CategoricalColorFrame.setColor(val,color)

Assigns a color to the specified value. The corresponding “getter” function is CategoricalColorFrame.getColor(val).

Parameter

val

a data value

color

java.awt.Color to represent data value

Example 1

Chart Component Script
dataset = [["State","Quantity"], ["NJ",200], ["NY",300]]; (1)
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
frame = new CategoricalColorFrame(); (2)
frame.setField("State");
frame.setColor('NJ',java.awt.Color(0xff0000)); (3)
frame.setColor('NY',java.awt.Color(0xff00ff)); (3)
elem.setColorFrame(frame); (4)
graph.addElement(elem);
1 See dataset to use a data block instead of an array literal.
2 Create the ColorFrame object.
3 Use setColor to assign the indicated colors to ‘NJ’ and ‘NY’.
4 Use GraphElement.setColorFrame(frame) to add the ColorFrame 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.

To change the property on a Chart that was previously created with the Chart Editor, use “getter” methods such as EGraph.getElement(index) ① to obtain a handle to the desired GraphElement object. For example:

var elem = graph.getElement(0); (1)
frame = new CategoricalColorFrame();
frame.setField("State");
frame.setColor('NJ',java.awt.Color(0xff0000));
frame.setColor('NY',java.awt.Color(0xff00ff));
elem.setColorFrame(frame)

Example 2

This example illustrates how to use bindingInfo properties to control the ColorFrame.

  1. Bind a Bar Chart to the sample ‘All Sales’ Data Worksheet, with ‘Company’ (top 5) on the X-axis, and Sum(Total) on the Y-axis.

    The ‘All Sales’ Data Worksheet can be found in the Data Worksheet  Sample Queries folder. You may need to download the examples.zip file from GitHub into your environment. (This requires access to Enterprise Manager.) See Import and Export Assets for instructions on how to import.

  2. Add the following script in the onRefresh handler. (See Add Dashboard Script.)

    onRefresh Script
    Chart1.bindingInfo.setColorField("Employee",Chart.STRING);
Chart1.bindingInfo.colorFrame = new CategoricalColorFrame;
Chart1.bindingInfo.colorFrame.setColor("Robert",java.awt.Color.lightGray);
Chart1.bindingInfo.colorFrame.setColor("Sue",java.awt.Color(0x222222));

    CategoricalColorFrameSetColor

    Dashboard script that modifies bindingInfo should generally be placed in the onRefresh handler. See Add Dashboard Script.
