Scale.setFields(field)

Specifies the fields to which the Scale should be applied. The corresponding “getter” function is getFields().

Parameter

field: a String containing a column name

Example

Chart Component Script

dataset = [["State","Quantity"],["NJ",100],["NY",4000]]; (1)
graph = new EGraph();
var qscale = new LogScale(); (2)
var elem = new IntervalElement("State", "Quantity");
qscale.setFields(["Quantity"]); (3)
var coord = new RectCoord(new CategoricalScale("State"), qscale); (4)
graph.setCoordinate(coord); (5)
graph.addElement(elem);

1	See dataset to use a data block instead of an array literal.
2	Create the Scale object.
3	Use `setFields` to apply the `Scale` to the ‘Quantity’ field.
4	Use the `Scale` to create a new Coordinate.
5	Use EGraph.setCoordinate(coord) to add the `Coordinate` to the Chart.

ScaleFields

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.
