LinearRange

ScaleRange

The LinearRange object computes the range by using the minimum and maximum data values. To create a LinearRange object, call the LinearRange constructor.

var range = new LinearRange();

Example

Chart Component Script

dataset = [["State", "Quantity"],["NJ",-200],["NY",300]]; (1)
graph = new EGraph();
var qscale = new LinearScale("Quantity");
var elem = new IntervalElement("State", "Quantity");
range = new LinearRange(); (2)
qscale.setScaleRange(range); (3)
graph.setScale("Quantity", qscale); (4)
graph.addElement(elem);

1	See dataset to use a data block instead of an array literal.
2	Create the `LinearRange` object.
3	Use `setScaleRange` to assign the `LinearRange` to the LinearScale.
4	Use EGraph.setScale(field, scale) to add the Scale to the Chart.

LinearRange

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.
