Constructor Detail

Axis

public Axis(Chart<ST,S> chart,
            Axis.Direction direction,
            int index)

Constructor

Parameters:

chart - the Chart

direction - the axis direction (X or Y)

index - the y-axis index (not relevant for x-axes)

Method Detail

preparePaint

public void preparePaint()

paint

public void paint(java.awt.Graphics2D g)

Specified by:

paint in interface ChartPart

setDataType

public void setDataType(Series.DataType dataType)

getAxisTickCalculator

public AxisTickCalculator_ getAxisTickCalculator()

getBounds

public java.awt.geom.Rectangle2D getBounds()

Specified by:

getBounds in interface ChartPart

getYIndex

public int getYIndex()

getScreenValue

public double getScreenValue(double chartPoint)

Converts a chart coordinate value to screen coordinate. Same as AxisTickCalculators calculation.

Parameters:

chartPoint - value in chart coordinate system

Returns:

Coordinate of screen. eg: MouseEvent.getX(), MouseEvent.getY()

getScreenValueForMin

public double getScreenValueForMin()

getScreenValueForMax

public double getScreenValueForMax()

getChartValue

public double getChartValue(double screenPoint)

Converts a screen coordinate to chart coordinate value. Reverses the AxisTickCalculators calculation.

Parameters:

screenPoint - Coordinate of screen. eg: MouseEvent.getX(), MouseEvent.getY()

Returns:

value in chart coordinate system
