Hi there,

I'm using Telerik RadControls for ASP.NET version v.2013.2.717.45 on Internet Explorer 8 using Visual Studio 2012.

I've been working on a RadHtmlChart that has 3 Column Series (stacked) and 1 Line Series. The Chart is databound and the data representation, as well as everything else, is working just fine for the chart. The only issue I have now is that when I added the Line Series to the Chart (thereby making the Chart a mixed series chart), there is a Jscript error when a user mouses over the Legend. The error is:

'options' is null or not an object

As soon as I remove the Line Series, the error goes away.

Any advice would be greatly appreciated!

Here is my RadHtmlChart:
