HeatColorFrame

The HeatColorFrame object contains a continuous color frame that returns varying shades of brown. To create a HeatColorFrame object, call the HeatColorFrame constructor.

importPackage(inetsoft.graph.aesthetic);
var frame = new HeatColorFrame('Quantity');

You can pass the name of a field (e.g., 'Quantity') to the constructor, or specify this later using the inherited VisualFrame.setField(field) property.

Bind a bar-type chart to the sample 'All Sales' query, with 'Company' (top 5) on the X-axis, and Sum(Total) on the Y-axis. Add the following script in the onLoad Handler.

importPackage(inetsoft.graph.aesthetic);
Graph1.bindingInfo.setColorField("Total",Chart.NUMBER);
Graph1.bindingInfo.colorFrame = new HeatColorFrame();

Example (Report or Viewsheet)

importPackage(inetsoft.graph)
importPackage(inetsoft.graph.element)
importPackage(inetsoft.graph.scale)
importPackage(inetsoft.graph.aesthetic)
importPackage(inetsoft.graph.data)

var arr = [["State", "Quantity"],
           ["NJ",200],["NY",300],["PA",50],["CT",100]];
dataset = new DefaultDataSet(arr);
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
var frame = new HeatColorFrame();
frame.setField("Quantity");
elem.setColorFrame(frame);

RainbowColorFrame

The RainbowColorFrame object contains a continuous color frame that returns colors of the rainbow. To create a RainbowColorFrame object, call the RainbowColorFrame constructor.

importPackage(inetsoft.graph.aesthetic);
var frame = new RainbowColorFrame('Quantity');

You can pass the name of a field (e.g., 'Quantity') to the constructor, or specify this later using the inherited VisualFrame.setField(field) property.

Example (Report)

Bind a bar-type chart to the sample 'All Sales' query, with 'Company' (top 5) on the X-axis, and Sum(Total) on the Y-axis. Add the following script in the onLoad Handler.

CategoricalColorFrame

The CategoricalColorFrame object contains a color frame that returns a distinct color for each unique value in the bound field. To create a CategoricalColorFrame object, call the CategoricalColorFrame constructor.

importPackage(inetsoft.graph.aesthetic);
var frame = new CategoricalColorFrame('State');

You can pass the name of a field (e.g., 'State') to the constructor, or specify this later using the inherited VisualFrame.setField(field) property.

Example (Report)

Bind a bar-type chart to the sample 'All Sales' query, with 'Company' (top 5) on the X-axis, and Sum(Total) on the Y-axis. Add the following script in the onLoad Handler.

importPackage(inetsoft.graph.aesthetic);
Graph1.bindingInfo.setColorField("Employee",Chart.STRING);
Graph1.bindingInfo.colorFrame = new CategoricalColorFrame;
