Class Graph

java.lang.Object

com.day.cq.graphics.Graph

public class Graph
extends Object

The Graph class implements the basic functionality for the chart host object. This class is based on the former rgba/rgba_graph.c code.

The Graph object is the top level container of a chart graphic. It contains all the elements such as the axis, the data and the chart itself.

This object is not truly unmutable, but it is mostly write-once. That is, as soon as a property has been defined through its setter method, it cannot be changed again. It is completely in the responsability of the client not to tamper with any values after having calculated the graph. Moreover it is the clients duty to ensure complete setting of the graph and its component prior to drawing the chart. The results may not be as desired if failing to do so.

Constructor Details

Graph

public Graph(int width,
 int height,
 String type)

Creates a graph chart of the given width, height and type. The type parameter is used to create the chart object and depends on the Chart.getInstance(String) method. See there for a definition of this parameter.

Parameters:

width - The desired overall width of the graph chart

height - The desired overall height of the graph chart

type - The type of chart to draw. The value of this parameter is defined by Chart.getInstance(String).
