Re: [Gnuplot-info] Call wgnuplot from C#

[Koto N. <kot...@gm...>]

Dear Roberto,

Thank you millions.
You fixed every problem I faced.  I spend very hard time to solve this
problem so I really appreciate you.

As a feed back for the future developer like me, let me write what I did.

>From C# call wgnuplot with command file as following:

  Process.Start("wgnuplot.exe", "command.gp");

Also in the command.gp file is made by following.  This was done at
the wgnuplot command line.

  plot "data.txt" using 1:3 title "testline" with linesp
  set terminal png size 320, 240
  set output "picture.png"
  replot
  set output
  set terminal windows
  save "command.gp"

Where data.txt is a file contains data, picture.png is a png file that
shows the plot of data's first colomn vs third colomn, and command.gp
has all commans above except the last line.

So when I run at the DOS window as:

  wgnuplot command.gp

Then I could get the picutre.png at the working directory without any
input at the command line of wgnuplot.

When the C# command runs, then I could get the picture.png file.  This
is very nice for C# since it could use the wgnuplot functions and use
the result.

Thank you very much again Roberto, now I can move on.

Regards,

Koto
