public class ArrayPlotterXY extends Plotter implements SequenceActor
A plotter that plots a sequence of pairs of arrays of doubles as an XY plot. This plotter contains an instance of the Plot class from the Ptolemy plot package as a public member. Data at the inputs, which can have any number of channels, are plotted on this instance. Each pair of input channels is plotted as a separate data set. Each input token is an array of doubles.
The iterationsPerUpdate 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 iterationsPerUpdate is set to some integer greater than one, then it specifies how many iterations should be executed between updates. Thus, if iterationsPerUpdate = 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.
Note that this can be used to generate live plots, like XYScope, but it has fewer drawing artifacts than XYScope since it does not use XOR drawing mode.

initialize()
If the plot has not already been created, create it.
|
boolean |
postfire()
Read at most one token from each input channel on x and
y inputs, and if there is a token on both, plot the data
as an XY plot.
