Hi,
Does anyone who knows how to use Geogebra within LON-CAPA know how to do this?
I am trying to make a functionplotresponse question that requires students to
draw a vector pointing straight up from and attached to the x-axis, but without
drawing an explicit attachment point on the axis.
If I use this approach it works, but the vector tail attaching point is plotted
and visible:
<functionplotelements>
<plotobject label="F1a_tail" x="6" y="0" />
<plotvector label="F1a" tailx="7" taily="1" tipx="8" tipy="1" />
...
</functionplotelements>
<functionplotruleset>
<functionplotvectorrule index="Harmonic_1a" vector="F1a" angle="90"
angleerror="2" tailpoint="F1a_tail" length="11" lengtherror="0.5" />
</functionplotruleset> on the graph:
Here is the result:
[cid:image005.jpg@01D397A0.2AA69C80]
If I change "F1a_tail" in the above code to "(6,0)" it does not work:
[cid:image006.jpg@01D397A0.2AA69C80]
Is there a way I can specify a tail attachment point without showing it on the
graph?
Thanks,
