I would like to create my own vector plots, as opposed to using the vector template. The first part of this is straightforward in terms of drawing the lines:

loop(i,1,n) draw -n arrow$(i) -l {col(x)[i],col(y)[i],col(x)[i]+(col(dx)[i]*scale),col(y)[i]+(col(dy)[i]*scale)};

How do I at the arrow head to the end of the lines (the equivalent of selecting a line manually, at checking the box (arrow control: arrow at end). The way this is performed in origin leads me to believe the arrows and lines are the same object type, with a property toggle somewhere that I cannot find.

Thanks for the help,
