public class ColorGradientAxis
extends DefaultNumericAxis

An Axis with a color gradient e.g. for use with HeatMap plots. By default this axis is excluded from the Zoomer Plugin. TODO: - Fix LEFT, CENTER_HOR/VERT - Reduce Boilerplate Code - Allow free Positioning? e.g legend style, outside of chart, ...

Method Detail

colorGradientProperty

public javafx.beans.property.ObjectProperty<ColorGradient> colorGradientProperty()

Color gradient (linear) used to encode data point values.

Returns:

gradient property

computePrefHeight

protected double computePrefHeight(double width)

Description copied from class: AbstractAxis

Computes the preferred height of this axis for the given width. If axis orientation is horizontal, it takes into account the tick mark length, tick label gap and label height.

Overrides:

computePrefHeight in class AbstractAxis

Returns:

the computed preferred width for this axis

computePrefWidth

protected double computePrefWidth(double height)

Description copied from class: AbstractAxis

Computes the preferred width of this axis for the given height. If axis orientation is vertical, it takes into account the tick mark length, tick label gap and label height.

Overrides:

computePrefWidth in class AbstractAxis

Returns:

the computed preferred width for this axis

drawAxis

public void drawAxis(javafx.scene.canvas.GraphicsContext gc,
                     double axisWidth,
                     double axisHeight)

Description copied from interface: Axis

Function allows custom drawing of axes outside the Axis environment (ie. on another canvas)

Specified by:

drawAxis in interface Axis

Overrides:

drawAxis in class AbstractAxis

Parameters:

gc - the graphic context on which the axis is to be drawn

axisWidth - the axis width in pixel (N.B. padding is being added)

axisHeight - the axis height in pixel (N.B. padding is being added)

drawAxisLine

protected void drawAxisLine(javafx.scene.canvas.GraphicsContext gc,
                            double axisLength,
                            double axisWidth,
                            double axisHeight)

Overrides:

drawAxisLine in class AbstractAxis

getColor

public javafx.scene.paint.Color getColor(double value)

Parameters:

value - z-Value, values outside of the visible limit are clamped to the extrema

Returns:

the color representing the input value on the z-Axis

getColorGradient

public ColorGradient getColorGradient()

Returns the value of the colorGradientProperty().

Returns:

the color gradient used for encoding data values

getGradientWidth

public double getGradientWidth()

getIntColor

public int getIntColor(double value)

Return the color for a value as an integer with the color values in its bytes. For use e.g. with an IntBuffer backed PixelBuffer.

Parameters:

value - z-Value

Returns:

integer with one byte each set to alpha, red, green, blue

gradientWidthProperty

public javafx.beans.property.DoubleProperty gradientWidthProperty()

setColorGradient

public void setColorGradient(ColorGradient value)

Sets the value of the colorGradientProperty().

Parameters:

value - the gradient to be used

setGradientWidth
