LabelForm.setCollisionModifier(value)

GraphForm

Specifies how collisions (labels occupying the same location) should be handled. The corresponding “getter” function is getCollisionModifier().

Parameter

value

One of the following constants:

VLabel.MOVE_NONE  // no adjustment
VLabel.MOVE_FREE  // move label any direction
VLabel.MOVE_RIGHT // move label right
VLabel.MOVE_UP    // move label up

Example

Chart Component Script

dataset = [["State","Quantity"], ["NJ",200], ["NY",300]]; (1)
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
var form1 = new LabelForm(); (2)
var form2 = new LabelForm(); (2)
form1.setLabel("label1");
form1.setValues(['NY', 100]);
form2.setLabel("label2");
form2.setValues(['NY', 100]);
form1.setCollisionModifier(VLabel.MOVE_FREE); (3)
graph.addForm(form1); (4)
graph.addForm(form2); (4)
graph.addElement(elem);

1	See dataset to use a data block instead of an array literal.
2	Create the LabelForm object.
3	Use `setCollisionModifier()` to allow free label movement.
4	Use EGraph.addForm(form) to add the `GraphForm` 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.
