Constructor Details

CombinedDomainCategoryPlot

public CombinedDomainCategoryPlot()

Default constructor.

CombinedDomainCategoryPlot

public CombinedDomainCategoryPlot(CategoryAxis domainAxis)

Creates a new plot.

Parameters:

domainAxis - the shared domain axis (null not permitted).

Method Details

getGap

public double getGap()

Returns the space between subplots. The default value is 5.0.

Returns:

The gap (in Java2D units).

See Also:

• setGap(double)

setGap

public void setGap(double gap)

Sets the amount of space between subplots and sends a PlotChangeEvent to all registered listeners.

Parameters:

gap - the gap between subplots (in Java2D units).

See Also:

• getGap()

add

public void add(CategoryPlot subplot)

Adds a subplot to the combined chart and sends a PlotChangeEvent to all registered listeners.

The domain axis for the subplot will be set to null. You must ensure that the subplot has a non-null range axis.

Parameters:

subplot - the subplot (null not permitted).

add

public void add(CategoryPlot subplot,
 int weight)

Adds a subplot to the combined chart and sends a PlotChangeEvent to all registered listeners.

The domain axis for the subplot will be set to null. You must ensure that the subplot has a non-null range axis.

Parameters:

subplot - the subplot (null not permitted).

weight - the weight (must be >= 1).

remove

public void remove(CategoryPlot subplot)

Removes a subplot from the combined chart. Potentially, this removes some unique categories from the overall union of the datasets...so the domain axis is reconfigured, then a PlotChangeEvent is sent to all registered listeners.

Parameters:

subplot - the subplot (null not permitted).

getSubplots

public List getSubplots()

Returns the list of subplots. The returned list may be empty, but is never null.

Returns:

An unmodifiable list of subplots.

 Point2D source)

Returns the subplot (if any) that contains the (x, y) point (specified in Java2D space).

Parameters:

info - the chart rendering info (null not permitted).

source - the source point (null not permitted).

Returns:

A subplot (possibly null).

 double upperPercent,
 PlotRenderingInfo info,
 Point2D source)

Zooms in on the range axes.

Specified by:

calculateAxisSpace

protected AxisSpace calculateAxisSpace(Graphics2D g2,
 Rectangle2D plotArea)

Calculates the space required for the axes.

draw

public void draw(Graphics2D g2,

Overrides:

draw in class CategoryPlot

Parameters:

g2 - the graphics device.

area - the area within which the plot (including axis labels) should be drawn.

anchor - the anchor point (null permitted).

parentState - the state from the parent plot, if there is one.

info - collects information about the drawing (null permitted).

setFixedRangeAxisSpaceForSubplots

protected void setFixedRangeAxisSpaceForSubplots(AxisSpace space)

Sets the size (width or height, depending on the orientation of the plot) for the range axis of each subplot.

Parameters:

space - the space (null permitted).

setOrientation

public void setOrientation(PlotOrientation orientation)

getDataRange

public Range getDataRange(ValueAxis axis)

Returns a range representing the extent of the data values in this plot (obtained from the subplots) that will be rendered against the specified axis. NOTE: This method is intended for internal JFreeChart use, and is public only so that code in the axis classes can call it. Since, for this class, the domain axis is a CategoryAxis (not a ValueAxis) and subplots have independent range axes, the JFreeChart code will never call this method (although this is not checked/enforced).

Specified by:

axis - the axis.

Returns:

The range.
