Constructor Detail

SPCLinesExceedStrategy

public SPCLinesExceedStrategy(LineSeries measurementSeries,
                              LineSeries limitSeries,
                              boolean checkUpperLimitExceeding)

SPC line series strategy for showing where given measurement series is exceeding limit series data.

Parameters:

measurementSeries -

limitSeries -

checkUpperLimitExceeding - if true it checks if measurementSeries data is higher than limitSeries data, otherwise (false) - chekcs if measurement data is lower than given limitSeries data.

Method Detail

dispose

public void dispose()

Description copied from class: AbstractLineStrategy

Disposes the object

Specified by:

dispose in class AbstractLineStrategy<ChartProjector extends Projector>

getLinePointByX

public Point2D getLinePointByX(double x)

Description copied from class: AbstractLineStrategy

Calculates line Point2D value for a given x coordinate.

Overrides:

getLinePointByX in class AbstractLineStrategy<ChartProjector extends Projector>

Parameters:

x - coordinate for which the corresponding line point must be calculated.

Returns:

y calculated line value

determineLineDirection

protected void determineLineDirection()

Determines the direction of the line

isDataInverted

protected boolean isDataInverted()

Checks if the data of the line is inverted

Returns:

True if inverted

draw

public void draw(AbstractGraphics g,
                 ChartProjector projector,
                 PlaneMapper mapper,
                 HotSpotMap hotMap,
                 boolean showNullValues,
                 Style style,
                 java.lang.Object baseValue,
                 AbstractLineSeries<ChartProjector> series)

Description copied from class: AbstractLineStrategy

Draws the series in the chart area.

Overrides:

draw in class AbstractLineStrategy<ChartProjector extends Projector>

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,
                        AbstractLineSeries<ChartProjector> series)

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 - Chart series to which this strategy belongs

See Also:

AbstractChartSeries.setShowNullValues(boolean)

                               int n)

Forms a polygon which has to be drawn. Throws away not needed lines.

Parameters:

x - x point array

y - y point array

n - number of points

Returns:

new polygon

initDrawing

protected void initDrawing()

Initializes polygon arrays and other arrays. Also determines line direction

getStartIndex

protected int getStartIndex()

Gets the x value of the visible range end

Returns:

index of x value

getEndIndex

protected int getEndIndex()

Gets the x value of visible range start

binarySearch

@Deprecated
protected int binarySearch(java.lang.Object value)

Deprecated.

Gets the value

Returns:

index of x or y value

getPointPosition

protected Point2D getPointPosition(int markerIndex)

Computes the marker's specified by the index position.

Parameters:

                             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,

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.
