[求助] vb.net调用gnuplot并且load参数文件

Dim gnu As New ProcessStartInfo(Application.StartupPath & ".\gnuplot\bin\gnuplot.exe")
With gnu
    gnu.Verb = "load"
    gnu.Arguments = ".\experiment-3\Rjhplot.plt"
    gnu.FileName = ".\experiment-3\Rjhplot.plt"
    gnu.RedirectStandardError = True
    gnu.RedirectStandardOutput = True
    gnu.UseShellExecute = False
    gnu.CreateNoWindow = False
End With
Dim g As Process = Process.Start(gnu)
Dim gOutput As String = g.StandardOutput.ReadToEnd()
Dim gError As String = g.StandardError.ReadToEnd()
g.WaitForExit()
配置文件内容如下：
set key off
  set xlabel "t (min)" offset 0,1 font 'Times,11'
  set ylabel "T (K)" offset 3,0 font 'Times,11'
  set title "T-t Graph for Renald Correction" offset 0,-0.5 font 'Times,14'
  set decimalsign "."
  set format x "%.2f"
  set format y "%.2f"
  set xtics offset 0,0.5   
  plot "Rjhdata.txt" using 1:2 with linespoints linetype -1
