Method Detail

renderDrag

public java.awt.Rectangle[] renderDrag(java.awt.Graphics g1,
                                       java.awt.Point p1,
                                       java.awt.Point p2)

Description copied from interface: DragRenderer

draws the drag for mousing from p1 to p2, and returns an array of Rectangles covering the rendering. If nothing is drawn, then an array of length zero should be returned, and nulls are allowed in the array. p1 and p2, and g are in the canvas frame of reference.

Specified by:

renderDrag in interface DragRenderer

Overrides:

renderDrag in class LabelDragRenderer

Parameters:

g1 - the graphics context for rendering

p1 - the click point

p2 - the current mouse position during drag and release.

Returns:

isShowReciprocalDeltaX

public boolean isShowReciprocalDeltaX()

setShowReciprocalDeltaX

public void setShowReciprocalDeltaX(boolean showReciprocal)

isShowSlope

public boolean isShowSlope()

true if the slope should be shown

Returns:

true if the slope should be shown

setShowSlope

public void setShowSlope(boolean showSlope)

true if the slope should be shown

Parameters:

showSlope - true if the slope should be shown

isShowFit

public boolean isShowFit()

true if the fit should be shown

Returns:

true if the fit should be shown

setShowFit

public void setShowFit(boolean showFit)

if true then show the fit for all but xlog,ylin.

Parameters:

showFit - if true then show the fit for all but xlog,ylin.

setNCycles

public void setNCycles(int i)

set the number to normalize the numbers by.

Parameters:

i -

getNCycles

public int getNCycles()

get the number to normalize the numbers by.

Returns:

the number of cycles, typically 1.
