VisualFrame.setScale(scale)

Specifies the scale associated with this frame. The corresponding “getter” function is VisualFrame.getScale().

Parameter

scale

a Scale object

Example

Chart Component Script
dataset = [["State", "Quantity"], ["NJ",200], ["NY",300]]; (1)
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
var frame = new BrightnessColorFrame();
frame.setField("Quantity");
var scale = new LinearScale(); (2)
scale.setMax(325);
scale.setMin(175);
frame.setScale(scale); (3)
frame.setColor(java.awt.Color(0xff0000));
elem.setColorFrame(frame);
graph.addElement(elem);
1 See dataset to use a data block instead of an array literal.
2 Create the LinearScale object.
3 Use setScale to add the LinearScale to the BrightnessColorFrame.

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 and GraphElement.getColorFrame() ② to obtain a handle to the desired GraphElement and ColorFrame objects. For example:

var elem = graph.getElement(0); (1)
var frame = elem.getColorFrame(); (2)
// Compact syntax: var frame = graph.getElement(0).getColorFrame();

var scale = new LinearScale();
scale.setMax(325);
scale.setMin(175);
frame.setScale(scale);
