In this animation I use the function y=a*x, where parameter a changes from 0 to 3. In this example color of the function was defined using formula [1/(a+0.1), abs(sin(a)), 0.2].
The anim07.*.jvx files created by utility xvc2jvx were used as keyframes for JavaView animation. JavaView applet uses default parameters with
<param name=Animation.firstKey value=1>
<param name=Animation.lastKey value=21>
<param name="Animation.framesPerSecond" value=12>
