Whether or not this works is going to depend on which screen-device
you are using, but with "xwin" you should be able to do this by
calling plflush() between each vector plotting operation.
init-plot()
loop {
calculate-new-vector
plot-vector
plflush
}
plend()
In the end you will have all the vectors displayed on the plot. If
you only want to display the latest vector you should call plclear()
before plot-vector.
Not all of the screen-device drivers support plflush() and/or plclear().
