Constructor Detail

### CombinedDomainCategoryPlot

    public CombinedDomainCategoryPlot()

  Default constructor.

### CombinedDomainCategoryPlot

    public CombinedDomainCategoryPlot(CategoryAxis domainAxis)

  Creates a new plot.

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

Method Detail

### getGap

    public double getGap()

  Returns the space between subplots.

  Returns:
    The gap (in Java2D units).

### 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).

### 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).
