在 PHP 中创建或更新 PowerPoint 演示文稿图表

本页内容简介

使用 Aspose.Slides for PHP via Java 在 PowerPoint 演示文稿中创建和自定义图表。通过实用的代码示例添加、格式化和编辑图表。

概述

本文提供了使用 Aspose.Slides 创建和自定义图表的综合指南。您将学习如何以编程方式向幻灯片添加图表、填充数据，并应用各种格式选项以满足特定的设计需求。文章中提供了详细的代码示例，展示了从初始化演示文稿和图表对象到配置系列、坐标轴和图例的每一步。通过本指南，您将深入了解如何在应用程序中集成动态图表生成，简化创建数据驱动演示文稿的过程。

创建图表

图表帮助人们快速可视化数据，并获得可能不易从表格或电子表格中直接看出的洞察。

为什么要创建图表？

使用图表，您可以：

• 在单个幻灯片上汇总、压缩或概括大量数据
• 展示数据中的模式和趋势
• 推断数据随时间或相对于特定计量单位的方向和动量
• 发现异常值、偏差、错误、无意义的数据等
• 传达或展示复杂数据

在 PowerPoint 中，您可以通过 Insert 功能创建图表，该功能提供了多种图表模板。使用 Aspose.Slides，您既可以创建常规图表（基于流行的图表类型），也可以创建自定义图表。

Note

要创建图表，使用 ChartType 类。该类中的字段对应不同的图表类型。

创建簇状柱形图

本节说明如何使用 Aspose.Slides 创建簇状柱形图。您将学习初始化演示文稿、添加图表以及自定义标题、数据、系列、类别和样式等元素。按照以下步骤查看如何生成标准的簇状柱形图：

1. 创建 Presentation 类的实例。
2. 使用索引获取幻灯片的引用。
3. 添加带有一些数据的图表，并指定 ChartType::ClusteredColumn 类型。
4. 为图表添加标题。
5. 访问图表的数据工作表。
6. 清除所有默认的系列和分类。
7. 添加新的系列和分类。
8. 为图表系列添加新的图表数据。
9. 为图表系列应用填充颜色。
10. 为图表系列添加标签。
11. 将修改后的演示文稿保存为 PPTX 文件。

  # 实例化表示 PPTX 文件的演示文稿类
  $pres = new Presentation();
  try {
    # 访问第一张幻灯片
    $sld = $pres->getSlides()->get_Item(0);
    # 添加一个带默认数据的图表
    $chart = $sld->getShapes()->addChart(ChartType::ClusteredColumn, 0, 0, 500, 500);
    # 设置图表标题
    $chart->getChartTitle()->addTextFrameForOverriding("Sample Title");
    $chart->getChartTitle()->getTextFrameForOverriding()->getTextFrameFormat()->setCenterText(NullableBool::True);
    $chart->getChartTitle()->setHeight(20);
    $chart->hasTitle();
    # 设置第一系列显示数值
    $chart->getChartData()->getSeries()->get_Item(0)->getLabels()->getDefaultDataLabelFormat()->setShowValue(true);
    # 设置图表数据表的索引
    $defaultWorksheetIndex = 0;
    # 获取图表数据工作表
    $fact = $chart->getChartData()->getChartDataWorkbook();
    # 删除默认生成的系列和类别
    $chart->getChartData()->getSeries()->clear();
    $chart->getChartData()->getCategories()->clear();
    $s = $chart->getChartData()->getSeries()->size();
    $s = $chart->getChartData()->getCategories()->size();
    # 添加新系列
    $chart->getChartData()->getSeries()->add($fact->getCell($defaultWorksheetIndex, 0, 1, "Series 1"), $chart->getType());
    $chart->getChartData()->getSeries()->add($fact->getCell($defaultWorksheetIndex, 0, 2, "Series 2"), $chart->getType());
    # 添加新类别
    $chart->getChartData()->getCategories()->add($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"));
    # 获取第一条图表系列
    $series = $chart->getChartData()->getSeries()->get_Item(0);
    # 现在填充系列数据
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 1, 1, 20));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 2, 1, 50));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 3, 1, 30));
    # 设置系列的填充颜色
    $series->getFormat()->getFill()->setFillType(FillType::Solid);
    $series->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
    # 获取第二条图表系列
    $series = $chart->getChartData()->getSeries()->get_Item(1);
    # 填充系列数据
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 1, 2, 30));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 2, 2, 10));
    $series->getDataPoints()->addDataPointForBarSeries($fact->getCell($defaultWorksheetIndex, 3, 2, 60));
    # 设置系列的填充颜色
    $series->getFormat()->getFill()->setFillType(FillType::Solid);
    $series->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->GREEN);
    # 为新系列的每个类别创建自定义标签
    # 设置第一个标签显示类别名称
    $lbl = $series->getDataPoints()->get_Item(0)->getLabel();
    $lbl->getDataLabelFormat()->setShowCategoryName(true);
    $lbl = $series->getDataPoints()->get_Item(1)->getLabel();
    $lbl->getDataLabelFormat()->setShowSeriesName(true);
    # 显示第三个标签的数值
    $lbl = $series->getDataPoints()->get_Item(2)->getLabel();
    $lbl->getDataLabelFormat()->setShowValue(true);
    $lbl->getDataLabelFormat()->setShowSeriesName(true);
    $lbl->getDataLabelFormat()->setSeparator("/");
    # 保存带图表的演示文稿
    $pres->save("output.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

创建散点图

散点图（亦称散点图或 x-y 图）常用于检查模式或展示两个变量之间的相关性。

使用散点图的情形：

• 您拥有成对的数值数据
• 您有两个配对良好的变量
• 您想确定两个变量是否相关
• 您有一个自变量对应因变量的多个取值

1. 按照 创建簇状柱形图 中的步骤操作。
2. 对于第三步，添加图表时使用以下任意一种图表类型：
   1. ChartType::ScatterWithMarkers - 表示散点图。
   2. ChartType::ScatterWithSmoothLinesAndMarkers - 表示通过曲线连接并带有数据标记的散点图。
   3. ChartType::ScatterWithSmoothLines - 表示通过曲线连接且不带数据标记的散点图。
   4. ChartType::ScatterWithStraightLinesAndMarkers - 表示通过直线连接并带有数据标记的散点图。
   5. ChartType::ScatterWithStraightLines - 表示通过直线连接且不带数据标记的散点图。

  # 实例化表示 PPTX 文件的演示文稿类
  $pres = new Presentation();
  try {
    # 访问第一张幻灯片
    $slide = $pres->getSlides()->get_Item(0);
    # 创建默认图表
    $chart = $slide->getShapes()->addChart(ChartType::ScatterWithSmoothLines, 0, 0, 400, 400);
    # 获取默认图表数据工作表索引
    $defaultWorksheetIndex = 0;
    # 获取图表数据工作表
    $fact = $chart->getChartData()->getChartDataWorkbook();
    # 删除演示系列
    $chart->getChartData()->getSeries()->clear();
    # 添加新系列
    $chart->getChartData()->getSeries()->add($fact->getCell($defaultWorksheetIndex, 1, 1, "Series 1"), $chart->getType());
    $chart->getChartData()->getSeries()->add($fact->getCell($defaultWorksheetIndex, 1, 3, "Series 2"), $chart->getType());
    # 获取第一条图表系列
    $series = $chart->getChartData()->getSeries()->get_Item(0);
    # 向系列添加新点 (1:3)
    $series->getDataPoints()->addDataPointForScatterSeries($fact->getCell($defaultWorksheetIndex, 2, 1, 1), $fact->getCell($defaultWorksheetIndex, 2, 2, 3));
    # 添加新点 (2:10)
    $series->getDataPoints()->addDataPointForScatterSeries($fact->getCell($defaultWorksheetIndex, 3, 1, 2), $fact->getCell($defaultWorksheetIndex, 3, 2, 10));
    # 更改系列类型
    $series->setType(ChartType::ScatterWithStraightLinesAndMarkers);
    # 更改图表系列标记
    $series->getMarker()->setSize(10);
    $series->getMarker()->setSymbol(MarkerStyleType::Star);
    # 获取第二条图表系列
    $series = $chart->getChartData()->getSeries()->get_Item(1);
    # 在此处添加新点 (5:2)
    $series->getDataPoints()->addDataPointForScatterSeries($fact->getCell($defaultWorksheetIndex, 2, 3, 5), $fact->getCell($defaultWorksheetIndex, 2, 4, 2));
    # 添加新点 (3:1)
    $series->getDataPoints()->addDataPointForScatterSeries($fact->getCell($defaultWorksheetIndex, 3, 3, 3), $fact->getCell($defaultWorksheetIndex, 3, 4, 1));
    # 添加新点 (2:2)
    $series->getDataPoints()->addDataPointForScatterSeries($fact->getCell($defaultWorksheetIndex, 4, 3, 2), $fact->getCell($defaultWorksheetIndex, 4, 4, 2));
    # 添加新点 (5:1)
    $series->getDataPoints()->addDataPointForScatterSeries($fact->getCell($defaultWorksheetIndex, 5, 3, 5), $fact->getCell($defaultWorksheetIndex, 5, 4, 1));
    # 更改图表系列标记
    $series->getMarker()->setSize(10);
    $series->getMarker()->setSymbol(MarkerStyleType::Circle);
    $pres->save("AsposeChart_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

创建饼图

饼图最适合用于显示数据的部分与整体关系，尤其是当数据包含带数值的分类标签时。然而，如果您的数据包含许多部分或标签，建议改用条形图。

1. 创建 Presentation 类的实例。
2. 使用索引获取幻灯片的引用。
3. 添加带有默认数据的图表，并指定 ChartType::Pie 类型。
4. 访问图表数据工作簿 ChartDataWorkbook。
5. 清除默认的系列和分类。
6. 添加新的系列和分类。
7. 为图表系列添加新的图表数据。
8. 为图表添加新点并为饼图的扇区应用自定义颜色。
9. 设置系列的标签。
10. 为系列标签启用引导线。
11. 设置饼图扇区的旋转角度。
12. 将修改后的演示文稿保存为 PPTX 文件。

  # 实例化表示 PPTX 文件的演示文稿类
  $pres = new Presentation();
  try {
    # 访问第一张幻灯片
    $slides = $pres->getSlides()->get_Item(0);
    # 添加带默认数据的图表
    $chart = $slides->getShapes()->addChart(ChartType::Pie, 100, 100, 400, 400);
    # 设置图表标题
    $chart->getChartTitle()->addTextFrameForOverriding("Sample Title");
    $chart->getChartTitle()->getTextFrameForOverriding()->getTextFrameFormat()->setCenterText(NullableBool::True);
    $chart->getChartTitle()->setHeight(20);
    $chart->setTitle(true);
    # 设置第一系列显示数值
    $chart->getChartData()->getSeries()->get_Item(0)->getLabels()->getDefaultDataLabelFormat()->setShowValue(true);

    $chart->getChartData()->getCategories()->add($fact->getCell(0, 3, 0, "3rd Qtr"));
    # 添加新系列
    $series = $chart->getChartData()->getSeries()->add($fact->getCell(0, 0, 1, "Series 1"), $chart->getType());
    # 填充系列数据
    $series->getDataPoints()->addDataPointForPieSeries($fact->getCell($defaultWorksheetIndex, 1, 1, 20));
    $series->getDataPoints()->addDataPointForPieSeries($fact->getCell($defaultWorksheetIndex, 2, 1, 50));
    $series->getDataPoints()->addDataPointForPieSeries($fact->getCell($defaultWorksheetIndex, 3, 1, 30));
    # 在新版本中不起作用
    # 添加新点并设置扇区颜色
    # series.IsColorVaried = true;
    $chart->getChartData()->getSeriesGroups()->get_Item(0)->setColorVaried(true);
    $point = $series->getDataPoints()->get_Item(0);
    $point->getFormat()->getFill()->setFillType(FillType::Solid);
    $point->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->CYAN);
    # 设置扇区边框
    $point->getFormat()->getLine()->getFillFormat()->setFillType(FillType::Solid);
    $point->getFormat()->getLine()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->GRAY);
    $point->getFormat()->getLine()->setWidth(3.0);
    $point->getFormat()->getLine()->setStyle(LineStyle->ThinThick);
    $point->getFormat()->getLine()->setDashStyle(LineDashStyle->DashDot);
    $point1 = $series->getDataPoints()->get_Item(1);
    $point1->getFormat()->getFill()->setFillType(FillType::Solid);
    $point1->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->ORANGE);
    # 设置扇区边框
    $point1->getFormat()->getLine()->getFillFormat()->setFillType(FillType::Solid);
    $point1->getFormat()->getLine()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->BLUE);
    $point1->getFormat()->getLine()->setWidth(3.0);
    $point1->getFormat()->getLine()->setStyle(LineStyle->Single);
    $point1->getFormat()->getLine()->setDashStyle(LineDashStyle->LargeDashDot);
    $point2 = $series->getDataPoints()->get_Item(2);
    $point2->getFormat()->getFill()->setFillType(FillType::Solid);
    $point2->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->YELLOW);
    # 设置扇区边框
    $point2->getFormat()->getLine()->getFillFormat()->setFillType(FillType::Solid);
    $point2->getFormat()->getLine()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
    $point2->getFormat()->getLine()->setWidth(2.0);
    $point2->getFormat()->getLine()->setStyle(LineStyle->ThinThin);
    $point2->getFormat()->getLine()->setDashStyle(LineDashStyle->LargeDashDotDot);
    # 为新系列的每个类别创建自定义标签
    $lbl1 = $series->getDataPoints()->get_Item(0)->getLabel();
    # lbl.ShowCategoryName = true;
    $lbl1->getDataLabelFormat()->setShowValue(true);
    $lbl2 = $series->getDataPoints()->get_Item(1)->getLabel();
    $lbl2->getDataLabelFormat()->setShowValue(true);
    $lbl2->getDataLabelFormat()->setShowLegendKey(true);
    $lbl2->getDataLabelFormat()->setShowPercentage(true);
    $lbl3 = $series->getDataPoints()->get_Item(2)->getLabel();
    $lbl3->getDataLabelFormat()->setShowSeriesName(true);
    $lbl3->getDataLabelFormat()->setShowPercentage(true);
    # 显示图表的引导线
    $series->getLabels()->getDefaultDataLabelFormat()->setShowLeaderLines(true);
    # 设置饼图扇区的旋转角度
    $chart->getChartData()->getSeriesGroups()->get_Item(0)->setFirstSliceAngle(180);
    # 保存带图表的演示文稿
    $pres->save("PieChart_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

创建折线图

折线图（亦称折线图）最适合用于展示随时间变化的数值。使用折线图，您可以一次比较大量数据、跟踪随时间的变化和趋势、突出数据系列中的异常等。

1. 创建 Presentation 类的实例。
2. 使用索引获取幻灯片的引用。
3. 添加带有默认数据的图表，并指定 ChartType::Line 类型。
4. 访问图表数据工作簿 (ChartDataWorkbook)。
5. 清除默认的系列和分类。
6. 添加新的系列和分类。
7. 为图表系列添加新的图表数据。
8. 将修改后的演示文稿保存为 PPTX 文件。

  $pres = new Presentation();
  try {
    $lineChart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Line, 10, 50, 600, 350);
    $pres->save("lineChart.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

默认情况下，折线图的点由直线连续相连。如果您希望点之间使用虚线而不是实线，可以按以下方式指定首选的虚线类型：

  $pres = new Presentation();
  try {
    $lineChart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Line, 10, 50, 600, 350);
    $seriesCollection = $lineChart->getChartData()->getSeries();
    foreach ($seriesCollection as $series) {
      $series->getFormat()->getLine()->setDashStyle(LineDashStyle::Dash);
    }
    $pres->save("lineChart.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

    $chart->getChartData()->getCategories()->clear();
    $chart->getChartData()->getSeries()->clear();
    $wb = $chart->getChartData()->getChartDataWorkbook();
    $wb->clear(0);
    # 分支 1
    $leaf = $chart->getChartData()->getCategories()->add($wb->getCell(0, "C1", "Leaf1"));
    $leaf->getGroupingLevels()->setGroupingItem(1, "Stem1");
    $leaf->getGroupingLevels()->setGroupingItem(2, "Branch1");
    $chart->getChartData()->getCategories()->add($wb->getCell(0, "C2", "Leaf2"));
    $leaf = $chart->getChartData()->getCategories()->add($wb->getCell(0, "C3", "Leaf3"));

    $series = $chart->getChartData()->getSeries()->add(ChartType::Treemap);
    $series->getLabels()->getDefaultDataLabelFormat()->setShowCategoryName(true);
    $series->getDataPoints()->addDataPointForTreemapSeries($wb->getCell(0, "D1", 4));
    $series->getDataPoints()->addDataPointForTreemapSeries($wb->getCell(0, "D2", 5));
    $series->getDataPoints()->addDataPointForTreemapSeries($wb->getCell(0, "D3", 3));

  try {
    # 访问第一张幻灯片标记
    $sld = $pres->getSlides()->get_Item(0);
    # 获取默认数据的图表
    $chart = $sld->getShapes()->get_Item(0);
    # 设置图表数据工作表的索引
    $defaultWorksheetIndex = 0;
    # 获取图表数据工作表
    $fact = $chart->getChartData()->getChartDataWorkbook();
    # 更改图表类别名称
    $fact->getCell($defaultWorksheetIndex, 1, 0, "Modified Category 1");
    $fact->getCell($defaultWorksheetIndex, 2, 0, "Modified Category 2");
    # 获取第一条图表系列
    $series = $chart->getChartData()->getSeries()->get_Item(0);
    # 现在更新系列数据
    $fact->getCell($defaultWorksheetIndex, 0, 1, "New_Series1");// 修改系列名称

    $series->getDataPoints()->get_Item(0)->getValue()->setData(90);
    $series->getDataPoints()->get_Item(1)->getValue()->setData(123);
    $series->getDataPoints()->get_Item(2)->getValue()->setData(44);
    # 获取第二条图表系列
    $series = $chart->getChartData()->getSeries()->get_Item(1);
    # 现在更新系列数据
    $fact->getCell($defaultWorksheetIndex, 0, 2, "New_Series2");// 修改系列名称

    $series->getDataPoints()->get_Item(0)->getValue()->setData(23);

    $chart->getChartData()->setRange("Sheet1!A1:B4");
    $pres->save("SetDataRange_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

在图表中使用默认标记

使用默认标记时，每个图表系列会自动获得不同的标记符号。

  $pres = new Presentation();
  try {
    $slide = $pres->getSlides()->get_Item(0);
    $chart = $slide->getShapes()->addChart(ChartType::LineWithMarkers, 10, 10, 400, 400);
    $chart->getChartData()->getSeries()->clear();
    $chart->getChartData()->getCategories()->clear();
    $fact = $chart->getChartData()->getChartDataWorkbook();
    $chart->getChartData()->getSeries()->add($fact->getCell(0, 0, 1, "Series 1"), $chart->getType());
    $series = $chart->getChartData()->getSeries()->get_Item(0);
    $chart->getChartData()->getCategories()->add($fact->getCell(0, 1, 0, "C1"));
    $series->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 1, 1, 24));
    $chart->getChartData()->getCategories()->add($fact->getCell(0, 2, 0, "C2"));
    $series->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 2, 1, 23));
    $chart->getChartData()->getCategories()->add($fact->getCell(0, 3, 0, "C3"));
    $series->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 3, 1, -10));
    $chart->getChartData()->getCategories()->add($fact->getCell(0, 4, 0, "C4"));
    $series->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 4, 1, null));
    $chart->getChartData()->getSeries()->add($fact->getCell(0, 0, 2, "Series 2"), $chart->getType());
    # 获取第二条图表系列
    $series2 = $chart->getChartData()->getSeries()->get_Item(1);
    # 现在填充系列数据
    $series2->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 1, 2, 30));
    $series2->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 2, 2, 10));
    $series2->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 3, 2, 60));
    $series2->getDataPoints()->addDataPointForLineSeries($fact->getCell(0, 4, 2, 40));
    $chart->setLegend(true);
    $chart->getLegend()->setOverlay(false);
    $pres->save("DefaultMarkersInChart.pptx", SaveFormat::Pptx);
