动画图表

Aspose.Slides for .NET支持动画图表元素。系列、类别、系列元素、类别元素可以通过ISequence.AddEffect方法和两个枚举EffectChartMajorGroupingType和EffectChartMinorGroupingType进行动画处理。

图表系列动画

如果您想为图表系列添加动画，请根据以下步骤编写代码：

  1. 加载演示文稿。
  2. 获取图表对象的引用。
  3. 为系列添加动画。
  4. 将演示文稿文件写入磁盘。

在下面给出的示例中，我们对图表系列进行了动画处理。

// 实例化Presentation类，表示演示文稿文件 
using (Presentation presentation = new Presentation("ExistingChart.pptx"))
{
    // 获取图表对象的引用
    var slide = presentation.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;

    // 为系列添加动画
    slide.Timeline.MainSequence.AddEffect(chart, EffectType.Fade, EffectSubtype.None,
    EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 0,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 1,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 2,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 3,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // 将修改后的演示文稿写入磁盘 
    presentation.Save("AnimatingSeries_out.pptx", SaveFormat.Pptx);
}

图表类别动画

如果您想为图表类别添加动画，请根据以下步骤编写代码：

  1. 加载演示文稿。
  2. 获取图表对象的引用。
  3. 为类别添加动画。
  4. 将演示文稿文件写入磁盘。

在下面给出的示例中，我们对图表类别进行了动画处理。

using (Presentation presentation = new Presentation("ExistingChart.pptx"))
{
    // 获取图表对象的引用
    var slide = presentation.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;

    // 为类别元素添加动画
    slide.Timeline.MainSequence.AddEffect(chart, EffectType.Fade, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // 将演示文稿文件写入磁盘
    presentation.Save("AnimatingCategoriesElements_out.pptx", SaveFormat.Pptx);
}

系列元素中的动画

如果您想为系列元素添加动画，请根据以下步骤编写代码：

  1. 加载演示文稿。
  2. 获取图表对象的引用。
  3. 为系列元素添加动画。
  4. 将演示文稿文件写入磁盘。

在下面给出的示例中，我们对系列元素进行了动画处理。

// 加载演示文稿
using (Presentation presentation = new Presentation("ExistingChart.pptx"))
{
    // 获取图表对象的引用
    var slide = presentation.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;

    // 为系列元素添加动画
    slide.Timeline.MainSequence.AddEffect(chart, EffectType.Fade, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 0, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 0, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
