图表显示模式

1.2 2D图表

[C#.Net]

tChart1.Aspect.View3D = false;

[VB.Net]

TChart1.Aspect.View3D = False

使用2D图表不会出现任何特殊问题，所有对象坐标都是相对于图表面板或图表矩形的位置，不需要对3D偏移进行任何限制。

1.3 3D正交图

[C#.Net]

private void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g) {        Point p1 = new Point(tChart1.Axes.Left.Position, tChart1.Axes.Top.Position);        Point p2 = new Point(tChart1.Axes.Right.Position, tChart1.Axes.Bottom.Position);        g.MoveTo(p1);        g.LineTo(p2, 0);}

[VB.Net]

Private Sub TChart1_AfterDraw(ByVal sender As Object, ByVal g As Steema.TeeChart.Drawing.Graphics3D) Handles TChart1.AfterDraw        Dim P1 As New Point(TChart1.Axes.Left.Position, TChart1.Axes.Top.Position)        Dim P2 As New Point(TChart1.Axes.Right.Position, TChart1.Axes.Bottom.Position)        g.MoveTo(P1)        g.LineTo(P2, 0)End Sub

此示例在图表中绘制一条对角线，并刷新到图表的背面

[C#.Net]

        int width3D = tChart1.Aspect.Width3D;        Point p1 = new Point(tChart1.Axes.Left.Position, tChart1.Axes.Top.Position);        Point p2 = new Point(tChart1.Axes.Right.Position, tChart1.Axes.Bottom.Position);        g.MoveTo(p1, width3D);        g.LineTo(p2, width3D);}

[VB.Net]

Private Sub TChart1_AfterDraw(ByVal sender As Object, ByVal g As Steema.TeeChart.Drawing.Graphics3D) Handles TChart1.AfterDraw        Dim Width3D As Integer = TChart1.Aspect.Width3D        Dim P1 As New Point(TChart1.Axes.Left.Position, TChart1.Axes.Top.Position)        Dim P2 As New Point(TChart1.Axes.Right.Position, TChart1.Axes.Bottom.Position)        g.MoveTo(P1, Width3D)        g.LineTo(P2, Width3D)End Sub

在运行时使用3D图表的显示属性时使用Aspect界面（*注意：并非所有选项都可用于正交图表）。

1.4 3D“原生”Windows图表

原生Windows模式3D提供图表旋转和高度90°，您可以放大和缩小整个图表。通过取消选择3D Editor页面上的Orthogonal复选框，在设计时为TeeChart选择Native Windows mode 3D。

[C#.Net]

tChart1.Aspect.Orthogonal = false;

[VB.Net]

TChart1.Aspect.Orthogonal = False
