Re: [Gnuplot-info] Can`t plot full range of the data file

[igor <igo...@ai...>]

Thank you! I will try.

You know, when I tried to run from the terminal
gnuplot -p Well.plt
everything went well.

But usually I'm running this from the Fortran code, and there are only 
three lines regarding Gnuplot plot (and these three lines are the same 
in all my programs except for the names of data file and plt file):

At the very beginning:
     character(len=*), parameter :: OUT_FILE = 'Well.txt'   ! Output file.
     character(len=*), parameter :: PLT_FILE = 'Well.plt'   ! Gnuplot file.
The very last line:
     call execute_command_line('gnuplot -p ' // PLT_FILE)

That's the only lines there which have any relations to Gnuplot. Fortran 
program writes data file and after that calls Gnuplot -
and I'm again getting aforementioned error! More than that, in some 
cases I'm getting plot from 0 to 2.8, in some cases - from 0 to 2.5, for 
this particular data from 0 to 1.9 while always data file has a range 
from 0 to 3.12.

So the reason looks like not in the Gnuplot itself - but may be you have 
any idea what it could be???

*SORRY! I'VE FOUND THE REASON!*

As always, it's very simple.
The line to write data file is:
     write (fu, *) Pi*m/180.0, m !.....

But this time I've forgot to put this line:
     close (fu)
before calling Gnuplot.

With this line everything is perfect.
Sorry, sorry, sorry.

Thank you very much for your attention!
