PPTX 用 C++ 格式化圖表
使用 C++ API 的服務器端 Aspose.Slides 的原生和高性能 PPTX 文檔圖表，無需使用 Microsoft 或 Adobe PDF 等任何軟件。
Aspose.Slides for C++
Overview
如何使用 C++ 創建 PPTX 文件圖表
為了搜索 PPTX 文件，我們將使用
API 是一個功能豐富、功能強大且易於使用的 C++ 平台文檔搜索 API。可以直接下載最新版本，直接打開
包管理器，搜索 Aspose.Slides.Cpp 並安裝。您還可以從包管理器控制台使用以下命令。
命令
PM> Install-Package Aspose.Slides.Cpp
在 C++ 中創建 PPTX 文件圖表的步驟
只需幾行代碼即可使用 Aspose.Slides for C++ API 繪製基本文檔圖表。
實例化演示類。
訪問第一張幻燈片。
添加帶有默認數據的圖表
設置圖表數據表的索引。
獲取圖表數據工作簿。
設置圖表標題。
刪除默認生成的系列和類別。
添加系列和類別。
獲取第一個圖表系列並填充數據。
為系列設置填充顏色。
保存 PPTX 文件。
