Max,

Thanks for your reply. I am just trying  to add a composite legend to my chart and make it customizable(like user can change the location and font style etc from a dialog).

 The problem is that the legend items are not getting displayed initially(as shown in the screen shots attached). I am actually adding the legend in the method where I create the histogram series but it still doesnt show. hence, I tried to add it in the fillscenegraph event. Please find below the piece of code where I'm creating the histogram series and adding it to the composite chart. I dont understand where am I going wrong.

Regards,

Uday
