Question

我正在测试PHPExcel库示例中的 33chartcreate-column.php 示例。代码是：

<?php

/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

date_default_timezone_set('Europe/London');

我想要的是什么：

有没有办法像第二张图片一样旋转标签？（我的意思是在生成.xslx文件之前，通过php文件中允许前面代码的代码）。我使用的是PHPEXCEL 1.8.0版本

Answer 1

我发现PHPExcel库会自动旋转标签。如果你减少图表的宽度，它取决于图表的宽度。标签就像第二张图片一样。通过代码我不知道怎么做，但正如我所说，如果你减少图表宽度，标签在第二张图片中看起来像。并且还取决于每个标签的长度。

PHPExcel旋转柱形图标签
