用vb.net写一段代码。要求可以根据点坐标和对应值做出相应的彩色云图

以下是用VB.NET实现绘制彩色云图的代码。该代码基于WinForms框架，需要在Form上添加一个PictureBox控件用于绘制云图。

Private Sub DrawCloudChart(ByVal points As List(Of Point), ByVal values As List(Of Double), ByVal colors As List(Of Color))
    '获取点的最小值和最大值
    Dim minX As Double = points.Min(Function(p) p.X)
    Dim maxX As Double = points.Max(Function(p) p.X)
    Dim minY As Double = points.Min(Function(p) p.Y)
    Dim maxY As Double = points.Max(Function(p) p.Y)

    '创建位图并获取Graphics对象
    Dim bmp As New Bitmap(PictureBox1.Width, PictureBox1.Height)
    Dim g As Graphics = Graphics.FromImage(bmp)

    '绘制云图
    For i As Integer = 0 To points.Count - 2
        Dim x1 As Double = points(i).X
        Dim y1 As Double = points(i).Y
        Dim x2 As Double = points(i + 1).X
        Dim y2 As Double = points(i + 1).Y
        Dim v1 As Double = values(i)
        Dim v2 As Double = values(i + 1)
        Dim c1 As Color = colors(i)
        Dim c2 As Color = colors(i + 1)

        '根据点的坐标和对应值计算颜色插值
        Dim t As Double = (v1 + v2) / 2
        Dim r As Integer = CInt((c1.R * (v2 - t) + c2.R * (t - v1)) / (v2 - v1))
        Dim g As Integer = CInt((c1.G * (v2 - t) + c2.G * (t - v1)) / (v2 - v1))
        Dim b As Integer = CInt((c1.B * (v2 - t) + c2.B * (t - v1)) / (v2 - v1))
        Dim color As Color = Color.FromArgb(r, g, b)

        '绘制线段
        Dim pen As New Pen(color)
        g.DrawLine(pen, CInt((x1 - minX) / (maxX - minX) * PictureBox1.Width), CInt(PictureBox1.Height - (y1 - minY) / (maxY - minY) * PictureBox1.Height), CInt((x2 - minX) / (maxX - minX) * PictureBox1.Width), CInt(PictureBox1.Height - (y2 - minY) / (maxY - minY) * PictureBox1.Height))
    Next

    '显示位图
    PictureBox1.Image = bmp
End Sub

该方法接受三个列表作为参数：点的坐标、对应的值和颜色。其中，点的坐标和对应值应该一一对应，而颜色则是线段两端点对应值的颜色插值。代码中使用线性插值计算颜色，具体实现方法为在两端点对应值的平均值处计算颜色。最后，该方法将绘制好的位图显示在PictureBox控件上。
