StackRange

ScaleRange

The StackRange object computes the range by “stacking” the data values. To create a StackRange object, call the StackRange constructor.

var range = new StackRange();

Example

Chart Component Script

dataset = [["State", "Quantity"], ["NJ",200], ["NY",300]]; (1)
graph = new EGraph();
var qscale = new LinearScale("Quantity"); (2)
var elem = new IntervalElement("State", "Quantity");
qscale.setScaleRange(new StackRange()); // adds 200+300 (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 Scale object.
3	Create the StackRange object and assign to the `Scale`.
4	Use EGraph.setScale(field, scale) to add the `Scale` 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.
