拖一个PictureBox1控件 创建一个Paint事件。在事件中加入 Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint ' Create pens. Dim redPen As New Pen(Color.Red, 3) Dim greenPen As New Pen(Color.Green, 3) ' Create points that define curve. Dim point1 As New Point(50, 50) Dim point2 As New Point(100, 25) Dim point3 As New Point(200, 5) Dim point4 As New Point(250, 50) Dim point5 As New Point(300, 100) Dim point6 As New Point(350, 200) Dim point7 As New Point(250, 250) Dim curvePoints As Point() = {point1, point2, point3, point4, _ point5, point6, point7} ' Draw lines between original points to screen. e.Graphics.DrawLines(redPen, curvePoints) ' Draw curve to screen. e.Graphics.DrawCurve(greenPen, curvePoints) End Sub 得余册到数据后，改point的数据。漏颂然后返毁郑PictureBox1.Refresh()就行了

这个要用GDI+画。要看你点虐 版薯配本。
以下是VS2005中的顷启一段代码。
Me.PictureBox1.Height = 450
Me.PictureBox1.Width = 880
Dim gr As Graphics '定义画布
Dim bp As New Bitmap(880, 450) '定义位雀手如图,并进行赋值
Dim p As New Pen(Color.Black) '定义画笔
p.Width = 2 '宽度2
p.DashStyle = Drawing2D.DashStyle.Solid '样式直线
PictureBox1.Image = bp
gr = Graphics.FromImage(PictureBox1.Image)
gr.FillRectangle(Brushes.White, New Rectangle(0, 0, PictureBox1.Width, PictureBox1.Height))
gr.DrawLine(p, a, b, a, .Height - b) '绘制纵坐标
gr.DrawLine(p, a, .Height - b, .Width - a, .Height - b) '绘制横坐标
。net 其实还是很好绘制图形的
你可以看下 Graphics 类
Dim d As New Bitmap(Me.Width, Me.Height) ‘一个图片吧
Dim g As Graphics = Graphics.FromImage(d)’绘制 脊塌轮准备在这个图片是进行
然后 就是你绘制的东西了
线 就是 g.DrawLine()
圆 弧衫唤度 就用 g.DrawArc(Pens.Black, New Rectangle(0, 0, 400, 200), 0, 360)
复杂的就是 g.DrawBezier()
等 如果你用的是 VS的 编译 上面都有详细的参数说明
樱信 Dim d As New Bitmap(Me.Width, Me.Height)
Dim g As Graphics = Graphics.FromImage(d)
g.DrawArc(Pens.Black, New Rectangle(0, 0, 200, 200), 0, 360)
g.DrawLine(Pens.Red, New Point(0, 0), New Point(200, 200))
g.DrawLines(Pens.Green, New Point() {New Point(0, 0), New Point(50, 40), New Point(50, 80), New Point(90, 70), New Point(100, 400)})
g.DrawBezier(Pens.Yellow, New Point(0, 100), New Point(0, 0), New Point(200, 0）， New Point(200, 200))
g.Dispose()
Me.BackgroundImage = d
您好，您是想问vb点虐 连续绘制曲线图不消物亩失怎么办？b点虐 连续绘制曲线图不消失的解决办法如下：
1、首先必须罩烂森创建bitmap,关联到picturebox1.image上。
2、再在历腔picturebox1.image上创建Graphics,再进行作图。即可显示线图。
