The DrawLine Tool enables a user to draw lines on a TeeChart. Lines only have Pen characteristics, unlike the shapes you mention which have both Pen and Brush characteristics. I'm not sure I understand how you want the DrawLine Tool to draw anything other than lines. Could you please explain?Quant wrote: We require fill properties (like Fill Color/Pattern, Transparency %, etc.) of Drawline Tool for following shapes:
