All Implemented Interfaces:

java.io.Serializable, ChartObject, StyleEditorEntity

public class Axis2DY
extends Axis2D

Graphical representation of the Y coordinate axis of the 2D chart. Scrollable graphical representation of the Y coordinate axis of the 2D chart. Default implementation handles mouse dragging. A simple mouse click and drag is translated into an axis scroll. Ctrl + mouse drag select position of the axis for zooming. While Ctrl + mouse click unzooms the axis. These are the default event modifiers. The actual modifiers are specified in the stylesheet and "scrollModifiers" keys.

Constructor Detail

Axis2DY

public Axis2DY(AxisMapper mapper)

Constructs a new graphical representation of the Y coordinate axis of the 2D chart with the specified axis mapper.

Parameters:

mapper - the axis mapper

Axis2DY

public Axis2DY(AxisMapper mapper,
               MetaDataModel metaModel,
               DataModel dataModel)

Constructs a new graphical representation of the Y coordinate axis of the 2D chart with the specified axis mapper.

Parameters:

mapper - the axis mapper

metaModel - meta data model

dataModel - data model

Method Detail

prepare

public void prepare(AbstractGraphics g)

Prepares this axis for rendering.

Specified by:

prepare in class Axis2D

Parameters:

g - the Graphics context in which the axis will be painted

getWidth

public double getWidth()

Returns the width of area required to draw the axis.

Returns:

the axis width

getPreferredInsets

public java.awt.Insets getPreferredInsets()

Description copied from class: Axis2D

Queries preferred insets for the axis. Chart2D shrinks the chart area based on the inset information, collected from all axis objects, to make sure axis have enough space around the chart to draw all their labels correctly.

Overrides:

getPreferredInsets in class Axis2D

Returns:

Insets space, required between axis bounds and chart bounds.

drawTicksLabels

protected void drawTicksLabels(AbstractGraphics g,
                               LinearLabelLayouter layouter)

Prepares labels for drawing

Specified by:

drawTicksLabels in class Axis2D

Parameters:

g - graphics context

drawLabels

public void drawLabels(AbstractGraphics g,
                       LinearLabelLayouter layouter)

Description copied from class: Axis2D

Draws the labels of the axis in the specified Graphics context.

Specified by:

drawLabels in class Axis2D

Parameters:

g - the Graphics context in which the axis labels to paint

layouter - the Layouter used to layout axis labels

drawAxis

protected void drawAxis(AbstractGraphics g)

Description copied from class: Axis2D

Draws axis line

Specified by:

Parameters:

g - graphics context

setTitle

public void setTitle(int titleNr,
                     AxisTitle title)

Overrides:

protected void drawTitle(AbstractGraphics g,
                         LinearLabelLayouter layouter,
                         AxisTitle axisTitle)

Description copied from class: Axis2D

Draws the title of the axis and updates label layouter that is used to layout the axis labels. The layouter is updated by setting its visible range.

Specified by:
