Examples of ptolemy.plot.EditablePlot$ModifyListener

ptolemy.plot.EditablePlot
This extension of Plot permits interactive modification of plotted data, one dataset at a time. By default, you can modify dataset number zero (the first one given). To change this default, call setEditable(). To edit a plot, use the right mouse button. Click and drag to the left to trace out new values for the data. To read back the modified data, use getData(). To undo a change to the data, type Control-Z. To redo the change, type Control-Y. The undo history is infinite.
The style of editing is very particular. This class assumes the data specify a function of x. I.e., there there is exactly one y value for every x value. Thus, with the right mouse button, you are allowed to trace out new y values starting with some leftmost x value. You can only trace values to the right. This feature makes it easy to trace values with discontinuities. Just start at the left, and drag to the right to the point of the discontinuity, then drag to the left, then right again. You will have to try it... Notice that this style of editing probably does not make sense with error bars, since there is no mechanism for editing the error bars.
To be able to modify the data in a dataset, of course, there must be data in the dataset. Thus, you should create a dataset (for example by calling addPoint()) before editing it. Only the visible part of the dataset can be edited (that is, the portion of the dataset along the visible part of the horizontal axis). If you zoom in, then, you can edit particular points more precisely.
To be notified when the user sketches a new signal, create an object that implements the EditListener interface and add that listener using addEditListener(). @author Edward A.
