概述：通過DevExpress WPF Controls，您能創建有著強大互動功能的XAML基礎應用程序。本文將為大家介紹使用自動生成的序列創建3D圖表，DevExpress WPF v20.2震撼，歡迎下載體驗新版！

# 界面/圖表報表/文檔/IDE等千款熱門軟控件火熱銷售中 >>

通過DevExpress WPF Controls，您能創建有著強大互動功能的XAML基礎應用程序，這些應用程序專注于當代客戶的需求和構建未來新一代支持觸摸的解決方案。

本教程將指導您完成根據基礎數據源自動創建3D系列所需的步驟。

應該執行以下步驟，本文我們將為大家介紹3個步驟及最后結果，更多完整內容歡迎持續關注！

Step 1. 編寫一個應用程序
Step 2. 添加圖表并將其綁定到數據
Step 3. 自定義圖表外觀
結果

Step 3. 自定義圖表外觀

在此步驟中，您將學習如何配置外觀圖設置，為此請按照以下步驟操作。

要修改所有生成系列的外觀，請使用此系列模板。要創建新模板，請在Properties窗口中找到屬性，然后單擊New按鈕。

然后，更改系列視圖。為此請找到屬性，然后在下拉列表中選擇Bubble3DSeriesView項目。

然后修改系列點表單，為此將屬性指定為對象。

將屬性定義為0.5，以設置最大氣泡大小。將屬性定義為0.1，以設置最小氣泡大小。

結果

完成上述所有步驟后，您的代碼將顯示如下。
