There's nothing built-in. However you can modify the standard arrow
through inheritance, like this:<br>
<br>
from __future__ import division<br>
from visual import *<br>
<br>
class arrow2D(arrow):<br>
&nbsp;&nbsp;&nbsp; def __init__(self, pos=(0,0,0), axis=(1,0,0), color=color.white):<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; arrow.__init__(self, pos=pos, axis=(axis[0],axis[1],0),
color=color)<br>
<br>
arrow2D(pos=(0,0,0), axis=(3,4,2), color=color.red)<br>
arrow2D(pos=(3,4,2), axis=(5,-2,4), color=color.cyan)<br>

&nbsp;Dear all,<br>
  <br>
&nbsp;I am new in Vpython. I have a script that plots 3d vectors. By
default, it shows a plot in perspective 3D view. Is there a way to set
a display that will show my plot in plane projection?<br>
  <br>
thanks,<br>
