Constructor Detail

PiePlotState

public PiePlotState(PlotRenderingInfo info)

Creates a new object for recording temporary state information for a renderer.

Parameters:

info - the plot rendering info.

Method Detail

getPassesRequired

public int getPassesRequired()

Returns the number of passes required by the renderer.

Returns:

The number of passes.

setPassesRequired

public void setPassesRequired(int passes)

Sets the number of passes required by the renderer.

Parameters:

passes - the passes.

getTotal

public double getTotal()

Returns the total of the values in the dataset.

Returns:

The total.

setTotal

public void setTotal(double total)

Sets the total.

Parameters:

total - the total.

getLatestAngle

public double getLatestAngle()

Returns the latest angle.

Returns:

The latest angle.

setLatestAngle

public void setLatestAngle(double angle)

Sets the latest angle.

Parameters:

angle - the angle.

getPieArea

public java.awt.geom.Rectangle2D getPieArea()

Returns the pie area.

Returns:

The pie area.

setPieArea

public void setPieArea(java.awt.geom.Rectangle2D area)

Sets the pie area.

Parameters:

area - the area.

getExplodedPieArea

public java.awt.geom.Rectangle2D getExplodedPieArea()

Returns the exploded pie area.

Returns:

The exploded pie area.

setExplodedPieArea

public void setExplodedPieArea(java.awt.geom.Rectangle2D area)

Sets the exploded pie area.

Parameters:

area - the area.

getPieCenterX

public double getPieCenterX()

Returns the x-coordinate of the center of the pie chart.

Returns:

The x-coordinate (in Java2D space).

setPieCenterX

public void setPieCenterX(double x)

Sets the x-coordinate of the center of the pie chart.

Parameters:

x - the x-coordinate (in Java2D space).

getPieCenterY

public double getPieCenterY()

Returns the y-coordinate (in Java2D space) of the center of the pie chart. For the PiePlot3D class, we derive this from the top of the pie.

Returns:

The y-coordinate (in Java2D space).

setPieCenterY

public void setPieCenterY(double y)

Sets the y-coordinate of the center of the pie chart. This method is used by the plot and typically is not called directly by applications.

Parameters:

y - the y-coordinate (in Java2D space).

getLinkArea

public java.awt.geom.Rectangle2D getLinkArea()

Returns the link area. This defines the "dog-leg" point for the label linking lines.

Returns:

The link area.

setLinkArea

public void setLinkArea(java.awt.geom.Rectangle2D area)

Sets the label link area. This defines the "dog-leg" point for the label linking lines.

Parameters:

area - the area.

getPieHRadius

public double getPieHRadius()

Returns the vertical pie radius.

Returns:

The radius.

setPieHRadius

public void setPieHRadius(double radius)

Sets the vertical pie radius.

Parameters:

radius - the radius.

getPieWRadius

public double getPieWRadius()

Returns the horizontal pie radius.

Returns:

The radius.

setPieWRadius

public void setPieWRadius(double radius)

Sets the horizontal pie radius.

Parameters:

radius - the radius.
