php - Chart not rendered properly -

-

i have small table

my table

and want create type_donutchart phpexcel library. took example code examples/33chartcreate-pie.php file , adapted accordingly:

$dataserieslabels2 = array(     //new phpexcel_chart_dataseriesvalues('string', 'summen!$a$1', null, 1), ); $xaxistickvalues2 = array(     new phpexcel_chart_dataseriesvalues('string', 'summen!$b$1:$c$1', null, 2), ); $dataseriesvalues2 = array(     new phpexcel_chart_dataseriesvalues('number', 'summen!$b$2:$c$2', null, 2), );

the file served script, when try open it, error message occurs:

we found problem content in "myfile.xlsx". want try recover as can? if trust source of workbook, click yes.

when click yes , activate editing on document, following message this:

excel has finished check , repair of file. parts of file have been repaired or discarded.

removed part: part /xl/drawings/drawing4.xml. (drawing form)

what's wrong in code? have modify?

notes:

  • as can see, i'm using dataset in example. there's data in range a1:c2 (see screenshot above).
  • the worksheets name summen, double checked, problem not typo of sheet.
  • it's been asked in comments, have tried removing comment dataserieslabels2 entry.

my example

$objphpexcel = new phpexcel(); $objworksheet = $objphpexcel->getactivesheet(); $objworksheet->fromarray(     array(         array('whatever', 'cat1', 'cat2'),         array(77,         247,    128),     ) ); $objworksheet->settitle('summen');  $dataserieslabels1 = array( //    new phpexcel_chart_dataseriesvalues('string', 'summen!$a$1', null, 1), );  $xaxistickvalues1 = array(     new phpexcel_chart_dataseriesvalues('string', 'summen!$b$1:$c$1', null, 2), );  $dataseriesvalues1 = array(     new phpexcel_chart_dataseriesvalues('number', 'summen!$b$2:$c$2', null, 2), );  $series1 = new phpexcel_chart_dataseries(     phpexcel_chart_dataseries::type_donutchart, // plottype     null,                           // plotgrouping     range(0, count($dataseriesvalues1)-1),      // plotorder     $dataserieslabels1,             // plotlabel     $xaxistickvalues1,              // plotcategory     $dataseriesvalues1              // plotvalues );  $layout1 = new phpexcel_chart_layout(); $layout1->setshowval(true); $layout1->setshowpercent(true);  $plotarea1 = new phpexcel_chart_plotarea($layout1, array($series1)); $legend1 = new phpexcel_chart_legend(phpexcel_chart_legend::position_right, null, false); $title1 = new phpexcel_chart_title('test pie chart');   $chart1 = new phpexcel_chart(     'chart1',       // name     $title1,        // title     $legend1,       // legend     $plotarea1,     // plotarea     true,       // plotvisibleonly     0,          // displayblanksas     null,       // xaxislabel     null        // yaxislabel       - pie charts don't have y-axis );  //  set position chart should appear in worksheet $chart1->settopleftposition('a7'); $chart1->setbottomrightposition('h20');  //  add chart worksheet $objworksheet->addchart($chart1);   $objwriter = phpexcel_iofactory::createwriter($objphpexcel, 'excel2007'); $objwriter->setincludecharts(true); $objwriter->save(str_replace('.php', '.xlsx', __file__));

generates correctly without errors
