PHPExcel饼图错误

Question

我正在尝试在 PHP Excel 中制作饼图，但无法正常工作。我制作了一个工作条形图，并且可以完美运行。但是这个 PHPExcel 的例子不起作用：

<?php



/** PHPExcel */
require_once dirname(__FILE__) . '/../Classes/PHPExcel.php';


$objPHPExcel = new PHPExcel();
$objWorksheet = $objPHPExcel->getActiveSheet();
$objWorksheet->fromArray(
    array(
        array('',   2010,   2011,   2012),
        array('Q1',   12,   15,     21),
        array('Q2',   56,   73,     86),
        array('Q3',   52,   61,     69),
        array('Q4',   30,   32,     0),
    )
);

// Echo done

echo 'File has been created in ' , getcwd() , EOL;

这是我的 PHPExcel 饼图示例。它导出一个 excel 文件，但它给出了一个错误，即图形未正确呈现，如果 Excel 删除图形，它可以打开。

我知道这是一个老问题，但对于新手来说。

这似乎是 issue 并且在当前版本 (1.8.1) 中未修复。基本上，

You should not use PHPExcel_Chart_DataSeries::GROUPING_STANDARD for pie charts
