Class ComplexDataset

java.lang.Object
  javax.swing.table.AbstractTableModel
      org.opensourcephysics.display.ComplexDataset

All Implemented Interfaces:

Drawable, Measurable, java.io.Serializable, javax.swing.table.TableModel

public class ComplexDataset

extends javax.swing.table.AbstractTableModel

implements Drawable, Measurable

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.
