Animated Charts

Aspose.Slides for Android via Java supports animating the chart elements. Series, Categories, Series Elements, Categories Elements can be animated with ISequence.addEffect method and two enums EffectChartMajorGroupingType and EffectChartMinorGroupingType.

Chart Series Animation

If you want to animate a chart series, write the code according to the steps listed below:

Load a presentation.
Get reference of the chart object.
Animate the series.
Write the presentation file to disk.

In the example given below, we animated chart series.

// Instantiate Presentation class that represents a presentation file
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    // Get reference of the chart object
    ISlide slide = pres.getSlides().get_Item(0);
    IShapeCollection shapes = slide.getShapes();
    IChart chart = (IChart) shapes.get_Item(0);

    // Animate the series
    slide.getTimeline().getMainSequence().addEffect(chart, EffectType.Fade, EffectSubtype.None,
            EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 0,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 1,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 2,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 3,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // Write the modified presentation to disk
    pres.save("AnimatingSeries_out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Chart Category Animation

If you want to animate a chart series, write the code according to the steps listed below:

Load a presentation.
Get reference of the chart object.
Animate the Category.
Write the presentation file to disk.

In the example given below, we animated chart category.

// Instantiate Presentation class that represents a presentation file
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    ISlide slide = pres.getSlides().get_Item(0);
    IShapeCollection shapes = slide.getShapes();
    IChart chart = (IChart) shapes.get_Item(0);

    slide.getTimeline().getMainSequence().addEffect(chart, EffectType.Fade, EffectSubtype.None,
            EffectTriggerType.AfterPrevious);

    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.ByCategory, 0, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    
    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart, 
            EffectChartMajorGroupingType.ByCategory, 1, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    
    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart, 
            EffectChartMajorGroupingType.ByCategory, 2, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    
    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart, 
            EffectChartMajorGroupingType.ByCategory, 3, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    pres.save("Sample_Animation_C.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Animation in Series Element

If you want to animate series elements, write the code according to the steps listed below:

Load a presentation.
Get reference of the chart object.
Animate series elements.
Write the presentation file to disk.

In the example given below, we have animated series' elements.

// Instantiate Presentation class that represents a presentation file
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    // Get reference of the chart object
    ISlide slide = pres.getSlides().get_Item(0);
    IShapeCollection shapes = slide.getShapes();
    IChart chart = (IChart) shapes.get_Item(0);

    // Animate series elements
    slide.getTimeline().getMainSequence().addEffect(chart, EffectType.Fade, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            0, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            0, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            0, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            0, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            1, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            1, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            1, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            1, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            2, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            2, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            2, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // Write the presentation file to disk 
    pres.save("AnimatingSeriesElements_out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Animation in Category Element

// Instantiate Presentation class that represents a presentation file
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    // Get reference of the chart object
    ISlide slide = pres.getSlides().get_Item(0);
    IShapeCollection shapes = slide.getShapes();
    IChart chart = (IChart) shapes.get_Item(0);

    // Animate categories' elements
    slide.getTimeline().getMainSequence().addEffect(chart, EffectType.Fade, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInCategory,
