<font face="Myriad Pro">Dear Arnold,<br>
<br>
where should appear the arrowheads, if the line ends in: (-5,-5),
(-5,5), (5,-5), (-5,5) in the 4 CORNERS of your grid??? <br>
Inmidst of the circlepoint = not visible, due to the radius of the
circle...<br>
<br>
Just a general question: Why do you like to have arrowheads in a
functionplot? Any didactial aspects? I am definitely not used to that.
To show that the line does not end at that point?<br>
<br>
I always imagine when having an arrowhead, that there is a DIRECTION...
Just to widen my horizon of didactics.<br>
<br>
Regard,<br>
<br>

<div>Good ideas here. I would not thought of this solution.</div>

</div>
<div>One point: At my end, the lines don't have arrows at each end.
They're line segments.</div>

</div>
<div>Is there a fix for this?</div>

couldn't solve the problem with 2 arrowhead at the end of the lines
drawn, however the rest should work fine.<br>
