Method Detail

addChartRenderer

public void addChartRenderer(AbstractChartRenderer render,
                             int z)

Adds a ChartRenderer with a specific z-coordinate.

Specified by:

addChartRenderer in interface Chart

Parameters:

render - the ChartRenderer

z - the z-coordinate, the highest coordinate is in front.

getChartRenderer

public java.util.Map<java.lang.Integer,AbstractChartRenderer> getChartRenderer()

Returns the Map of all ChartRenderers.

Specified by:

getChartRenderer in interface Chart

Returns:

a java.util.Map with all ChartRenderers

getChartRenderer

public AbstractChartRenderer getChartRenderer(int z)

Returns the ChartRenderer with a specific z-coordinate.

Specified by:

getChartRenderer in interface Chart

Parameters:

z - the z-coordinate

Returns:

the ChartRenderer or null.

getCoordSystem

public CoordSystem getCoordSystem()

Returns the coordinate system.

Specified by:

getCoordSystem in interface Chart

Returns:

a ClassicCoordSystem object or null if there is none.

getLegend

public Legend getLegend()

Returns this chart's legend.

Specified by:

getLegend in interface Chart

Returns:

the Legend object.

getTitle

public Title getTitle()

Returns the title for this chart.

Specified by:

getTitle in interface Chart

Returns:

a Title object.

getRowColorModel

public RowColorModel getRowColorModel()

Returns the RowColorModel for this chart. Note that this is simply the default row color model, and not necessarily the model used by all renderers.

Returns:

a RowColorModel object.

setChartRenderer

public void setChartRenderer(java.util.Map render)

Sets the Map with all ChartRenderers. The keys have to be the z-coordinates of the ChartRenderers.

Specified by:

setChartRenderer in interface Chart

Parameters:

render - a java.util.Map with all ChartRenderers.

setCoordSystem

public void setCoordSystem(CoordSystem c)

Sets the coordinate system for this chart, which can be null if the ChartRenderer doesn't need a coordinate system, e.g. if it's a PieChart.

Specified by:

setCoordSystem in interface Chart

Parameters:

c - the ClassicCoordSystem object

setLegend

public void setLegend(Legend l)

Sets the legend for this chart.

Specified by:

setLegend in interface Chart

Parameters:

l - the Legend

setTitle

public void setTitle(Title t)

Sets the title for this chart.

Specified by:

setTitle in interface Chart

Parameters:

t - the Title object

setRowColorModel

public void setRowColorModel(RowColorModel rcm)
                      throws java.lang.NullPointerException

Sets the RowColorModel for this chart. Also updates any renderers using the previous default model to this one.

Parameters:

rcm - the new RowColorModel

Throws:

java.lang.NullPointerException

setChartDataModel

public void setChartDataModel(ChartDataModel model)

Stores the ChartDataModel for this Chart.

Specified by:

setChartDataModel in interface Chart

Parameters:

model - the ChartDataModel

getChartDataModel

public ChartDataModel getChartDataModel()

Returns the ChartDataModel.

Specified by:

getChartDataModel in interface Chart

Returns:

the ChartDataModel for the Chart

setBounds

public void setBounds(java.awt.Rectangle r)

Sets the Bounds for this Chart. This is important for rendering the chart and always has to be done before rendering.

Specified by:

setBounds in interface Chart

Specified by:

setBounds in interface Renderer

Overrides:

setBounds in class AbstractRenderer

Parameters:

r - the Rectangle object defining this chart's bounds.

getBounds

public java.awt.Rectangle getBounds()

Returns the Bounds for the Chart.

Specified by:

getBounds in interface Chart

Specified by:

getBounds in interface Renderer

Overrides:

getBounds in class AbstractRenderer

Returns:

a Rectangle object defining this chart's bounds.

paintDefault

public void paintDefault(java.awt.Graphics2D g)

This method is called by the paint method to do the actual painting. The painting is supposed to start at point (0,0) and the size is always the same as the preferred size. The paint method performs the possible scaling.

Specified by:

paintDefault in class AbstractRenderer

Parameters:

g - the Graphics2D object to paint in.

render

public void render(java.awt.Graphics2D g)

Does the layout of the title, legend and coordinate system and calls the render method of all those including the ChartRenderers.

Specified by:

render in interface Chart

Specified by:

render in interface Renderer

Overrides:

render in class AbstractRenderer

Parameters:

g - the Graphics2D object to paint in.
