PHPExcel饼图系列选项在主轴上为25％

Question

I was able to create 2 pie charts programmatically (im using PHP), using the PHPExcel library (no need to list the code since it's too large) but i can not find a way to increase the distance between the pie's pieces like in the picture below. Basically, im trying to programmatically increase the Series Options on primary axis by 25%.

When you init new PHPExcel_Chart_DataSeries object, you can specified $plotStyle=true.

public function __construct($plotType = null, $plotGrouping = null, $plotOrder = array(), $plotLabel = array(), $plotCategory = array(), $plotValues = array(), $plotDirection = null, $smoothLine = null, $plotStyle = null)

For PHPExcel\Examples\33chartcreate-pie.php:88 it will be something like there:

$series1 = new PHPExcel_Chart_DataSeries(
    PHPExcel_Chart_DataSeries::TYPE_PIECHART,
    NULL,                                                   
    range(0, count($dataSeriesValues1)-1),                  
    $dataSeriesLabels1,                                     
    $xAxisTickValues1,                                      
    $dataSeriesValues1,                                     
    null,
    null,
    true
);
