解決方案，聯想的右對接（見下文底部對接）：它的工作，我也有每個系列線ChartDashStyle設置，以及指定一個傳奇的字體和大小。我修改了上面的代碼並調整了相當多的像素調整，以便將新圖例向上移動，並根據圖例的字體大小添加行之間的間距。我還添加了一些邏輯語句將ChartDashStyle轉換爲GDI + DashStyle。
在您動態創建例如Chart1對象，並處理所有代碼來填充系列等，所有你需要做的調用圖表的PostPaint事件是在所有圖表處理代碼末尾添加以下代碼：
Dim Chart1 As New Chart
Chart1.Invalidate()
Chart1.ChartAreas.Clear()
Chart1.Legends.Clear()
Chart1.Series.Clear()
.
.
(fill series datapoints, legend, titles, etc)
.
.
AddHandler Chart1.PostPaint, AddressOf Chart1_PostPaint
的繪畫後，PostPaint事件將觸發，然後調用方法（下面的子例程）用彩色線條重新創建圖例，並根據每個系列的相同屬性使用合適的粗細和虛線樣式。
（有不需要是在子程序的定義的端部的Handles...）
Private Sub Chart1_PostPaint(ByVal sender As Object, ByVal e As ChartPaintEventArgs)
If TypeOf e.ChartElement Is Legend Then
Dim c As Chart = CType(sender, Chart)
Dim g As Graphics = e.ChartGraphics.Graphics
'The legend
Dim l As Legend = c.Legends(0)
'Absolute dimensions of the legend (New legend will be based on this.. won't be exact.)
Dim pos As RectangleF = e.ChartGraphics.GetAbsoluteRectangle(l.Position.ToRectangleF)
'Absolute dimensions of one legend "cell"
Dim itemHeight As Single = pos.Height/c.Series.Count + 30
Dim itemWidth As Single = pos.Width/2
'Padding between line and text (horizontal) and each item (vertical)
Dim horizontalPadding As Single = 10
Dim verticalPadding As Single = l.Font.Size
Dim legendFont As Font = l.Font
'Draw a white box on top of the default legend to hide it
g.FillRectangle(Brushes.White, pos)
For i As Integer = 0 To c.Series.Count - 1
Dim s As Series = c.Series(i)
Dim p As New Pen(s.Color, CSng(Math.Min(s.BorderWidth, itemHeight))) 'Line no thicker than the item height.
Dim ds As ChartDashStyle = s.BorderDashStyle
'Line
Dim posY As Single = CSng(pos.Y + (verticalPadding * i + itemHeight * i + itemHeight/2)) - (c.Series.Count + 2) * verticalPadding
Dim startPoint As PointF = New PointF(pos.X, posY)
Dim endPoint As PointF = New PointF(CSng(pos.X + itemWidth), posY)
p.DashStyle = ds
If ds = ChartDashStyle.Solid Then
p.DashStyle = DashStyle.Solid
End If
If ds = ChartDashStyle.Dash Then
p.DashStyle = DashStyle.Dash
End If
If ds = ChartDashStyle.DashDot Then
p.DashStyle = DashStyle.DashDot
End If
If ds = ChartDashStyle.DashDotDot Then
p.DashStyle = DashStyle.DashDotDot
End If
g.DrawLine(p, startPoint, endPoint)
'Text
posY = CSng(pos.Y + verticalPadding * i + itemHeight * i) - (c.Series.Count + 2) * verticalPadding
startPoint = New PointF(CSng(pos.X + itemWidth), posY)
g.DrawString(s.Name, legendFont, Brushes.Black, startPoint.X + horizontalPadding + 5, startPoint.Y - 5)
Next
End If
End Sub

嘗試過，但因爲是動態創建的圖表手柄Chart1.PostPaint事件拋出異常。這不是一個簡單的按鈕，因此您需要在創建動態創建的Chart時建議如何在代碼中運行代碼。必須有一個解決方法（？） – wrtsvkrfm
