PHPExcel Pie graph error

Question

I'm trying to make a pie chart in PHP Excel, but I'm not getting it to work. I've made a working Bar graph, and that works flawlessly. But this example of PHPExcel doesn't work:

<?php

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),
    )
);

// Save Excel 2007 file

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->setIncludeCharts(TRUE);
$objWriter->save(str_replace('.php', '.xlsx', __FILE__));
echo date('H:i:s') , " File written to " , str_replace('.php', '.xlsx', pathinfo(__FILE__, PATHINFO_BASENAME)) , EOL;


// Echo memory peak usage
echo date('H:i:s') , " Peak memory usage: " , (memory_get_peak_usage(true) / 1024 / 1024) , " MB" , EOL;

// Echo done
echo date('H:i:s') , " Done writing file" , EOL;
echo 'File has been created in ' , getcwd() , EOL;

This is my PHPExcel pie example. It exports a excel file but it gives an error that the graph isn't properly rendered and it can be opened if Excel deletes the graph.

I know this is an old question, but for newcomers.

This seems an issue and it isn't fixed in the current version (1.8.1). Basically,

You should not use PHPExcel_Chart_DataSeries::GROUPING_STANDARD for pie charts
