Detailed Description

A renderer that draws a circle at each data point.

The renderer expects the dataset to be an XYZDataset. The XY values are the position of the ellipse; the Z is its diameter, in m.

April 28, 2004: Submitted in beta version (LEM)
May 9, 2006: Added support for a minimum display DBH (LEM)
February 4, 2008: Updated to conform to Java 6 compliance (LEM)
March 6, 2008: Added a separate argument for plot area, because it was not being calculated correctly when there had been zooming (LEM)

Constructor & Destructor Documentation

datavisualizer.XYTreeRenderer.XYTreeRenderer ( float  fLengthX,
float  fLengthY,
float  fXAxisLength,
float  fYAxisLength 
)

Constructs a new renderer.

Parameters:
fLengthX Visible plot length in the X direction. If zoomed, this may not match the whole plot length.
fLengthY Visible plot length in the Y direction. If zoomed, this may not match the whole plot length.
fXAxisLength Entire plot length, X direction
fYAxisLength Entire plot length, Y direction


Member Function Documentation

void datavisualizer.XYTreeRenderer.SetScaleFactor ( double  fScaleFactor  ) 

Sets the scale factor, which controls how large trees appear on the screen.

Parameters:
fScaleFactor double Scale factor.

double datavisualizer.XYTreeRenderer.GetScaleFactor (  ) 

Gets the scale factor, which controls how large trees appear on the screen.

Returns:
Scale factor.

dataArea - the area within which the data is being rendered.
info - collects drawing info.
plot - the plot (can be used to obtain standard color information etc).
domainAxis - the domain axis.
rangeAxis - the range axis.
dataset - the dataset.
series - the series index (zero-based).
item - the item index (zero-based).
crosshairState - crosshair information for the plot (null permitted).
pass - the pass index.

Object datavisualizer.XYTreeRenderer.clone (  )  throws CloneNotSupportedException

Returns a clone of the renderer, but not a good one.

Returns:
A clone.
Exceptions:
CloneNotSupportedException if the renderer cannot be cloned.


Member Data Documentation

final long datavisualizer.XYTreeRenderer.serialVersionUID = 1 [static, package]

Controls how large trees appear on the screen.

The minimum Z value to display.

The X axis length, whether or not the whole plot is being displayed.

This allows the renderer to scale the size of the tree circles.

The Y axis length, whether or not the whole plot is being displayed.

This allows the renderer to scale the size of the tree circles.
