Constructor Detail

BarPart

public BarPart(ChartModel model)

Constructs a new BarPart using the given ChartModel, the type STACK_TYPE_NOT_STACKED and a horizontal orientation.

Parameters:

model - The ChartModel that provides the data. null will be replaced by an empty ChartModel.

BarPart

public BarPart(ChartModel model,
               int stackType,
               int orientation)

Constructs a new BarPart using the given ChartModel, stack type and orientation.

Parameters:

model - The ChartModel that provides the data. null will be replaced by an empty ChartModel.

stackType - The type of the resulting graph. Specify one of STACK_TYPE_NOT_STACKED, STACK_TYPE_STACKED or STACK_TYPE_STACKED_PERCENT.

orientation - The orientation of the resulting graph. Specify HORIZONTAL or VERTICAL.

Method Detail

getRelativeColumnGap

public float getRelativeColumnGap()

Returns the relative gap of two side by side bars of succeeding columns. A gap of 1.0f is as wide as a bar. This parameter is only used in connection with the graph type STACK_TYPE_NOT_STACKED.

Returns:

The relative column gap, the default is 0.0f.

setRelativeColumnGap

public void setRelativeColumnGap(float gap)

Sets the relative gap of two side by side bars of succeeding columns. A gap of 1.0f is as wide as a bar. This parameter is only used in connection with the graph type STACK_TYPE_NOT_STACKED.

Parameters:

gap - The relative column gap.

getRelativeRowGap

public float getRelativeRowGap()

Returns the relative gap of two side by side bars of succeeding rows. A gap of 1.0f is as wide as a bar.

Returns:

The relative row gap, the default is 1.0f.

setRelativeRowGap

public void setRelativeRowGap(float gap)

Sets the relative gap of two side by side bars of succeeding rows. A gap of 1.0f is as wide as a bar.

Parameters:

gap - The relative column gap.

getValueLocation

public ValueLocation getValueLocation(int rowIndex,
                                      int columnIndex)

Description copied from class: GraphPart

Abstract function that calculates a ValueLocation for a given cell.

Overrides:

getValueLocation in class CartesianGraphPart

getLayout

public Layout getLayout(java.awt.Graphics g)

Description copied from interface: Part

Returns an instance of a layout that is able to report the bounds of this part and is able to paint this part.

Parameters:

g - The relevant graphics object.

Returns:

A layout that is able to report the bounds of this part and is able to paint this part. This method may also return null.

invalidate

public void invalidate()

Description copied from class: AbstractPart

Calls invalidate() on the chart context if it's not null.

Overrides:

invalidate in class AbstractPart
