GradientBackground (Chart FX for Java 8.0 API Specification)

java.lang.Object
- com.softwarefx.chartfx.server.adornments.GradientBackground

All Implemented Interfaces:: IBackgroundAdornment

public class GradientBackground
extends java.lang.Object
implements IBackgroundAdornment

The GradientBackground object allows changing the color to the chart's background, using a gradient.

In Chart FX, background gradients can be applied to two rectangular areas in the chart area: The chart's inside background (setPlotAreaBackground) and the main background (setChartBackground). Chart FX allows horizontal, vertical, diagonal and radial gradients when applying gradient fills to either of these areas of the chart.

To set the gradient colors, you can use the setColors, setColorFrom and setColorTo methods. When creating two color gradients, you can control the gradient brush using the setFactor and setPosition methods.

The following images show how gradients can be applied to the chart's backgound and plot area background:

Method Detail

getAngle

public float getAngle()

Sets the gradient angle when using the 'Angled' gradient background.

The setAngle method supports values ranging from 0 to 360 degrees.

You must select the 'Angled' type gradient when creating the GradientBackground object in order for this method to take effect.

The border chart gradient has been set to 45 degrees:

getColorFrom
```
public java.awt.Color getColorFrom()
```
Gets or sets the beginning color of a gradient.

This method sets the beginning color of a gradient. You can also set the beginning color of the gradient by utilizing the setColors method using index zero.
Set the starting color of the gradient object 'myGradient' to red:
Java
myGradient.setColorFrom(new java.awt.Color(255,0,0,255));

setColorFrom
```
public void setColorFrom(java.awt.Color value)
```
Gets or sets the beginning color of a gradient.

This method sets the beginning color of a gradient. You can also set the beginning color of the gradient by utilizing the setColors method using index zero.
Set the starting color of the gradient object 'myGradient' to red:
Java
myGradient.setColorFrom(new java.awt.Color(255,0,0,255));
Parameters:
value -

getColorTo
```
public java.awt.Color getColorTo()
```
Ending color of a gradient.

This method sets the ending color of a gradient. You can also set the ending color of the gradient by setting the last index of the setColors collection.
Set the ending color of the gradient object 'myGradient' to green:
Java
myGradient.setColorTo(new java.awt.Color(0,128,0,255));

setColorTo
```
public void setColorTo(java.awt.Color value)
```
Ending color of a gradient.

This method sets the ending color of a gradient. You can also set the ending color of the gradient by setting the last index of the setColors collection.
Set the ending color of the gradient object 'myGradient' to green:
Java
myGradient.setColorTo(new java.awt.Color(0,128,0,255));
Parameters:
value -

getColors

public java.util.List<java.awt.Color> getColors()

Gets or sets the colors to be used for a gradient background.

Java

GradientBackground myGradient;
myGradient = new GradientBackground(GradientType.RADIAL);
myGradient.getColors().set(0, new java.awt.Color(0,0,255,255));
myGradient.getColors().set(1, new java.awt.Color(255,255,255,255));

getEffectArea
```
public int getEffectArea()
```
Gets or sets a value indicating the percentage of chart area affected by a GradientBackground.
Java
myGradient.setEffectArea(50);

public java.util.List<java.lang.Float> getFactor()
```
Specifies the percentages of the starting color and the ending color to use at the corresponding position for two color gradients.

getPosition
```
public java.util.List<java.lang.Float> getPosition()
```
Gives access to a collection that allows you to specify positions along the gradient background to correspond with color and factor attributes.

getType

public GradientType getType()
