Style Chart API - Object Hierarchy

The figure below shows the object structure of the Style Intelligence charting API. Among the significant objects, GraphElement contains the elements that graphically represent data (lines, bars, etc.). VisualFrame contains information about mapping data dimensions to physical properties (size, color, etc.), and Scale contains the scaling information for such mappings. GraphForm contains information for manually-drawn chart objects.

Getting and Setting Chart Properties

The Chart API provides getter and setter methods that allow you to read and write most chart properties from script. This following section provides definitions and examples for the setter methods.

In general, you can call the getter method corresponding to a particular setter method by simply changing the method name prefix. For example, the getter method corresponding to LabelForm.setAlignmentY() is LabelForm.getAlignmentY().

The following script illustrates how you can get the alignment of one chart component, and use it to set the alignment of another:

importPackage(inetsoft.graph)
importPackage(inetsoft.graph.element)
importPackage(inetsoft.graph.scale)
importPackage(inetsoft.graph.aesthetic)
importPackage(inetsoft.graph.data)
importPackage(inetsoft.graph.coord)
importPackage(inetsoft.graph.guide.form)
 
var arr = [["State","Quantity"], ["NJ",200], ["NY",300]];
dataset = new DefaultDataSet(arr);
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
var form1 = new LabelForm();
var form2 = new LabelForm();
form1.setLabel("label1");
form1.setPoint(new java.awt.Point(100, 100));
form1.setAlignmentY(GraphConstants.TOP_ALIGNMENT);
form2.setLabel("label2");
form2.setPoint(new java.awt.Point(200, 100));
form2.setAlignmentY(form1.getAlignmentY());
graph.addForm(form1);
graph.addForm(form2);
graph.addElement(elem);
