Method Detail

getMarker

public final IlvMarker getMarker()

Returns the marker used to render data points.

See Also:

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

setMarker

public void setMarker(IlvMarker marker)

Sets the marker used to render data points.

See Also:

getMarker()

getMarkerSize

public final int getMarkerSize()

Returns the size of the marker.

Since:

JViews 5.5

See Also:

setMarkerSize(int)

setMarkerSize

public void setMarkerSize(int size)

Sets the size of the marker.

Parameters:

size - The new marker size. The actual size of the marker in pixel will be 2*size+1.

Since:

JViews 5.5

See Also:

getMarkerSize()

getMaxSize

public int getMaxSize()

Returns the maximum size of a marker.

Since:

JViews 8.0

getClipRect

public Rectangle getClipRect()

Returns the rectangle that will be used to clip this renderer drawing.

Overrides:

getClipRect in class IlvChartRenderer

See Also:

IlvChartRenderer.getPlotRect()

getPreferredMargins

public Insets getPreferredMargins()

Returns the preferred margins of this renderer for the calculation of the plotting rectangle.

If the isClipped() method returns false, the margins take into account the size of the marker.

                                      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.
