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.

Field Detail

drag

protected boolean drag

Set to true when a rectangle is being dragged out by the mouse

userlimits

protected boolean userlimits

User limits. The user has set the limits using the mouse drag option

xaxis

protected Axis xaxis

Attached X Axis which must be registered with this class. This is one of the axes used to find the drag range. If no X axis is registered no mouse drag.

yaxis

protected Axis yaxis

Attached Y Axis which must be registered with this class. This is one of the axes used to find the drag range. If no Y axis is registered no mouse drag.

Constructor Detail

G2Dint

public G2Dint()

Method Detail

createXAxis

public Axis createXAxis()

Create Xaxis to be used for the drag scaling

createYAxis

public Axis createYAxis()

Create Yaxis to be used for the drag scaling

attachAxis

public void attachAxis(Axis a)

Attach axis to be used for the drag scaling. X axes are assumed to have Axis position Axis.BOTTOM or Axis.TOP. Y axes are assumed to have position Axis.LEFT or Axis.RIGHT.

Overrides:

attachAxis in class Graph2D

Parameters:

a - Axis to attach
