LineForm.setStartArrow(Boolean)

GraphForm

Specifies whether an arrow should be drawn at the start of the line (i.e., at the first point specified for the LineForm). The corresponding “getter” function is isStartArrow().

Parameter

Boolean: true: draw arrow
false: no arrow

Example

Chart Component Script

dataset = [["State", "Quantity"], ["NJ", 200], ["NY", 300]]; (1)
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
var form = new LineForm(); (2)
form.addPoint(new java.awt.Point(0,0));
form.addPoint(new java.awt.Point(100,100));
form.setStartArrow(true); (3)
form.setColor(java.awt.Color(0xff0000));
graph.addForm(form); (4)
graph.addElement(elem);

1	See dataset to use a data block instead of an array literal.
2	Create the LineForm object.
3	Use `setStartArrow()` to enable the start arrow.
4	Use EGraph.addForm(form) to add the `GraphForm` to the Chart.

Script that modifies the graph or dataset properties should be placed on the Chart component itself. See Add Component Script for more information. This script has access to the Chart data and Chart API methods. Scripted Charts are not good candidates for user-modification, so you should deselect ‘Enable Ad Hoc Editing’ in the Chart Properties dialog box.
