EGraph.clearElements()

Represent Multiple Measure to add multiple elements.

Removes all GraphElement and GraphForm objects from the chart. The inverse operations are EGraph.addElement(elem) and EGraph.addForm(form).

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();
form.addPoint(new java.awt.Point(0,0));
form.addPoint(new java.awt.Point(100,100));
form.addPoint(new java.awt.Point(200,100));
form.setFill(true);
graph.addForm(form); (2)
graph.addElement(elem); (3)
graph.clearElements(); (4)

1	See dataset to use a data block instead of an array literal.
2	Add LineForm object.
3	Add IntervalElement object.
4	Use `clearElements` to clear `LineForm` and `IntervalElement`.

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.
