I have wanted to do something similar, but within the limitations of
JavaSketchpad (no functions!). I accomplish this by making the function the
locus of points, which can be treated as an object. I have several examples in
MathTools; for example, see the Area Function applet at
http://www.mph.net/coelsner/jsp_applets/area_function.htm
The Geometer's Sketchpad source for this is
http://www.mph.net/coelsner/jsp_applets/area_function.gsp and instructions for
making the JavaSketchpad version is at
