Class Curve

java.lang.Object

com.softwarefx.chartfx.server.galleries.Curve

All Implemented Interfaces:

IExtension, IGallery

public final class Curve
extends java.lang.Object
implements IExtension, IGallery

Provides access to the Curve gallery object.

Curve charts will use a spline algorithm to draw a curve between the points in the chart, rather than connecting the points directly with a straight line. Just as lines, curves also expose an extensive API to configure the curve color width and markers.

The methods of the Curve class allow you to customize the visual attributes of a Curve chart. In order to make the supported members available, you must first set the gallery of the chart to Curve, and cast the setGalleryAttributes method of the Chart to the Curve class:

• Java

• chart1.setGallery(Gallery.CURVE);
  Curve curve;
  curve = ((Curve)chart1.getGalleryAttributes());
  

The cast will fail if the gallery is not set to Curve.

Once you have done this, using the newly created object you can assign these special attributes for the Curve gallery type in your chart.

• PopulateCarProduction(chart1);

getTension

public float getTension()

Gets or sets the Tension variable for the Cubic Spline curve algorithm.

To access this method a CurvegetGalleryAttributesobject need to be created.

Using this method, you can create curves series drawn with 'loose' or 'tight' tension value. Think of the curve series as points connected by a rope. As you increase tension on the rope, the curves become more 'tight'. Decreasing the tension creates a more 'loose' looping curve.
