Constructor Detail

IlvSinglePolylineRenderer

public IlvSinglePolylineRenderer()

Creates a new polyline renderer.

IlvSinglePolylineRenderer

public IlvSinglePolylineRenderer(IlvStyle style)

Creates a new polyline renderer, using the specified style.

Method Detail

getMarker

public final IlvMarker getMarker()

Returns the optional marker drawn by this renderer.

See Also:

setMarker(ilog.views.chart.graphic.IlvMarker)

setMarker

public void setMarker(IlvMarker marker)

Sets a marker on this renderer. The polyline renderer draws the associated marker for each projected data point. This marker is optional and can be set to null, in which case only the line joining the data points is drawn.

See Also:

setMarkerSize(int), setMarkerStyle(ilog.views.chart.IlvStyle)

getMarkerSize

public final int getMarkerSize()

Returns the size of the optional marker drawn by this renderer.

See Also:

setMarkerSize(int)

setMarkerSize

public void setMarkerSize(int size)

Sets the size of the optional marker drawn by this renderer.

See Also:

setMarker(ilog.views.chart.graphic.IlvMarker)

getMarkerStyle

public IlvStyle getMarkerStyle()

Returns the rendering style of the optional marker.

See Also:

getMarkerStyle()

setMarkerStyle

public void setMarkerStyle(IlvStyle style)

Specifies the rendering style of the optional marker. If no style is specified, the style of the renderer is used.

See Also:

setMarker(ilog.views.chart.graphic.IlvMarker)

isFilled

public boolean isFilled()

Indicates whether the renderer uses a fill color.

Overrides:

isFilled in class IlvSingleChartRenderer

Returns:

false.

Since:

JViews 5.5

has3DSupport

public boolean has3DSupport()

Indicates whether this renderer supports three-dimensional drawing.

Specified by:

has3DSupport in interface IlvChart3DSupport

Overrides:

has3DSupport in class IlvChartRenderer

Returns:

true

Since:

JViews 5.5

getDepths

public double[] getDepths()

Returns the front and back depths of the renderer.

Overrides:

getDepths in class IlvChartRenderer

Returns:

An array containing the front depth (minimum depth) and the back depth (maximum depth). The returned array is null if has3DSupport() returns false, or if the renderer is not added to a chart.

Since:

JViews 5.5

See Also:

IlvChart3DView.getFrontDepth(), IlvChart3DView.getBackDepth(), IlvChart3DView.setDepthGap(int)

getZAnnotationText

public String getZAnnotationText()

Returns the text displayed along the depth axis.

Overrides:

getZAnnotationText in class IlvSingleChartRenderer

Returns:

null if the renderer is a child of a stacked IlvPolylineChartRenderer. Otherwise, it returns the string computed by the IlvSingleChartRenderer.getDefaultLegendText() method.

Since:

JViews 5.5

See Also:

IlvChart3DView.setZAnnotationVisible(boolean)

get3DOutlinePaint

public Paint get3DOutlinePaint()

Returns the outline paint used when the renderer is drawn as a 3-D ribbon.

Returns:

The outline paint. The default paint is Color.black.

Since:

JViews 5.5

See Also:

set3DOutlinePaint(java.awt.Paint)

set3DOutlinePaint

public void set3DOutlinePaint(Paint p)

Sets the outline paint used when the renderer is drawn as a 3-D ribbon.

Parameters:

p - The outline paint. If set to null, no outline will be drawn.

Since:

JViews 5.5

computeDataLabelLocation

public Point computeDataLabelLocation(IlvDisplayPoint dp,
                                      Dimension size)

Computes the location of the data label associated with the specified point. This method is used by the IlvDataLabelAnnotation class.

Overrides:

computeDataLabelLocation in class IlvChartRenderer

Parameters:

dp - The considered display point.

size - The size of the label.

Returns:

The location of the center of the label.

IlvChartRenderer.setDataLabeling(int), IlvChartRenderer.setDataLabelLayout(int)

drawLegendSymbol

public void drawLegendSymbol(IlvLegendItem item,
                             Graphics g,
                             int x,
                             int y,
                             int w,
                             int h)

Draws the symbol of the given legend item. This method is called by IlvRendererLegendItem instances to draw the item symbol.

Overrides:

drawLegendSymbol in class IlvSingleChartRenderer

Parameters:

item - The legend item to draw.

g - The graphics context.

x - The symbol x-coordinate.

y - The symbol y-coordinate.

w - The symbol width.

h - The symbol height.
