					
<KoolChart backgroundAlpha="0.1" ... >
