Method Detail

drawLine

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

Description copied from class: Line3DStrategy

Paints the connected series line in the specified Graphics context.

Overrides:

drawLine in class Line3DStrategy

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

AbstractChartSeries.setShowNullValues(boolean)

calculateSpline

protected Polygon3D calculateSpline(Polygon3D polygon)

Creates spline polygon (from simple polygon)

Parameters:

polygon -

Returns:

spline polygon

drawAndFill

protected void drawAndFill(AbstractGraphics g,
                           Polygon3D contour,
                           Polygon3D bottom,
                           boolean drawNulls,
                           Line3DSeries series,
                           ChartObjectsMap map,
                           HotSpotMap hotMap,
                           int index)

Draws 3D line

Parameters:

g -

contour - - lines top

bottom - - lines bottom

drawNulls - - if true - use SeriesPaintTags.NULL; if false - SeriesPaintTags.DEFAULT

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

map - lt.monarch.chart.engine.ChartObjectsMap

hotMap - lt.monarch.chart.engine.HotSpotMap

index - int

calculateSplinePoints

protected Point3D[] calculateSplinePoints(double[] x,
                                          double[] y,
                                          double[] z,
                                          int pointCount)

Calculate spline points. !!! Points size should be (pointCoint - 1)*(step+1) !!!

Parameters:

x -

y -

z -

pointCount -

Returns:

getStep

public int getStep()

Gets spline step number

Returns:

the step number

setStep

public void setStep(int step)

Sets the spline step number, i.e. how much lines should consist the line between two points.

Parameters:

step - line number between two data points

showNullPoints

protected boolean showNullPoints()

Description copied from class: Line3DStrategy

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).

Overrides:

showNullPoints in class Line3DStrategy

Returns:

boolean showing that null values should be drawn.
