Thanks Anand, Alvaro and aant!
I�ve tried all suggested solutions but still no line will display itself on
the screen. I did not quite understand Anand what you ment by the line
"geom.setColor(1, setColor);". Is it possible for you to explain closer? And
I�m very happy for any new suggestions that will bring me closer to
displaying the line.
