<p>A bar graph plotter. This plotter contains an instance of the Plot
class from the Ptolemy plot package as a public member. Data at
the input, which can consist of any number of channels, are plotted
on this instance. Each input channel is plotted as a separate data set.
Each input token is an array of doubles.</p>
<p>
The <i>iterationsPerUpdate</i> parameter can be used to fine tune
the display. It can be quite expensive to generate the display, and
by default, this actor generates it on every firing. If
<i>iterationsPerUpdate</i> is set to some integer greater than
one, then it specifies how many iterations should be executed
between updates. Thus, if <i>iterationsPerUpdate</i> = 2, then every
second time this actor fires, it will update the display. That is,
it will update its display on the first firing, the third, the
fifth, etc. It will, however, consume its inputs on every firing.
The plot is always updated in the wrapup() method.</p>
