CR.6.13  CategoricalScale

The CategoricalScale object contains a nominal scale, i.e., a scale that logically maps nominal values to physical attributes. To create a CategoricalScale object, call the CategoricalScale constructor with the fields for which the scale should be generated.

var qscale = new CategoricalScale('State');

You can pass the names of the fields (e.g., 'State') for which the scale should be generated to the constructor, or specify these later using the inherited Scale.setFields(field) property.

Note: Script that modifies 'graph' should be placed at the element level. See Adding Element-Level Script in Report Scripting and Adding Component Script in Dashboard Scripting for more information.

Example (Report or Viewsheet)

dataset = [["State","Quantity"], ["NJ",200], ["NY",300]];

graph = new EGraph();

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

var sscale = new CategoricalScale("State");

var qscale = new LinearScale("Quantity");

var coord = new RectCoord(sscale, qscale);

coord.transpose();

graph.setCoordinate(coord);

graph.addElement(elem);
