The chart looks like this here, too, but is actually green-white, instead of green-black.
Re white/black, yeah I couldn't find a way to do that with the chart API and have it look right so I just flip those bits once I've pulled the chart into the buffer:
'flip black pixels to white to make up for charts api colour control
For y As Integer = 0 To gcimg.Height - 1
For x As Integer = 0 To gcimg.Width - 1
Dim clr As Color = gcimg.GetPixel(x, y)
If (CInt(clr.R) + clr.G + clr.B) < 50 Then
gcimg.SetPixel(x, y, Color.White)
End If
If x > 1 And x < 21 And y > 174 And y < 189 Then
gcimg.SetPixel(x, y, Color.FromArgb(37, 37, 38))
End If
Next x
Next y
