VB.net中如何在picturebox画线，有什么函数？
Dim b As New Bitmap(PictureBox1.Width, PictureBox1.Height)
Dim g As Graphics = Graphics.FromImage(b)
g.Clear(Color.White)
Dim p As New Pen(Color.Black)
p.EndCap = Drawing2D.LineCap.ArrowAnchor
g.DrawLine(p, 30, PictureBox1.Height - 30, 30, 30)
g.DrawLine(p, 30, PictureBox1.Height - 30, PictureBox1.Width - 30, PictureBox1.Height - 30)
Dim i As Integer
Dim bs As New SolidBrush(Color.Green)
Dim po As New Point
po.X = 0
po.Y = PictureBox1.Height - 35
For i = 700 To 1000 Step 50
g.DrawString(i, Me.Font, bs, po.X, po.Y)
g.DrawLine(p, po.X + 28, po.Y + 5, po.X + 30, po.Y + 5)
po.Y -= (PictureBox1.Height - 100) / 6
Next
po.X = 30
po.Y = PictureBox1.Height - 30
For i = 0 To 40 Step 5
g.DrawString(i, Me.Font, bs, po.X, po.Y + 5)
g.DrawLine(p, po.X, po.Y + 2, po.X, po.Y)
po.X += (PictureBox1.Width - 100) / 8
Next
PictureBox1.Image = b
vb.net绘制曲线图
。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 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
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
请问在VB6中该如何画多条曲线呢
Private Sub Form_Load()
MSChart1.chartType = VtChChartType2dLine
Dim arrValues()
ReDim arrValues(1 To 5, 1 To 6)
Dim i As Integer
For i = 1 To 5
arrValues(i, 1) = "t" i 'x轴
arrValues(i, 2) = 0 + Rnd * 100 '第一条线
arrValues(i, 3) = 0 + Rnd * 100 '第二条线
arrValues(i, 4) = 0 + Rnd * 100 '第三条线
arrValues(i, 5) = 0 + Rnd * 100 '第四条线
arrValues(i, 6) = 0 + Rnd * 100 '第五条线
Next i
MSChart1.ChartData = arrValues
