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");

elem.setHint(GraphElement.HINT_ALPHA,.8)

var sscale = new CategoricalScale("State");

var qscale = new LinearScale("Quantity");

var coord = new RectCoord(sscale,qscale);

var spec = new PlotSpec();

var logo = getImage("http://www.inetsoft.com/images/home/logo.gif");

spec.setBackgroundImage(logo);

coord.setPlotSpec(spec);

graph.setCoordinate(coord);

graph.addElement(elem);
