通過DevExpress WPF Controls，您能創(chuàng)建有著強(qiáng)大互動(dòng)功能的XAML基礎(chǔ)應(yīng)用程序，這些應(yīng)用程序?qū)Ｗ⒂诋?dāng)代客戶的需求和構(gòu)建未來新一代支持觸摸的解決方案。

本教程將指導(dǎo)您完成根據(jù)基礎(chǔ)數(shù)據(jù)源自動(dòng)創(chuàng)建3D系列所需的步驟。

應(yīng)該執(zhí)行以下步驟，本文我們將為大家介紹3個(gè)步驟及最后結(jié)果，更多完整內(nèi)容歡迎持續(xù)關(guān)注！

• Step 1. 編寫一個(gè)應(yīng)用程序
• Step 2. 添加圖表并將其綁定到數(shù)據(jù)
• Step 3. 自定義圖表外觀
• 結(jié)果

Step 3. 自定義圖表外觀

在此步驟中，您將學(xué)習(xí)如何配置外觀圖設(shè)置，為此請(qǐng)按照以下步驟操作。

• 要修改所有生成系列的外觀，請(qǐng)使用此系列模板。要?jiǎng)?chuàng)建新模板，請(qǐng)?jiān)赑roperties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(qǐng)找到屬性，然后在下拉列表中選擇Bubble3DSeriesView項(xiàng)目。

• 然后修改系列點(diǎn)表單，為此將屬性指定為對(duì)象。

• 將屬性定義為0.5，以設(shè)置最大氣泡大小。 將屬性定義為0.1，以設(shè)置最小氣泡大小。

結(jié)果

完成上述所有步驟后，您的代碼將顯示如下。
