LevelRenderer()
Creates a new renderer with default settings. |
Method Summary | |
---|---|
protected double | calculateBarW0(CategoryPlot plot, PlotOrientation orientation, Rectangle2D dataArea, CategoryAxis domainAxis, CategoryItemRendererState state, int row, int column)
Calculates the coordinate of the first "side" of a bar. |
protected void | calculateItemWidth(CategoryPlot plot, Rectangle2D dataArea, int rendererIndex, CategoryItemRendererState state)
Calculates the bar width and stores it in the renderer state.
|
protected double | calculateSeriesWidth(double space, CategoryAxis axis, int categories, int series)
Calculates the available space for each series.
|
void | drawItem(Graphics2D g2, CategoryItemRendererState state, Rectangle2D dataArea, CategoryPlot plot, CategoryAxis domainAxis, ValueAxis rangeAxis, CategoryDataset dataset, int row, int column, int pass)
Draws the bar for a single (series, category) data item.
|
boolean | equals(Object obj)
Tests an object for equality with this instance.
|
double | getItemMargin()
Returns the item margin.
|
double | getMaximumItemWidth()
Returns the maximum width, as a percentage of the available drawing
space.
|
double | getMaxItemWidth()
Returns the maximum width, as a percentage of the available drawing
space.
|
CategoryItemRendererState | initialise(Graphics2D g2, Rectangle2D dataArea, CategoryPlot plot, int rendererIndex, PlotRenderingInfo info)
Initialises the renderer and returns a state object that will be passed
to subsequent calls to the drawItem method.
|
void | setItemMargin(double percent)
Sets the item margin and sends a RendererChangeEvent to all
registered listeners. |
void | setMaximumItemWidth(double percent)
Sets the maximum item width, which is specified as a percentage of the
available space for all items, and sends a RendererChangeEvent
to all registered listeners.
|
void | setMaxItemWidth(double percent)
Sets the maximum item width, which is specified as a percentage of the
available space for all items, and sends a RendererChangeEvent
to all registered listeners.
