Aspose.Slides for PHP via Java now supports specifying the size of the hole in a doughnut chart. In this topic, we will see with example how to specify the size of the hole in a doughnut chart.

In order to specify the size of the hole in a doughnut chart, please follow the steps below:

1. Instantiate Presentation object.
2. Add doughnut chart on the slide.
3. Specify the size of the hole in a doughnut chart.
4. Write presentation to disk.

In the example given below, we have set the size of the hole in a doughnut chart.

  # Create an instance of Presentation class
  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Doughnut, 50, 50, 400, 400);
    $chart->getChartData()->getSeriesGroups()->get_Item(0)->setDoughnutHoleSize(90);
    # Write presentation to disk
    $pres->save("DoughnutHoleSize_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }
