LineElement

GraphElement

The LineElement object contains the visual elements for a line chart. To create a new LineElement object, call the LineElement constructor.

var elem = new LineElement("State", "Quantity");

You can pass one, two, or three field names (e.g., ‘State’, ‘Quantity’) to the constructor, or specify these later using the inherited GraphElement.addDim(field) and GraphElement.addVar(field) methods.

The following special methods are provided:

Example

Chart Component Script

dataset = [["State", "Quantity"], ["NJ", 100], ["NY", 300]]; (1)
graph = new EGraph();
var elem = new LineElement("State", "Quantity"); (2)
graph.addElement(elem); (3)

1	See dataset to use a data block instead of an array literal.
2	Create the `LineElement` object.
3	Use EGraph.addElement(elem) to add the `LineElement` to the Chart.

LineElement

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.
