在 C++ 中创建或更新 PowerPoint 演示文稿图表

本页内容简介

使用 Aspose.Slides for C++ 在 PowerPoint 演示文稿中创建和自定义图表。通过实用的 C++ 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全面指南。您将学习如何以编程方式将图表添加到幻灯片、填充数据，并应用各种格式选项以满足特定设计需求。全文提供详细的代码示例，展示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。遵循本指南，您将深入了解如何在应用程序中集成动态图表生成，从而简化创建数据驱动的演示文稿的过程。

创建图表

图表帮助人们快速可视化数据并获取洞察，这些信息可能在表格或电子表格中并不立即显现。

为什么要创建图表？

使用图表，您可以

• 在演示文稿的单张幻灯片上聚合、压缩或汇总大量数据
• 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向
• 发现异常值、偏差、误差、无意义的数据等
• 传达或展示复杂数据

在 PowerPoint 中，您可以通过“插入”功能创建图表，该功能提供用于设计多种图表的模板。使用 Aspose.Slides，您可以创建常规图表（基于流行的图表类型）和自定义图表。

为了让您能够创建图表，Aspose.Slides 在 Aspose::Slides::Charts 命名空间下提供了 ChartType 枚举类。此枚举类的值对应不同的图表类型。

创建普通图表

1. 创建 Presentation 类的实例。
2. 通过索引获取幻灯片的引用。
3. 添加带有数据的图表并指定您偏好的图表类型。
4. 为图表添加标题。
5. 访问图表数据工作表。
6. 清除所有默认的系列和类别。
7. 添加新的系列和类别。
8. 为图表系列添加一些新的图表数据。
9. 为图表系列添加填充颜色。
10. 为图表系列添加标签。
11. 将修改后的演示文稿写入为 PPTX 文件。

创建散点图

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

您可能想在以下情况下使用散点图

• 您拥有成对的数值数据
• 您有两个配对良好的变量
• 您想确定这两个变量是否相关
• 您有一个独立变量对应于因变量的多个取值

创建饼图

饼图最适合用于显示数据的整体与部分之间的关系，尤其是数据包含带数值的分类标签时。不过，如果您的数据包含大量部分或标签，您可能需要考虑改用条形图。

1. 创建 Presentation 类的实例。
2. 通过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所需类型（此处为 ChartType.Pie）。
4. 访问图表数据 IChartDataWorkbook。
5. 清除默认的系列和类别。
6. 添加新的系列和类别。
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添加自定义颜色。
9. 为系列设置标签。
10. 为系列标签设置引导线。
11. 设置饼图幻灯片的旋转角度。
12. 将修改后的演示文稿写入 PPTX 文件

创建折线图

折线图（也称为折线图）在您想展示随时间变化的数值时最为适用。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. 通过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所需类型（此处为 ChartType::Line）。
4. 访问图表数据 IChartDataWorkbook。
5. 清除默认的系列和类别。
6. 添加新的系列和类别。
7. 为图表系列添加新的图表数据。
8. 将修改后的演示文稿写入 PPTX 文件

下面的 C++ 代码演示如何创建折线图：

#include <DOM/Chart/ChartType.h>
#include <DOM/IChart.h>
#include <DOM/IShapeCollection.h>
#include <DOM/ISlide.h>
#include <DOM/ISlideCollection.h>
#include <DOM/Presentation.h>
#include <Export/SaveFormat.h>
using namespace Aspose::Slides;
using namespace Aspose::Slides::Charts;
using namespace Aspose::Slides::Export;

auto pres = System::MakeObject<Presentation>();

System::SharedPtr<IChart> lineChart = pres->get_Slides()->idx_get(0)->get_Shapes()->AddChart(ChartType::Line, 10.0f, 50.0f, 600.0f, 350.0f);
pres->Save(u"lineChart.pptx", SaveFormat::Pptx);

默认情况下，折线图的点通过直线连续相连。如果您希望点之间使用虚线相连，可以按以下方式指定首选的虚线类型：

#include <DOM/Chart/ChartType.h>
#include <DOM/Chart/IChartData.h>
#include <DOM/Chart/IChartSeries.h>
#include <DOM/Chart/IChartSeriesCollection.h>
#include <DOM/Chart/IFormat.h>
#include <DOM/IChart.h>
#include <DOM/ILineFormat.h>
#include <DOM/IShapeCollection.h>
#include <DOM/ISlide.h>
#include <DOM/ISlideCollection.h>
#include <DOM/LineDashStyle.h>
#include <DOM/Presentation.h>
using namespace Aspose::Slides;
using namespace Aspose::Slides::Charts;

auto pres = System::MakeObject<Presentation>();

System::SharedPtr<IChart> lineChart = pres->get_Slides()->idx_get(0)->get_Shapes()->AddChart(ChartType::Line, 10.0f, 50.0f, 600.0f, 350.0f);
for (auto&& series : lineChart->get_ChartData()->get_Series())
{
    series->get_Format()->get_Line()->set_DashStyle(LineDashStyle::Dash);
}

创建树形图

树形图在您想展示数据类别的相对大小并同时快速引起对每个类别中大型贡献项的注意时最为适用。

1. 创建 Presentation 类的实例。
2. 通过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所需类型（此处为 ChartType.TreeMap）。
4. 访问图表数据 IChartDataWorkbook。
5. 清除默认的系列和类别。
6. 添加新的系列和类别。
7. 为图表系列添加新的图表数据。
8. 将修改后的演示文稿写入 PPTX 文件

更新图表

1. 实例化表示包含该图表的演示文稿的 Presentation 类。
2. 通过索引获取幻灯片的引用。
3. 遍历所有形状以找到目标图表。
4. 访问图表数据工作表。
5. 通过更改系列值来修改图表数据系列数据。
6. 添加新系列并为其填充数据。
7. 将修改后的演示文稿写入为 PPTX 文件。

下面的 C++ 代码演示如何更新图表：

#include <DOM/Chart/IChartData.h>
#include <DOM/Chart/IChartDataPoint.h>

using namespace Aspose::Slides;
using namespace Aspose::Slides::Charts;

// 实例化表示 PPTX 文件的 Presentation 类
System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"ExistingChart.pptx");

// 访问第一张幻灯片
System::SharedPtr<ISlide> sld = pres->get_Slides()->idx_get(0);

// 添加带有默认数据的图表
System::SharedPtr<IChart> chart = System::ExplicitCast<Aspose::Slides::Charts::IChart>(sld->get_Shapes()->idx_get(0));

// 设置图表数据工作表的索引
int32_t defaultWorksheetIndex = 0;

// 获取图表数据工作表
System::SharedPtr<IChartDataWorkbook> fact = chart->get_ChartData()->get_ChartDataWorkbook();


// 更改图表类别名称
fact->GetCell(defaultWorksheetIndex, 1, 0, System::ObjectExt::Box<System::String>(u"Modified Category 1"));
fact->GetCell(defaultWorksheetIndex, 2, 0, System::ObjectExt::Box<System::String>(u"Modified Category 2"));

// 获取第一个图表系列
System::SharedPtr<IChartSeries> series = chart->get_ChartData()->get_Series()->idx_get(0);

// 更新系列数据
fact->GetCell(defaultWorksheetIndex, 0, 1, System::ObjectExt::Box<System::String>(u"New_Series1"));
// 修改系列名称
series->get_DataPoints()->idx_get(0)->get_Value()->set_Data(System::ObjectExt::Box<int32_t>(90));
series->get_DataPoints()->idx_get(1)->get_Value()->set_Data(System::ObjectExt::Box<int32_t>(123));
series->get_DataPoints()->idx_get(2)->get_Value()->set_Data(System::ObjectExt::Box<int32_t>(44));

// 获取第二个图表系列
series = chart->get_ChartData()->get_Series()->idx_get(1);

// 现在更新系列数据
fact->GetCell(defaultWorksheetIndex, 0, 2, System::ObjectExt::Box<System::String>(u"New_Series2"));
// 修改系列名称
series->get_DataPoints()->idx_get(0)->get_Value()->set_Data(System::ObjectExt::Box<int32_t>(23));
series->get_DataPoints()->idx_get(1)->get_Value()->set_Data(System::ObjectExt::Box<int32_t>(67));
series->get_DataPoints()->idx_get(2)->get_Value()->set_Data(System::ObjectExt::Box<int32_t>(99));


// 现在，添加新系列
chart->get_ChartData()->get_Series()->Add(fact->GetCell(defaultWorksheetIndex, 0, 3, System::ObjectExt::Box<System::String>(u"Series 3")), chart->get_Type());

// 获取第三个图表系列
series = chart->get_ChartData()->get_Series()->idx_get(2);

// 现在填充系列数据
series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 1, 3, System::ObjectExt::Box<int32_t>(20)));
series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 2, 3, System::ObjectExt::Box<int32_t>(50)));

chart->set_Type(Aspose::Slides::Charts::ChartType::ClusteredCylinder);

// 保存包含图表的演示文稿
pres->Save(u"AsposeChartModified_out.pptx", Aspose::Slides::Export::SaveFormat::Pptx);

设置图表的数据范围

要检查现有图表已使用的范围，请参阅检索图表的数据范围。

1. 打开包含图表的 Presentation 实例。
2. 通过索引获取幻灯片的引用。
3. 遍历所有形状以找到目标图表。
4. 访问图表数据并设置范围。
5. 将修改后的演示文稿保存为 PPTX 文件。

下面的 C++ 代码演示如何设置图表的数据范围：

#include <DOM/Chart/IChartData.h>
#include <DOM/IChart.h>
#include <DOM/IShapeCollection.h>
#include <DOM/ISlide.h>
#include <DOM/ISlideCollection.h>
#include <DOM/Presentation.h>
#include <Export/SaveFormat.h>
#include <system/string.h>
using namespace Aspose::Slides;
using namespace Aspose::Slides::Charts;
using namespace Aspose::Slides::Export;
using namespace System;

// 文档目录的路径。
String dataDir = u"../documents/";

// 实例化表示 PPTX 文件的 Presentation 类
auto presentation = System::MakeObject<Presentation>(dataDir + u"ExistingChart.pptx");

// 访问第一张幻灯片并添加带有默认数据的图表
auto slide = presentation->get_Slides()->idx_get(0);
auto chart = System::ExplicitCast<IChart>(slide->get_Shapes()->idx_get(0));
chart->get_ChartData()->SetRange(u"Sheet1!A1:B4");
presentation->Save(dataDir + u"SetDataRange_out.pptx", SaveFormat::Pptx);

在图表中使用默认标记

当您在图表中使用默认标记时，每个图表系列会自动获得不同的默认标记符号。

下面的 C++ 代码演示如何自动设置图表系列的标记：

#include <DOM/Chart/ChartType.h>

常见问题

Aspose.Slides 支持哪些图表类型？

Aspose.Slides 支持广泛的图表类型，包括柱形图、折线图、饼图、面积图、散点图、直方图、雷达图等。这种灵活性使您可以根据数据可视化需求选择最合适的图表类型。

如何向幻灯片添加新图表？

要添加图表，首先创建 Presentation 类的实例，使用索引检索所需幻灯片，然后调用添加图表的方法，指定图表类型和初始数据。此过程直接将图表集成到演示文稿中。

如何更新图表中显示的数据？

您可以通过访问其数据工作簿 (IChartDataWorkbook)，清除任何默认的系列和类别，然后添加自定义数据来更新图表的数据。这使您能够以编程方式刷新图表以反映最新数据。

是否可以自定义图表的外观？

是的，Aspose.Slides 提供了广泛的自定义选项。您可以修改颜色、字体、标签、图例和其他格式元素，以根据特定的设计要求定制图表的外观。
