Constructor Detail

Line3DStrategy

public Line3DStrategy()

Line3D strategy constructor

Method Detail

dispose

public void dispose()

Description copied from class: AbstractLine3DStrategy

Disposes the object

Specified by:

dispose in class AbstractLine3DStrategy

isDataInverted

protected boolean isDataInverted()

Checks if the data of the line is inverted

Returns:

True if inverted

draw

public void draw(AbstractGraphics g,
                 Projector projector,
                 PlaneMapper3D mapper,
                 HotSpotMap hotMap,
                 boolean showNullValues,
                 Style style,
                 java.lang.Object baseValue,
                 Line3DSeries series)

Description copied from class: AbstractLine3DStrategy

Draws the series in the chart area.

Overrides:

draw in class AbstractLine3DStrategy

Parameters:

g - graphics context

projector - projector instance

mapper - plane mapper

hotMap - hot spot map

showNullValues - boolean value indicating whether to show the null values

style - style object

baseValue - base value

series - scatter series instance

drawLine

protected void drawLine(AbstractGraphics g,
                        Line3DSeries series,
                        HotSpotMap hotMap)

Paints the connected series line in the specified Graphics context.

Parameters:

g - the Graphics context in which to paint the series line. NOTE: setShowNullValues(boolean) works a little different here. When set to true, the line is broken and started from the next non-null point value. When set to false, the null values are simply ignored: the line connects all non-null value points.

series - lt.monarch.chart.chart3D.series.Line3DSeries

hotMap - lt.monarch.chart.engine.HotSpotMap

See Also:

AbstractChartSeries.setShowNullValues(boolean)

initDrawing

protected void initDrawing()

Initializes polygon arrays and other arrays Also determines line direction

buildSeriesPolygons

protected int buildSeriesPolygons(Polygon3D[] linePolygon,
                                  double[] firstX,
                                  double[] lastX,
                                  Polygon3D[] bottomPolygon,
                                  boolean drawNulls)

Builds polygons that are used to render series line and toFill it's area if toFill color is set.

Parameters:

linePolygon - array of polygons that forms series polyline

firstX - array of series segments start positions [0;1]

lastX - array of series segments end positions [0;1]

bottomPolygon - array of polygons that forms bottom polyline of series area

drawNulls - declares when to calculate values and build polygons for null values in data model.

Returns:

number of polygons that forms series line

getPointPosition

protected Point3D getPointPosition(int markerIndex)

Computes the marker's specified by the index position.

Parameters:

markerIndex - index of the marker to compute position for

projectPolygon

                             double[] firstX,
                             double[] lastX,
                             Polygon3D[] bottomPolygon,
                             int pi)

Forms a new polygon if previous polygon contains at least one point

Parameters:

polygon - Line polygon array

firstX - First point array

lastX - Last point array

bottomPolygon - Bottom line polygon array

pi - Count of the polygons currently in polygon array

Returns:

Returns count of current line polygon

getDataValueMappingHeight

protected double getDataValueMappingHeight(java.lang.Object value,
                                           int index)

Gets value of data height

Parameters:

value - value of Object

index - number in array of object

Returns:

double value of data height

isStacked

protected boolean isStacked()

Checks if the data model is stacked

Returns:

true if data model is stacked on something

showNullPoints

protected boolean showNullPoints()

Checks and returns if user has set nullLineColor or nullFillColor objects. This means that user would like to see the probable values instead of nulls (if it is possible).

Returns:

boolean showing that null values should be drawn.

setLineWidth

public void setLineWidth(double width)

getLineWidth

public double getLineWidth()

appendSeriesRectangles

protected void appendSeriesRectangles(Line3DSeries series,
