Constructor Detail

LineTrace

public LineTrace(float minx,
                 float maxx,
                 float miny,
                 float maxy)

Constructs a line trace.

Method Detail

getModel

public Graph2DModel getModel()

Gets the data sampled by this line trace.

setNumbering

public final void setNumbering(boolean flag)

Turns axis numbering on/off.

addNotify

public void addNotify()

Overrides:

addNotify in class java.awt.Canvas

setNumberFormat

public final void setNumberFormat(java.text.NumberFormat format)

Sets the display format used for axis numbering. Convenience method.

See Also:

setXNumberFormat(NumberFormat), setYNumberFormat(NumberFormat)

setXNumberFormat

public final void setXNumberFormat(java.text.NumberFormat format)

Sets the display format used for x-axis numbering.

setYNumberFormat

public final void setYNumberFormat(java.text.NumberFormat format)

Sets the display format used for y-axis numbering.

setXExtrema

public void setXExtrema(float min,
                        float max)

Sets the minimum/maximum values on the x-axis.

setYExtrema

public void setYExtrema(float min,
                        float max)

Sets the minimum/maximum values on the y-axis.

setSamplingInterval

public void setSamplingInterval(float interval)

Sets the sampling interval. Smaller values give a more accurate trace, but more susceptible to mouse noise.

clear

public void clear()

Clears the current trace.

setBounds

public final void setBounds(int x,
                            int y,
                            int width,
                            int height)

Reshapes the line trace to the specified bounding box.

Overrides:

setBounds in class java.awt.Component

getPreferredSize

public java.awt.Dimension getPreferredSize()

Returns the preferred size of this component.

Overrides:

getPreferredSize in class java.awt.Component

getMinimumSize

public java.awt.Dimension getMinimumSize()

Returns the minimum size of this component.

Overrides:

getMinimumSize in class java.awt.Component

offscreenPaint

protected void offscreenPaint(java.awt.Graphics g)

Paint the trace.

Specified by:

offscreenPaint in class DoubleBufferedCanvas
