Question

require_once('PHPExcel-1.7.7/Classes/PHPExcel.php');

$inputFileName = 'RN Tracker.xlsx';

$inputFileType = PHPExcel_IOFactory::identify($inputFileName);

 $objReader = PHPExcel_IOFactory::createReader($inputFileType);

if i try following

$objReader->setIncludeCharts(TRUE);

during load i get following error message:

Warning: PHPExcel_Reader_Excel2007::load(): Node no longer exists in /users/pravkum4/html/tracker/PHPExcel-1.7.7/Classes/PHPExcel/Reader/Excel2007.php on line 1518

Notice: Trying to get property of non-object in /users/pravkum4/html/tracker/PHPExcel-1.7.7/Classes/PHPExcel/Reader/Excel2007.php on line 1519

Fatal error: Call to a member function children() on a non-object in /users/pravkum4/html/tracker/PHPExcel-1.7.7/Classes/PHPExcel/Reader/Excel2007.php on line 1519

What mistake i am doing here?
Should i include some additional class for chart?

Does chart option is included by default in load method of reader? chart count gives 0. :((
Sometimes gives correct chart count but rendering doesn’t work.

One more thing, what is this code? not working for me. Sometimes i get jpgraph_pie.php missing.

PHPExcel_Settings::setChartRenderer(
    PHPExcel_Settings::CHART_RENDERER_JPGRAPH,
    dirname(__FILE__).'/../../libraries/Charts/jpgraph3.5.0b1/src'
);

Please provide a tutorial for chart rendering. Thank you so much in Advance.

I have yet to see this issue raised at the PHPExcel sites on either CodePlex or on Github… and to resolve it you’ll need to upload a sample file that demonstrates the problem so that we can identify what node no longer exists in the Excel data
