SizeFrame.setMax(value)

Specifies an arbitrary value representing the maximum allowable size for a graphical element. For SchemaElement and IntervalElement, the values specified for the SizeFrame.setLargest(value) and SizeFrame.setSmallest(value) properties are relative to the max value.

For example, if smallest=50 and max=100, the smallest value in the bound column is displayed at one half of the maximum allowable size. For PointElement and LineElement graphs, the max property is ignored. You can also set this using the bindingInfo.sizeFrame.max property syntax in onRefresh script. See Example 2 below. The corresponding “getter” function is getMax().

Parameter

value

Number of pixels, or relative size

Example 1

Chart Component Script
dataset = [["State", "Quantity", "width"], ["NJ", 200, 5],["NY", 300,10], ["PA",75,15]]; (1)
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
var frame = new LinearSizeFrame(); (2)
frame.setField("width"); (3)
frame.setSmallest(10);
frame.setLargest(50);
frame.setMax(100); (4)
elem.setSizeFrame(frame); (5)
graph.addElement(elem);
1 See dataset to use a data block instead of an array literal.
2 Create the LinearSizeFrame object.
3 Use the inherited VisualFrame.setField(field) property to assign the desired measure to the LinearSizeFrame.
4 Use setMax to fix the maximum at 100 pixels.
5 Use GraphElement.setSizeFrame(frame) to add the LinearSizeFrame 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 and GraphElement.getSizeFrame() ② to obtain a handle to the desired GraphElement and SizeFrame. For example:

var elem = graph.getElement(0); (1)
var frame = elem.getSizeFrame(); (2)
frame.setSmallest(10);
frame.setLargest(50);
frame.setMax(100);

Example 2

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

  1. Bind a Point 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.setSizeField("Total",Chart.NUMBER);
Chart1.bindingInfo.sizeFrame = new LinearSizeFrame;
Chart1.bindingInfo.sizeFrame.smallest = 10;
Chart1.bindingInfo.sizeFrame.largest = 50;
Chart1.bindingInfo.sizeFrame.max = 100;

    SizeFrameMax

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