vb.net饼图,winform饼图

vb.net 控制excel画饼状图

我自己写的控件,里面有示例程序,很简单的。不过饼图只设置了12种颜色。。。只能显示12项

用vb.net可以做出饼图吗

Dim MyGraphics As Graphics = Me.PictureBox1.CreateGraphics

Dim MyBrush As New SolidBrush(Color.Red)

Dim MyProportion As Single

Dim MyRect As New Rectangle

Dim MyPoint As New PointF

Dim R As Single

Const PI = 3.1415926

MyGraphics.Clear(Color.White)

Dim MyStartAngel As Double

Dim MySweepAngel As Double

R = Math.Min(Me.PictureBox1.Width, Me.PictureBox1.Height) / 2 - 15

MyPoint.X = Me.PictureBox1.Width / 2

MyPoint.Y = Me.PictureBox1.Height / 2

MyRect.X = MyPoint.X - R

MyRect.Y = MyPoint.Y - R

MyRect.Width = R * 2

MyRect.Height = R * 2

MyStartAngel = 0

MyProportion = Val(TextBox7.Text)

MySweepAngel = MyProportion * 360 / PI

MyBrush.Color = Color.Red

MyGraphics.FillPie(MyBrush, MyRect, MyStartAngel, MySweepAngel)

' MyStartAngel = MyStartAngel + MySweepAngel

MyProportion = 0.75

MySweepAngel = 360 * MyProportion

MyBrush.Color = Color.Blue

MyGraphics.FillPie(MyBrush, MyRect, MyStartAngel, MySweepAngel)

vb.net中怎样曲线图,棒图,和饼图

vb2010以后的版本就自带Chart控件了,比如

Chart1.Series(0).ChartType = DataVisualization.Charting.SeriesChartType.Pie '饼图

我想问下,讲数据保存到excel中后,如何在VB.net中继续写代码,使得能够将这些数据生成一个饼图?并保存。

用宏功能啊,然后把宏代码(vb6.0)转化为Vb.net代码,有一个关键问题,就是VBA中的枚举类型在Vb.net中不适用,比如.End(xlUp)更改为.End(3)就能运行,另外vb.net中运行Excel对象不一定在点后会出现智能提示(即使你引用后也一样)你只要确定有该方法或者属性,直接写就是了,生成或者调试都是可以通过的
