javax.swing.table.AbstractTableModel

org.opensourcephysics.display.ComplexDataset

All Implemented Interfaces:

Data, Drawable, Measurable

public class ComplexDataset
extends javax.swing.table.AbstractTableModel
implements Drawable, Measurable, Data

ComplexDataset stores and plots a complex dataset (x,z) where the dependent variable has real and imaginary parts, z=(real, imaginary). In Re_Im mode, both the real and imaginary parts are shown as separate curves. In Phase mode, the vertical coordinate represents magnitude and color represents phase. ComplexDataset is Drawable and can be rendered on a DrawingPanel. ComplexDataset extends AbstractTableModel and can be rendered in a JTable.
