Constructor Details

CombinedRangeXYPlot

public CombinedRangeXYPlot()
Default constructor.

CombinedRangeXYPlot

public CombinedRangeXYPlot(ValueAxis rangeAxis)
Creates a new plot.
Parameters:
rangeAxis - the shared axis.

Method Details

add

public void add(XYPlot subplot)
Adds a subplot, with a default 'weight' of 1.

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

add

public void add(XYPlot subplot,
                int weight)
Adds a subplot with a particular weight (greater than or equal to one). The weight determines how much space is allocated to the subplot relative to all the other subplots.

You must ensure that the subplot has a non-null domain axis. The range axis for the subplot will be set to null.
Parameters:
subplot - the subplot.
weight - the weight (must be 1 or greater).

calculateAxisSpace

protected AxisSpace calculateAxisSpace(Graphics2D g2,
                                       Rectangle2D plotArea)
Calculates the space required for the axes.
Overrides:
calculateAxisSpace in interface XYPlot
Parameters:
g2 - the graphics device.
plotArea - the plot area.
Returns:
The space required for the axes.

clone

public Object clone()
            throws CloneNotSupportedException
Returns a clone of the plot.
Overrides:
clone in interface XYPlot
Returns:
A clone.

public void draw(Graphics2D g2,
                 Rectangle2D area,
                 Point2D anchor,
                 PlotState parentState,
                 PlotRenderingInfo info)
Draws the plot within the specified area on a graphics device.
Overrides:

Parameters:
g2 - the graphics device.
area - the plot area (in Java2D space).

source - the source point.
Returns:
A subplot (possibly null).
