CategoricalLineFrame.setLine(val,line)

Assigns a line style to the specified value. The corresponding “getter” function is getLine(val). You can also set this using the bindingInfo.lineFrame.setLine property syntax in onRefresh script. See the Example 2 below.

Parameter

val

a data value

line

A GLine constant:

GLine.THIN_LINE
GLine.DOT_LINE
GLine.DASH_LINE
GLine.MEDIUM_DASH
GLine.LARGE_DASH

Example 1

Chart Component Script
dataset = [["State","Quantity"], ["NJ",200], ["NY",300]]; (1)
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
frame = new CategoricalLineFrame(); (2)
frame.setField("State"); (3)
frame.setLine('NJ',GLine.THIN_LINE); (4)
frame.setLine('NY',GLine.LARGE_DASH); (4)
elem.setLineFrame(frame); (5)
graph.addElement(elem);
1 See dataset to use a data block instead of an array literal.
2 Create the LineFrame object.
3 Use setField to specify the field for the CategoricalLineFrame.
4 Use setLine to set the line style for a value.
5 Use GraphElement.setLineFrame(frame) to add the LineFrame to the IntervalElement.

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 CategoricalLineFrame();
frame.setField("State");
frame.setLine('NJ',GLine.THIN_LINE);
frame.setLine('NY',GLine.LARGE_DASH);
elem.setLineFrame(frame);

Example 2

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

  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.setShapeField("Employee",Chart.STRING);
Chart1.bindingInfo.lineFrame = new CategoricalLineFrame;
Chart1.bindingInfo.lineFrame.setLine('Robert', GLine.LARGE_DASH);
Chart1.bindingInfo.lineFrame.setLine('Eric', GLine.LARGE_DASH);
Chart1.bindingInfo.lineFrame.setLine('Sue', GLine.DOT_LINE);
Chart1.bindingInfo.lineFrame.setLine('Annie', GLine.DOT_LINE);

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