PHPExcel Chart 直接下载时无法使用

Question

这是我的代码...它与示例代码相同...除了最后，我将其更改为直接从浏览器下载而不是在服务器上创建文件。

当我下载 excel 时，我只看到了这些（没有图表）：

<?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');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');

我是不是漏掉了什么？

Answer 1

哇我忘记了一个关键部分。希望这对其他错过它的人有所帮助。

$objWriter->setIncludeCharts(TRUE);

所以它应该是这样的：

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->setIncludeCharts(TRUE);
$objWriter->save('php://output');
