推荐答案

 请使用插入代码块"(Insert Code Block)当您在帖子中插入代码时，可以使用编辑器顶部的按钮，以便我们阅读.

 Please use the "Insert Code Block" button at the top of the editor when you insert code into your posts so that we can read it.

 无论如何，您并未真正为我们提供足够的背景信息来了解何时何地进行此操作.我看不到要在何处设置ChartArea3DStyle的任何值来设置3DStyle的外观.这是我设置3DStyle的简单示例 到ChartArea以及如何打开/关闭3DStyle.也许它将帮助您了解代码中需要执行的操作.

 Anyways, you have not really given us enough context into when and where this is being done.  I do not see where you are setting any values of the ChartArea3DStyle to set the look of the 3DStyle.  Here is a simple example of how i set a 3DStyle to the ChartArea and how i can turn the 3DStyle On/Off.  Perhaps it will help you understand what you need to do in your code.

虽然我没有包含用于设置图表和添加数据点的代码.那真的不重要.

 I did not include the code i used for setting up my chart and add data points though. That really is not of importance.

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        'This adds a new ChartArea3DStyle for ChartArea(0) and sets the Rotation property
        Dim style As New DataVisualization.Charting.ChartArea3DStyle(Chart1.ChartAreas(0))
        style.Enable3D = True
        style.Rotation = 33
        Chart1.ChartAreas(0).Area3DStyle = style
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        'This just toggles the Enable3D property True/False
        Chart1.ChartAreas(0).Area3DStyle.Enable3D = Not Chart1.ChartAreas(0).Area3DStyle.Enable3D
    End Sub

 

 

 这就是它的作用...

 Here is what it does...
