Introduction

Aspose.Slides for 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. The chart in the example file has three series, so one effect is added for each index from 0 to 2. Aspose.Slides does not check the index against the chart data, and an effect added for a series that does not exist is written to the file but animates nothing—keep the index below the number of series in your own chart.

import com.aspose.slides.*;

// 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);

    // 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 category, 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.

import com.aspose.slides.*;

// 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 a 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.

import com.aspose.slides.*;

// 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, 2, 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();
}

FAQ

Are different effect types (e.g., entrance, emphasis, exit) supported for charts like for regular shapes?

Yes. A chart is treated as a shape, so it supports the standard animation effect types, including entrance, emphasis, and exit, with full control via the slide’s timeline and animation sequences.

Can I combine chart animation with slide transitions?

Yes. Transitions apply to the slide, while animation effects apply to objects on the slide. You can use both together in the same presentation and control them independently.

Are chart animations preserved when saving to PPTX?

Yes. When you save to PPTX, all animation effects and their ordering are preserved because they are part of the presentation’s native animation model.

Can I read existing chart animations from a presentation and modify them?

Yes. The API provides access to the slide timeline, sequences, and effects, allowing you to inspect existing chart animations and adjust them without recreating everything from scratch.

Can I produce a video that includes chart animations using Aspose.Slides?

Yes. You can export a presentation to video while preserving animations, configuring timings and other export settings so the resulting clip reflects the animated playback.
