LineElement.setStackGroup(Boolean)

Specifies whether each subgroup receives an independent element (separate line), or whether a single element is used for all. Note: There is no corresponding “getter” function.

Parameters

Boolean

true: independent lines for each group
false: single line for all groups (default)

Example

Chart Component Script
dataset = [["State","Product","Quantity"],["NJ","P1",200],["NJ","P2",300],
["NY","P1",300],["NY","P2",100]]; (1)
graph = new EGraph();
var elem = new LineElement("State", "Quantity"); (2)
elem.setColorFrame(new CategoricalColorFrame("Product"));
elem.setStackGroup(true); (3)
graph.addElement(elem); (4)
1 See dataset to use a data block instead of an array literal.
2 Create the LineElement object.
3 Use setStackGroup to assign independent stack order.
4 Use EGraph.addElement(elem) to add the LineElement 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.

To change the property on a Chart that was previously created with the Chart Editor, use “getter” methods such as EGraph.getElement(index) ① to obtain a handle to the desired GraphElement object. For example:

var elem = graph.getElement(0); (1)
elem.setStackGroup(true);
