vb.net繪座標圖 vb中坐标怎么写 _Text

vb.net怎么绘制带坐标轴的的一次函数？最好附上源码。1、利用公式求出Y值第一列设置表头为x，下面依次填入取值，比如x1234......第二例表头设置为y，在下面表格中填入计算公式如=2*x 1然后选中点右下角的十字型标记，拖下去，和前面x数量一致。2、然后选中数据源（即选中要进行操作的数据区域，这里指XY值所在区域。）3、执行菜单命令插入——图表——XY散点图执行命令，打开图表向导对话框选XY散点图－－选平滑线散点图－－完成最后使用图表向导在横坐标填入x值，纵坐标填入y值，生成图即可将一次函数的Y列用公式编辑出来，分别填写出当取不同的X值时得到不的函数值，选择函数值所在列，插入——图表按提示操作。执行菜单命令执行菜单命令
怎样在vb.net的picturebox里画出坐标?。?/h2>自己用GDI 画的无论什么什么尺寸的picturebox都行
不过别太小了o(∩_∩)o
代码放在哪里自己决定啊
最好是放在 picturebox的resize时间里
每次picturebox大小改变都重画一次坐标
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.X28, po.Y5, po.X30, po.Y5)
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.Y5)
g.DrawLine(p, po.X, po.Y2, po.X, po.Y)
po.X= (PictureBox1.Width - 100) / 8
Next
PictureBox1.Image = b
vb.net怎么绘制平面直角坐标系创建Graphics对象，可以调用CreateGraphics()直接做图也可以创建Bitmap对象然后调用Graphics.FromBitmap(b)得到Graphics G
G.Clear(Colors.Black)
G.DrawLine(Pens.White, 画线的坐标
如何用vb实现坐标图太好玩啦~~~~~哈哈终于完工啦

关于vb.net在picture.box里面画坐标图的TranslateTransform方法是用来平移对象的。如果你学过计算机图形学，有个偏移矩阵，就是它了。
你只要知道TranslateTranform(0,240)表示把图形移动到当前位置 (0,240)的地方就行了。
ScaleTransform用于缩放对象，1,1的话表示大小不变。
