<div dir="ltr">Hi Qudsia,<div>I have run a test here using gsLineDashPattern and the resource worked as it is documented, so I am not sure why you are not seeing the desired results. What version of NCL are you running? Are all the polylines dashed? Are you seeing any error messages?</div><div><br></div><div>To answer your question about trajectories: No, there is no automatic way to curl the end of polylines. You can add additional X and Y points into gsn_polyline to get the desired effect though.</div><div><br></div><div>Finally, as we always tell everyone, please do not write individuals who respond to ncl-talk inquiries directly unless directed to do so.
