Second Plot Options for Pie of Pie and Bar of Pie Chart

Aspose.Slides for PHP via Java now supports second plot options for Pie of Pie or Bar of Pie chart. In this topic, we will show you how to specify those options using Aspose.Slides. To specify the properties, do this:

  1. Instantiate Presentation class object.
  2. Add chart on the slide.
  3. Specify the second plot options of chart.
  4. Write presentation to disk.

In the example given below, we have set different properties of Pie of Pie chart.

  # Create an instance of Presentation class
  $pres = new Presentation();
  try {
    # Add chart on slide
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::PieOfPie, 50, 50, 500, 400);
    # Set different properties
    $chart->getChartData()->getSeries()->get_Item(0)->getLabels()->getDefaultDataLabelFormat()->setShowValue(true);
    $chart->getChartData()->getSeries()->get_Item(0)->getParentSeriesGroup()->setSecondPieSize(149);
    $chart->getChartData()->getSeries()->get_Item(0)->getParentSeriesGroup()->setPieSplitBy(PieSplitType::ByPercentage);
    $chart->getChartData()->getSeries()->get_Item(0)->getParentSeriesGroup()->setPieSplitPosition(53);
    # Write presentation to disk
    $pres->save("SecondPlotOptionsforCharts_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Automatic Pie Chart Slice Colors

Aspose.Slides for PHP via Java provides a simple API for setting automatic pie chart slide colors. The sample code applies setting the above said properties.

  1. Create an instance of the Presentation class.
  2. Access first slide.
  3. Add chart with default data.
  4. Set chart Title.
  5. Set first series to Show Values.
  6. Set the index of chart data sheet.
  7. Getting the chart data worksheet.
  8. Delete default generated series and categories.
  9. Add new categories.
  10. Add new series.

Write the modified presentation to a PPTX file.

  # Create an instance of Presentation class
  $pres = new Presentation();
  try {
    # Add chart with default data
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Pie, 100, 100, 400, 400);
    # Setting chart Title
    $chart->getChartTitle()->addTextFrameForOverriding("Sample Title");
    $chart->getChartTitle()->getTextFrameForOverriding()->getTextFrameFormat()->setCenterText(NullableBool::True);
    $chart->getChartTitle()->setHeight(20);
    $chart->setTitle(true);
    # Set first series to Show Values
    $chart->getChartData()->getSeries()->get_Item(0)->getLabels()->getDefaultDataLabelFormat()->setShowValue(true);
    # Setting the index of chart data sheet
    $defaultWorksheetIndex = 0;
    # Getting the chart data worksheet
    $fact = $chart->getChartData()->getChartDataWorkbook();
    # Delete default generated series and categories
    $chart->getChartData()->getSeries()->clear();
    $chart->getChartData()->getCategories()->clear();
    # Adding new categories
    $chart->getChartData()->getCategories()->add($fact->getCell(0, 1, 0, "First Qtr"));
    $chart->getChartData()->getCategories()->add($fact->getCell(0, 2, 0, "2nd Qtr"));
    $chart->getChartData()->getCategories()->add($fact->getCell(0, 3, 0, "3rd Qtr"));
    # Adding new series
    $series = $chart->getChartData()->getSeries()->add($fact->getCell(0, 0, 1, "Series 1"), $chart->getType());
    # Now populating series data
    $series->getDataPoints()->addDataPointForPieSeries($fact->getCell($defaultWorksheetIndex, 1, 1, 20));
    $series->getDataPoints()->addDataPointForPieSeries($fact->getCell($defaultWorksheetIndex, 2, 1, 50));
    $series->getDataPoints()->addDataPointForPieSeries($fact->getCell($defaultWorksheetIndex, 3, 1, 30));
    $series->getParentSeriesGroup()->setColorVaried(true);
    $pres->save("Pie.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }
