Flash製グラフ作成「amcharts」
最近グラフを作成するためのツールを探したら「amcharts」がよさそう！
- 広告が小さい（左上にURL）
- PHPで簡単に作成するためのクラスを公開されてる方がいた
クラスが公開されていたサイトはこちら
http://neoinspire.net/archives/59
で、円グラフ以外も自分なりに使えるようにしてみた。
（公開されてるやつを元に作っちゃってるんで問題があればご一報を。）
サンプルとクラス

結果
こんなふうになるよーー。

以下フォルダ構成
ダウンロードしたライブラリ以下にデータフォルダを作成し、
グラフのデータファイルとセッティングファイルを作るようにします。
sampleは以下のような感じでふ
graphsample ├ amcolumn *1 │ └ data │ ├ amcolumn_data.xml │ └ amcolumn_settings.xml ├ amline *2 │ └ data │ ├ amline_data.xml │ └ amline_settings.xml ├ ampie *3 │ └ data │ ├ ampie_data.xml │ └ ampie_settings.xml ├ amxy *4 │ └ data_1 │ ├ amxy_data.xml │ └ amxy_settings.xml └ Class.CreateGraph.php
