PowerPoint 簡報中的圖表

這些圖表為我們提供了一個快速而簡明的機制來呈現統計數據。它使相關利益相關者能夠迅速做出關鍵決策。這些圖表由數據及其相應類別組成。因此，像是在 PowerPoint 中添加、更新和刪除圖表數據的操作。其相關類別也可以使用 Aspose.Slides Cloud API 來執行。

此外，為了使用 SDK，您需要安裝它，而最簡便的方法是通過 NuGet 庫。因此，請嘗試在套件管理器控制台上使用以下命令

 Install-Package Aspose.Slides-Cloud -Version 21.2.0

Cloud API 也可以透過終端機使用 cURL 命令訪問。因此，為了訪問它們，您需要提供一個基於您的 Client ID 和 Client Secret 生成的 JWT 令牌。因此，我們建議您訪問以下鏈接以進一步了解。

處理圖表類別

這個新資源是形狀的子資源。它僅適用於支持類別的圖表形狀(柱狀圖、折線圖等)。它允許我們一起添加、修改和刪除圖表類別以及相關的數據點。本文主要集中於以下主題

為圖表新增類別

Chart chart = api.PutChartCategory(request);
Console.WriteLine(chart.Categories.Count);

刪除圖表類別

Aspose.Slides Cloud API 也提供了刪除圖表物件中任何現有類別的功能。您只需提供幻燈片的索引、相應的形狀索引以及相關的類別 ID 來滿足要求。

請求 URL

<code>DELETE https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/slides/1/shapes/1/categories/2?folder=myFolder</code>

C#.NET

string MyAppKey = "xxxxxxxx";    // Get AppKey and AppSID from https://dashboard.aspose.cloud/
string MyAppSid = "xxxxxxxx";    // Get AppKey and AppSID from https://dashboard.aspose.cloud/

SlidesApi api = new SlidesApi(MyAppSid, MyAppKey);
DeleteChartCategoryRequest request = new DeleteChartCategoryRequest
{
    Name = "myPresentaion.pptx",
    Folder = "myFolder",
    SlideIndex = 1,
    ShapeIndex = 1,
    CategoryIndex = 2
};
Chart chart = api.DeleteChartCategory(request);
Console.WriteLine(chart.Categories.Count);

處理圖表數據

該 API 完全能夠提供操作與 PowerPoint 幻燈片中的圖表物件相關的資料點的功能。根據最近對 API 的更新，新的資源是系列的子資源。它僅適用於圖表形狀，並允許我們新增、修改和刪除個別資料點。

將數據點添加到圖表系列中

這適用於散點圖和氣泡圖系列。您不能為單值系列創建數據點，除非創建相關類別。

 ShapeIndex = 1,
 SeriesIndex = 2,
 DataPoint = dto
};
Chart chart = api.PostChartDataPoint(request);
Console.WriteLine(((ScatterSeries)chart.Series[1]).DataPoints.Count);

更新圖表資料點

您也可以使用 API 來更新現有的圖表數據點。

 DataPoint = dto
};
Chart chart = api.PutChartDataPoint(request);
Console.WriteLine(((ScatterSeries)chart.Series[1]).DataPoints[1].XValue); //5.5

刪除圖表數據點

對於 Chart 物件中的所有現有數據點，API 還允許您通過提供 PointIndex 的值來刪除任何點。
