Class usage and Overview

The canvas for use with PiePlots. You add pie plots by calling the Add() method.

You can add several PiePlots by adjusting their size and positioning each PiePlot so it doesn't overlap eachother.

Class Methods

function Add($aObj)

Add object to the pie graph

Argument Default Description

$aObj Object to add

Argument	Default	Description
$aObj		Object to add

Description

Add a pieplots or text object to the pie graph. You can specify either a single object or an array. If you specify an array all object in the array must be of the same type.

Example

$piegraph = new PieGraph(300,400);
$pieplot = new PiePlot($ydata);
$piegraph->Add($pieplot);

function PieGraph($width,$height,$cachedName,$timeout,$inline)

//---------------// CONSTRUCTOR

Argument Default Description

$width 300 Width of graph

$height 200 Height of graph

$cachedName "" Cache file name

$timeout 0 Cache timeout in s

$inline 1 Should the image be inline.

Argument	Default	Description
$width	300	Width of graph
$height	200	Height of graph
$cachedName	""	Cache file name

function SetAntiAliasing($aFlg)

Enable/disable anti-alias for Pie Graphs

Argument Default Description

$aFlg true true=enable anti-aliasing

Argument	Default	Description
$aFlg	true	true=enable anti-aliasing

Description

Enable/disable anti-alias for Pie Graphs. This makes for much nicer looking PieGraphs. Please note that enabling anti-alias imposes some restrictions:

Enabling anti-alias will severely impact performance. As a rule of thumb you can expect drawing to take 5-8 times longer !
You can't use background images or gradient backgrounds together with anti-alias

Example

$piegraph->SetAntiAlias();

function SetColor($c)

Set the background color. Synonym to SetMarginColor()

Argument Default Description

$c Color

Argument	Default	Description
$c		Color

Description

Set the background color. Synonym to SetMarginColor()
