Set Chart Series Overlap

With the IChartSeriesOverlap property, you can specify how much bars and columns should overlap on a 2D chart (range: -100 to 100). This property applies to all series of the parent series group: this is a projection of the appropriate group property. Therefore, this property is read-only.

Use the ParentSeriesGroup.Overlap read/write property to set your preferred value for Overlap.

  1. Create an instance of the Presentation class.
  2. Add a clustered column chart on a slide.
  3. Access the first chart series.
  4. Access the chart series' ParentSeriesGroup and set your preferred overlap value for the series.
  5. Write the modified presentation to a PPTX file.

This PHP code shows you how to set the overlap for a chart series:

  $pres = new Presentation();
  try {
    # Adds chart
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::ClusteredColumn, 50, 50, 600, 400, true);
    $series = $chart->getChartData()->getSeries();
    if (java_values($series->get_Item(0)->getOverlap()) == 0) {
      # Sets series overlap
      $series->get_Item(0)->getParentSeriesGroup()->setOverlap(-30);
    }
    # Writes the presentation file to disk
    $pres->save("SetChartSeriesOverlap_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Change Series Color

Aspose.Slides for PHP via Java allows you to change a series' color this way:

  1. Create an instance of the Presentation class.
  2. Add chart on the slide.
  3. Access the series whose color you want to change.
  4. Set your preferred fill type and fill color.
  5. Save the modified presentation.

This PHP code shows you how to change a series' color:

  $pres = new Presentation("test.pptx");
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Pie, 50, 50, 600, 400);
    $point = $chart->getChartData()->getSeries()->get_Item(0)->getDataPoints()->get_Item(1);
    $point->setExplosion(30);
    $point->getFormat()->getFill()->setFillType(FillType::Solid);
    $point->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->BLUE);
    $pres->save("output.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Change Series Category’s Color

Aspose.Slides for PHP via Java allows you to change a series category’s color this way:

  1. Create an instance of the Presentation class.
  2. Add chart on the slide.
  3. Access the series category whose color you want to change.
  4. Set your preferred fill type and fill color.
  5. Save the modified presentation.

This code shows you how to change a series category’s color:

  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::ClusteredColumn, 50, 50, 600, 400);
    $point = $chart->getChartData()->getSeries()->get_Item(0)->getDataPoints()->get_Item(0);
    $point->getFormat()->getFill()->setFillType(FillType::Solid);
    $point->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->BLUE);
    $pres->save("output.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Change Series' Name

By default, the legend names for a chart are the contents of cells above each column or row of data.

In our example (sample image),

  • the columns are Series 1, Series 2, and Series 3;
  • the rows are Category 1, Category 2, Category 3, and Category 4.

Aspose.Slides for PHP via Java allows you to update or change a series name in its chart data and legend.

This PHP code shows you how to change a series' name in its chart data ChartDataWorkbook:

  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Column3D, 50, 50, 600, 400, true);
    $seriesCell = $chart->getChartData()->getChartDataWorkbook()->getCell(0, 0, 1);
    $seriesCell->setValue("New name");
    $pres->save("pres.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

This PHP code shows you how to change a series name in its legend throughSeries:

  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Column3D, 50, 50, 600, 400, true);
    $series = $chart->getChartData()->getSeries()->get_Item(0);
    $name = $series->getName();
    $name->getAsCells()->get_Item(0)->setValue("New name");
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Chart Series Fill Color

Aspose.Slides for PHP via Java allows you to set the automatic fill color for chart series inside a plot area this way:

  1. Create an instance of the Presentation class.
  2. Obtain a slide’s reference by its index.
  3. Add a chart with default data based on your preferred type (in the example below, we used ChartType::ClusteredColumn).
  4. Access the chart series and set the fill color to Automatic.
  5. Save the presentation to a PPTX file.

This PHP code shows you how to set the automatic fill color for a chart series:

  $pres = new Presentation();
  try {
    # Creates a clustered column chart
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::ClusteredColumn, 100, 50, 600, 400);
    # Sets series fill format to automatic
    for($i = 0; $i < java_values($chart->getChartData()->getSeries()->size()) ; $i++) {
      $chart->getChartData()->getSeries()->get_Item($i)->getAutomaticSeriesColor();
    }
    # Writes the presentation file to disk
    $pres->save("AutoFillSeries_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Chart Series Invert Fill Colors

Aspose.Slides allows you to set the invert fill color for chart series inside a plot area this way:

  1. Create an instance of the Presentation class.
  2. Obtain a slide’s reference by its index.
  3. Add a chart with default data based on your preferred type (in the example below, we used ChartType::ClusteredColumn).
  4. Access the chart series and set the fill color to invert.
  5. Save the presentation to a PPTX file.

This PHP code demonstrates the operation:

  $inverColor = java("java.awt.Color")->RED;
  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::ClusteredColumn, 100, 100, 400, 300);
    $workBook = $chart->getChartData()->getChartDataWorkbook();
    $chart->getChartData()->getSeries()->clear();
    $chart->getChartData()->getCategories()->clear();
    # Adds new series and categories
    $chart->getChartData()->getSeries()->add($workBook->getCell(0, 0, 1, "Series 1"), $chart->getType());
    $chart->getChartData()->getCategories()->add($workBook->getCell(0, 1, 0, "Category 1"));
    $chart->getChartData()->getCategories()->add($workBook->getCell(0, 2, 0, "Category 2"));
    $chart->getChartData()->getCategories()->add($workBook->getCell(0, 3, 0, "Category 3"));
    # Takes the first chart series and populates its series data.
    $series = $chart->getChartData()->getSeries()->get_Item(0);
    $series->getDataPoints()->addDataPointForBarSeries($workBook->getCell(0, 1, 1, -20));
    $series->getDataPoints()->addDataPointForBarSeries($workBook->getCell(0, 2, 1, 50));
    $series->getDataPoints()->addDataPointForBarSeries($workBook->getCell(0, 3, 1, -30));
    $seriesColor = $series->getAutomaticSeriesColor();
    $series->setInvertIfNegative(true);
    $series->getFormat()->getFill()->setFillType(FillType::Solid);
    $series->getFormat()->getFill()->getSolidFillColor()->setColor($seriesColor);
    $series->getInvertedSolidFillColor()->setColor($inverColor);
    $pres->save("SetInvertFillColorChart_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Series to Invert When Value is Negative

Aspose.Slides allows you to set inverts through theIChartDataPoint.InvertIfNegative and ChartDataPoint.InvertIfNegative properties. When an invert is set using the properties, the data point inverts its colors when it gets a negative value.

This PHP code demonstrates the operation:

  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::ClusteredColumn, 50, 50, 600, 400, true);
    $series = $chart->getChartData()->getSeries();
    $chart->getChartData()->getSeries()->clear();
    $chartSeries = $series->add($chart->getChartData()->getChartDataWorkbook()->getCell(0, "B1"), $chart->getType());
    $chartSeries->getDataPoints()->addDataPointForBarSeries($chart->getChartData()->getChartDataWorkbook()->getCell(0, "B2", -5));
    $chartSeries->getDataPoints()->addDataPointForBarSeries($chart->getChartData()->getChartDataWorkbook()->getCell(0, "B3", 3));
    $chartSeries->getDataPoints()->addDataPointForBarSeries($chart->getChartData()->getChartDataWorkbook()->getCell(0, "B4", -2));
    $chartSeries->getDataPoints()->addDataPointForBarSeries($chart->getChartData()->getChartDataWorkbook()->getCell(0, "B5", 1));
    $chartSeries->setInvertIfNegative(false);
    $chartSeries->getDataPoints()->get_Item(2)->setInvertIfNegative(true);
    $pres->save("out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Clear Specific Data Points' Data

Aspose.Slides for PHP via Java allows you to clear the DataPoints data for a specific chart series this way:

  1. Create an instance of the Presentation class.
  2. Obtain the reference of a slide through its index.
  3. Obtain the reference of a chart through its index.
  4. Iterate through all the chart DataPoints and set XValue and YValue to null.
  5. Clear allDataPoints for specific chart series.
  6. Write the modified presentation to a PPTX file.

This PHP code demonstrates the operation:

  $pres = new Presentation("TestChart.pptx");
  try {
    $sl = $pres->getSlides()->get_Item(0);
    $chart = $sl->getShapes()->get_Item(0);
    foreach($chart->getChartData()->getSeries()->get_Item(0)->getDataPoints() as $dataPoint) {
      $dataPoint->getXValue()->getAsCell()->setValue(null);
      $dataPoint->getYValue()->getAsCell()->setValue(null);
    }
    $chart->getChartData()->getSeries()->get_Item(0)->getDataPoints()->clear();
    $pres->save("ClearSpecificChartSeriesDataPointsData.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Series Gap Width

Aspose.Slides for PHP via Java allows you to set a series' Gap Width through the GapWidth property this way:

  1. Create an instance of the Presentation class.
  2. Access first slide.
  3. Add chart with default data.
  4. Access any chart series.
  5. Set the GapWidth property.
  6. Write the modified presentation to a PPTX file.

This code shows you how to set a series' Gap Width:

  # Creates empty presentation
  $pres = new Presentation();
  try {
    # Accesses the presentation's first slide
    $slide = $pres->getSlides()->get_Item(0);
    # Adds a chart with default data
    $chart = $slide->getShapes()->addChart(ChartType::StackedColumn, 0, 0, 500, 500);
    # Sets the index of the chart data sheet
    $defaultWorksheetIndex = 0;
    # Gets the chart data worksheet
    $fact = $chart->getChartData()->getChartDataWorkbook();
    # Adds series
    $chart->getChartData()->getSeries()->add($fact->getCell($defaultWorksheetIndex, 0, 1, "Series 1"), $chart->getType());
    $chart->getChartData()->getSeries()->add($fact->getCell($defaultWorksheetIndex, 0, 2, "Series 2"), $chart->getType());
    # Adds Categories
    $chart->getChartData()->getCategories()->add($fact->getCell($defaultWorksheetIndex, 1, 0, "Caetegoty 1"));
    $chart->getChartData()->getCategories()->add($fact->getCell($defaultWorksheetIndex, 2, 0, "Caetegoty 2"));
    $chart->getChartData()->getCategories()->add($fact->getCell($defaultWorksheetIndex, 3, 0, "Caetegoty 3"));
    # Takes the second chart series
    $series = $chart->getChartData()->getSeries()->get_Item(1);
    # Populates the series data
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 1, 1, 20));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 2, 1, 50));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 3, 1, 30));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 1, 2, 30));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 2, 2, 10));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 3, 2, 60));
    # Sets GapWidth value
    $series->getParentSeriesGroup()->setGapWidth(50);
    # Saves presentation to disk
    $pres->save("GapWidth_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }
