LineForm.addPoint(value)

GraphForm

Specifies the pixel location (integer values) or proportional location (fractional values) defining a point on the line. (Positive values specify distance from left/bottom. Negative values specify distance from right/top.)

Parameter

value: a subclass of java.awt.geom.Point2D
(e.g., java.awt.Point for pixels, java.awt.geom.Point2D.Double for proportion)

Example

Chart Component Script

dataset = [["State", "Quantity"], ["NJ", 200], ["NY", 300]]; (1)
graph = new EGraph();
var elem = new IntervalElement("State", "Quantity");
var form1 = new LineForm(); (2)
var form2 = new LineForm(); (2)
form1.addPoint(new java.awt.Point(100, 0)); (3)
form1.addPoint(new java.awt.Point(100, 200)); (3)
form1.addPoint(new java.awt.Point(200,100)); (3)
form1.setColor(java.awt.Color(0xff0000));
form2.addPoint(new java.awt.geom.Point2D.Double(.5,0)); (4)
form2.addPoint(new java.awt.geom.Point2D.Double(.5,.7)); (4)
form2.addPoint(new java.awt.geom.Point2D.Double(.7,.5)); (4)
form2.setColor(java.awt.Color(0xff00ff));
graph.addForm(form1); (5)
graph.addForm(form2); (5)
graph.addElement(elem);

1	See dataset to use a data block instead of an array literal.
2	Create the LineForm object.
3	Use `addPoint()` to set `form1` points in pixels.
4	Use `addPoint()` to set `form2` points proportionally.
5	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.
