    chart.getChartData().getSeriesGroups().get_Item(0).getHiLowLinesFormat().getLine().getFillFormat().setFillType(FillType.Solid);

    for(IChartSeries ser : chart.getChartData().getSeries())
    {
        ser.getFormat().getLine().getFillFormat().setFillType(FillType.NoFill);
    }

    pres.save("output.pptx", SaveFormat.Pptx);
} finally {
    pres.dispose();
}

} finally {
    pres.dispose();
}

try {
    IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.OpenHighLowClose, 50, 50, 600, 400, true);

    chart.getChartData().getSeriesGroups().get_Item(0).getHiLowLinesFormat().getLine().getFillFormat().setFillType(FillType.Solid);
    chart.getChartData().getSeriesGroups().get_Item(0).getHiLowLinesFormat().getLine().getFillFormat().getSolidFillColor().setColor(Color.RED);

    pres.save("output.pptx", SaveFormat.Pptx);
} finally {
    pres.dispose();
}

    options.setImageTransparentColor(Color.WHITE);
    pres.save("pres.pdf", SaveFormat.Pdf, options);
} finally {
    pres.dispose();
}

getInvertIfNegative and setInvertIfNegative methods have been added to IChartDataPoint

getInvertIfNegative and setInvertIfNegative methods have been added to IChartDataPoint.

Specifies the data point shall invert its colors if the value is negative.

Presentation pres = new Presentation();
try {
    IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.ClusteredColumn, 50, 50, 600, 400, true);
    IChartSeriesCollection series = chart.getChartData().getSeries();
    chart.getChartData().getSeries().clear();

    series.add(chart.getChartData().getChartDataWorkbook().getCell(0, "B1"), chart.getType());

    series.get_Item(0).getDataPoints().addDataPointForBarSeries(chart.getChartData().getChartDataWorkbook().getCell(0, "B3",3));
    series.get_Item(0).getDataPoints().addDataPointForBarSeries(chart.getChartData().getChartDataWorkbook().getCell(0, "B4",-2));
    series.get_Item(0).getDataPoints().addDataPointForBarSeries(chart.getChartData().getChartDataWorkbook().getCell(0, "B5",1));

    series.get_Item(0).setInvertIfNegative(false);
    series.get_Item(0).getInvertIfNegative()
    series.get_Item(0).getDataPoints().get_Item(2).setInvertIfNegative(true);

    pres.save("output.pptx", SaveFormat.Pptx);
} finally {
    pres.dispose();
}

hasRoundedCorners and setRoundedCorners methods have been added to IChart

hasRoundedCorners and setRoundedCorners methods have been added to IChart.

Specifies the chart area shall have rounded corners.

Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);
    IChart chart = slide.getShapes().addChart(ChartType.ClusteredColumn, 20, 100, 600, 400);
    chart.setRoundedCorners(true);
    presentation.save("output.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}

The implementation of method IChartData.setRange() has been changed.

Implementation of the method has been changed to avoid lost of series settings (series type, formatting and etc.). Only data points will be updated.

If a number of series in data range greater than a count of series in the chart data, then additional series with the same type as the last series in the current collection will be added to the end of the collection.

The LightStyle1Accent5 value has been added to TableStylePreset enum

LightStyle1Accent5 value has been added to TableStylePreset enum.

It represents “Light Style 1 - Accent 5” preset table style.

The code snippet below shows how to add a new Table with “Light Style 1 - Accent 5” style:

Presentation presentation = new Presentation();
try {
    ITable table = presentation.getSlides().get_Item(0).getShapes().addTable(50, 50, new double[] { 200, 200 }, new double[] { 50, 50, 50, 50 });
    table.setStylePreset(TableStylePreset.LightStyle1Accent5);

    presentation.save("presentation-out.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}

The obsolete HeaderFooterManager class has been deleted

Obsolete HeaderFooterManager class has been deleted.

Please use class PresentationHeaderFooterManager or one of the corresponding classes MasterSlideHeaderFooterManager, LayoutSlideHeaderFooterManager, SlideHeaderFooterManager instead.
