Constructor Detail

AbstractGrid

public AbstractGrid(PlaneMapper mapper,
                    AxisMapper xMapper,
                    AxisMapper yMapper)

Abstract grid constructor

Parameters:

mapper - plane mapper

xMapper - x axis mapper

yMapper - y mapper

Method Detail

draw

public void draw(AbstractGraphics g)

Description copied from interface: ChartObject

Renders chart object on the Graphics context.

Parameters:

g - graphics context

drawGrid

protected abstract void drawGrid(AxisMapper axisMapper,
                                 int gridDepth,
                                 boolean isVerticalGrid,
                                 AbstractGraphics g,
                                 Projector projector,
                                 GeneralPoint ptt)

Draws the grid for the specified mapper

Parameters:

axisMapper - axis mapper

gridDepth - grid depth

isVerticalGrid - is the grid vertical

g - graphics context

projector - projector

ptt - Normalized point, to avoid point creation

getSortPosition

public int getSortPosition()

Description copied from interface: ChartObject

Returns chart object paint order index.

Specified by:

getSortPosition in interface ChartObject

Overrides:

getSortPosition in class AbstractChartObject<GridPaintTags>

Returns:

object paint order index

setXGridDepth

public void setXGridDepth(int xDepth)

Sets the grid depth. Depth defines how dense the grid should be, if several AxisScale objects are available.

Parameters:

xDepth - grid depth

setYGridDepth

public void setYGridDepth(int yDepth)

Sets the grid depth. Depth defines how dense the grid should be, if several AxisScale objects are available.

Parameters:

yDepth - grid depth

getProjector

public Projector getProjector()

Returns modified projector.

Returns:

projector

getYMapper

public AxisMapper getYMapper()

Returns the Y mapper that is set

Returns:

Returns the Y mapper.

getXMapper

public AxisMapper getXMapper()

Returns the X mapper that is set

Returns:

Returns the X mapper.

getYDepth

public int getYDepth()

Gets the y grid depth

Returns:

Returns the yDepth.

getXDepth

public int getXDepth()

Gets the x grid depth

Returns:

Returns the xDepth.

setPaintMode

public final void setPaintMode(PaintMode paintMode)

Sets grid painting mode. Possible values are: FILL_PAINT, HATCH_PAINT and GRADIENT_PAINT. FILL_PAINT for single color toFill-painting. GRADIENT_PAINT for cyclic (from start color to center color and from center color to start color) or acyclic (from start color to end color) gradient panel painting. By default the paint mode is set to FILL_PAINT.

Parameters:

paintMode - The paintMode to set.

getPaintMode

public final PaintMode getPaintMode()

Returns the paint mode of the grid

Returns:

Returns the paintMode.

copy

public void copy(AbstractGrid src)

Copies grid settings from source grid (style, depths)

Parameters:

src - source grid
