WPF界面開發(fā)工具DevExpress WPF使用教程：創(chuàng)建綁定到數(shù)據(jù)的3D圖表控件（第三部分）

通過DevExpress WPF Controls，您能創(chuàng)建有著強大互動功能的XAML基礎(chǔ)應(yīng)用程序，這些應(yīng)用程序?qū)Ｗ⒂诋敶蛻舻男枨蠛蜆?gòu)建未來新一代支持觸摸的解決方案。

在本教程中，您將完成可視化數(shù)據(jù)源所需的步驟。

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. 編寫一個應(yīng)用程序
Step 2. 為圖表和系列綁定添加數(shù)據(jù)
Step 3. 配置系列視圖
結(jié)果

Step 3. 配置系列視圖

本節(jié)中系列的外觀將被配置，將分配一個不同的系列視圖。此外，通過點的ColorIndex值對點進行著色的著色器將用于提供顏色。

打開Series Collection Editor然后選擇Series3D，找到屬性并將其設(shè)置為.。

展開視圖屬性，找到屬性并將其分配給對象。

然后，展開model屬性，并將其屬性設(shè)置為Low，這將提高應(yīng)用程序性能。

找到屬性并將其設(shè)置為。

擴展著色器的屬性并將其設(shè)置為-0.4 0.4 1.8 2。

將對象指定為屬性值。

將設(shè)置為true。

最后，將設(shè)置為新的對象，然后單擊OK關(guān)閉編輯器并保存更改。

當前，該系列的XAML標記應(yīng)如下所示。

<dxc:Series3D DisplayName="Series 1">
<dxc:Series3D.View>
<dxc:Point3DSeriesView>
<dxc:Point3DSeriesView.MarkerModel>
<dxc:Marker3DSpherePointModel SphereDetalizationLevel="Low"/>
</dxc:Point3DSeriesView.MarkerModel>
<dxc:Point3DSeriesView.Colorizer>
<dxc:RangeColorizer3D RangeStops="-0.4 0.4 1.8 2" 
ApproximateColors="True">
<dxc:RangeColorizer3D.ValueProvider>
<dxc:ColorObjectValueProvider3D/>
</dxc:RangeColorizer3D.ValueProvider>
<dxc:RangeColorizer3D.Palette>
<dxc:YellowPalette/>
</dxc:RangeColorizer3D.Palette>
</dxc:RangeColorizer3D>
</dxc:Point3DSeriesView.Colorizer>
</dxc:Point3DSeriesView>
</dxc:Series3D.View>
<!--Point Source Configuration -->
</dxc:Series3D>

結(jié)果

下圖演示了已啟動的應(yīng)用程序。

以下代碼是本入門課程的結(jié)果。
