PHP MySQL Google Chart JSON-完全な例

MySQLテーブルデータをデータソースとして使用してGoogle Chartを生成する良い例を見つけるために、多くのことを検索しました。数日間検索したところ、PHPとMySQLの組み合わせを使用してGoogleグラフ（円、棒、列、表）を生成するためのサンプルがほとんどないことがわかりました。私はついに1つの例を機能させることができました。

以前、StackOverflowから多くの支援を受けていたので、今回はいくつかを返します。

2つの例を示します。 1つはAjaxを使用し、もう1つは使用しません。今日は、非Ajaxの例のみを示します。

使用法：

要件：PHP、ApacheおよびMySQL 
 
インストール：
 
 --- phpMyAdminを使用してデータベースを作成し、「chart」という名前を付けます
 --- phpMyAdminを使用してテーブルを作成し、「googlechart」という名前を付けて、
に2つの列を使用したため、2つの列のみがあることを確認します。ただし、
は必要に応じて2つ以上の列を使用できますが、そのために
コードを少し変更する必要があります
 ---次のように列名を指定します： "weekly_task "and" percentage "
 ---テーブルにデータを挿入します
 ---パーセンテージ列には数字のみを使用します
 
 ----- ---------------------------- 
サンプルデータ：テーブル（googlechart）
 ----- ---------------------------- 
 
 weekly_taskパーセンテージ

ローカルまたはサーバー上でこのエラーが発生する場合があります。

syntax error var data = new google.visualization.DataTable(<?=$jsonTable?>);

これは、彼らの環境が短いタグをサポートしていないことを意味し、解決策は代わりにこれを使用することです：

<?php echo $jsonTable; ?>

そして、すべて正常に動作するはずです！

このエラーが発生する場合があります（PHP-MySQLi-JSON-Google Chart例の実装中にエラーが発生しました）：

DataTableまたはDataViewではなく、間違ったタイプのデータでdraw（）メソッドを呼び出しました。

解決策は次のとおりです：jsapiを置き換え、loader.jsを次のように使用するだけです：

google.charts.load('current', {packages: ['corechart']}) and 
google.charts.setOnLoadCallback

-リリースノートによると-> jsapiローダー経由で利用可能なGoogle Chartのバージョンは、一貫して更新されなくなりました。今後は新しいgstaticローダーを使用してください。
