Class IlvSimpleChartRenderer

java.lang.Object

ilog.views.chart.IlvChartRenderer

ilog.views.chart.renderer.IlvSimpleChartRenderer

All Implemented Interfaces:

IlvChartAreaAccessible, IlvChart3DSupport, Serializable

Direct Known Subclasses:

IlvTreemapChartRenderer

public abstract class IlvSimpleChartRenderer
extends IlvChartRenderer

The IlvSimpleChartRenderer is the base class for all atomic renderers of the entire data source. Such renderers implement the drawing of the entire data source by themselves, without dispatching the drawings of different data sets to different renderers.

Since:

JViews 7.5

Constructor Detail

IlvSimpleChartRenderer

protected IlvSimpleChartRenderer()

Creates a new IlvSimpleChartRenderer.

Method Detail

chartConnected

protected void chartConnected(IlvChart oldChart,
                              IlvChart newChart)

Called when the renderer is added to or removed from a chart.

Overrides:

chartConnected in class IlvChartRenderer

Parameters:

oldChart - The chart with which this renderer was associated, or null if this renderer is added to a new chart.

newChart - The chart to which this renderer is added, or null if this renderer is removed from its current chart.

makeDefaultStyle

protected IlvStyle makeDefaultStyle()

Creates a default style for this renderer.

getStyle

public IlvStyle getStyle()

Returns the main style used by this renderer.

See Also:

setStyle(ilog.views.chart.IlvStyle)

setStyle

public void setStyle(IlvStyle style)

Sets the main style used by this renderer. By default, the IlvTreemapChartRenderer class makes use of a single style. If the parameter is null and the renderer has been attached to a chart, sets a default style.

Note: The Bean property style must not be specified together with the Bean property styles.

See Also:

getStyle()

getStyles

public IlvStyle[] getStyles()

Returns the styles used by this renderer.

Specified by:

getStyles in class IlvChartRenderer

See Also:

getStyle()

setStyles

public void setStyles(IlvStyle[] styles)

Sets the styles used by this renderer.

Specified by:

setStyles in class IlvChartRenderer

See Also:

Note: The Bean property styles must not be specified together with the Bean property style.

getStyle

public IlvStyle getStyle(IlvDataSet dataSet,
                         int index)

This method is not supported by this renderer, because this renderer is associated with the entire data source, not with a single data set.

Specified by:

getStyle in class IlvChartRenderer

Parameters:

dataSet - The considered data set.

index - The index of the considered data point.

Returns:

The style used to display the point, or null if this data point is not displayed by the renderer.

Throws:

UnsupportedOperationException

draw

@Deprecated
public void draw(Graphics g,
                             IlvDataSet dataSet,
                             int iMin,
                             int iMax)

Deprecated. This method is not used by JViews.

This method is not supported by this renderer, because it is associated with the entire data source, not with a single data set.

Specified by:

draw in class IlvChartRenderer

Throws:

UnsupportedOperationException

Deprecated Since:

JViews 8.1

getBounds

public Rectangle2D getBounds(IlvDataSet dataSet,
                             int iMin,
                             int iMax,
                             Rectangle2D bounds,
                             boolean includeAnnotations)

Returns the bounds of the graphical representation for the specified data. If dataSet is not rendered by this renderer, an empty rectangle is returned. This method stores the result into bounds and returns bounds. If bounds is null, a new Rectangle2D is allocated.

This method always returns an empty rectangle, because this renderer is associated with the entire data source, not with a single data set.

Specified by:

getBounds in class IlvChartRenderer

Parameters:

dataSet - The data set containing the data points.

iMin - The minimum data point index.

iMax - The maximum data point index.

bounds - An optional rectangle used to store the result.

includeAnnotations - Indicates whether annotation bounds should be included.

drawSelectionHandles

public void drawSelectionHandles(Graphics g,
                                 IlvHandlesSelectionStyle style)

Draws this renderer with selection handles.

Specified by:

drawSelectionHandles in interface IlvChartAreaAccessible

Specified by:

drawSelectionHandles in class IlvChartRenderer

Parameters:

g - A graphics context.

style - The graphic style parameters.

Since:

JViews 8.8
