PolarCoord.setCoordinate(coord)

Coordinate

Polar Coordinates for a walkthrough of polar coordinates.

Specifies the RectCoord on which the polar coordinates should be based. The corresponding “getter” function is getCoordinate().

Parameter

coord: a RectCoord object

Example

Chart Component Script

dataset = [["Direction", "Score"], [(Math.PI/2),20], [(Math.PI/4),30], [(Math.PI),35]]; (1)
graph = new EGraph();
var elem = new PointElement("Direction", "Score");
var xscale = new LinearScale("Direction");
var yscale = new LinearScale("Score");
yscale.setMin(0);
yscale.setMax(40);
xscale.setMin(0);
xscale.setMax(1.95*Math.PI);
xscale.setIncrement(Math.PI/8);
var rect = new RectCoord(xscale,yscale); (2)
var polar = new PolarCoord(); (3)
polar.setCoordinate(rect); (4)
graph.setCoordinate(polar); (5)
graph.addElement(elem);

1	See dataset to use a data block instead of an array literal.
2	Create the RectCoord object.
3	Create the `PolarCoord` object.
4	Use `setCoordinate` to assign the `RectCoord` object to the `PolarCoord`.
5	Use EGraph.setCoordinate(coord) to add the `Coordinate` 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.
