Direct Known Subclasses:: Contour

public class G2Dint
extends Graph2D

This class is an extension of Graph2D class.
It adds interactive selection of the plotting range and can display the mouse position in user coordinates.

Mouse Events

MouseDown: Starts the range selection
MouseDrag: Drag out a rectangular range selection
MouseUp: Replot with modified plotting range.

KeyDown Events

R: Redraw plot with default limits
r: Redraw plot using current limits
m: Pop window to enter manually plot range
c: Toggle pop-up window that displays the mouse position in user coordinates
d: Show coordinates of the closest data point to the cursor
D: Hide data coordinates pop-window
h: This key pressed in Any pop-window at any-time will hide it.

Note: To hide Any pop-window press the key h in the window. This will hide the window at any time. Depending on your windowing system the mouse button might have to be pressed in the popup window to ensure it has the keyboard focus.
