Re: [Gnuplot-bugs] Gnuplot 4.0 Win32 crashes on plot from file

[Uwe Z. <uw...@kt...>]

I might have been a bit confuse concerning the

  set datafile separator ","

since it is not mentioned in the index of the Gnuplot 4.0 help file.
The example given below works fine now again without giving the format
specifier in the using directive but by switching to comma as
separator character.

It appears that my newsreader treated the data file lines badly, so I
attach a sample data file...

UZ> Any ideas?
