Examples of ptolemy.plot.Plot.addPoint()

ptolemy.plot.Plot.addPoint()
In the specified data set, add the specified x, y point to the plot. Data set indices begin with zero. If the data set does not exist, create it. The fourth argument indicates whether the point should be connected by a line to the previous point. Regardless of the value of this argument, a line will not drawn if either there has been no previous point for this dataset or setConnected() has been called with a false argument.
In order to work well with swing and be thread safe, this method actually defers execution to the event dispatch thread, where all user interface actions are performed. Thus, the point will not be added immediately (unless you call this method from within the event dispatch thread). All the methods that do this deferring coordinate so that they are executed in the order that you called them. @param dataset The data set index. @param x The X position of the new point. @param y The Y position of the new point. @param connected If true, a line is drawn to connect to the previouspoint.
