StackRange.setGroupField(value)

ScaleRange

Determines the scale range from the stacked values of largest single group, based on the specified grouping field. The corresponding “getter” function is getGroupField().

Parameter

value: the field name, a String

Example

Chart Component Script

dataset = [["State", "Quantity"],["NJ",200],["NJ",100],["NY",400],["NY",300]]; (1)
graph = new EGraph();
var qscale = new LinearScale("Quantity"); (2)
var elem = new PointElement("State", "Quantity");
range = new StackRange(); (3)
range.setGroupField("State"); // max of 200+100, 400+300 (4)
qscale.setScaleRange(range); (5)
graph.setScale("Quantity", qscale); (6)
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.
4	Use `setGroupField` to compute the stacking based on the ‘State’ field.
5	Assign the `ScaleRange` to the `Scale`.
6	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.
