Weard png output problem

[Nibbler <rea...@ho...>]

Hi.

I have weard problem. I have 2 files which I use. First file (file.txt)
includes all primary commands.
Second file (file2.txt) includes information (names of outputs and x/y-range
values).

Everything works fine (I get outputs: name.png and name2.png, but when I try
to look picture name.png in Dia-program
I get error:
Pixbuf[png] can't load: name.png

If I dont use file2.txt -> ( I'll write straight in file.txt:  set output
"name.png"
Then picture opens in Dia-program.

BUT picture: name2.png works every way. (either I use file2.txt OR I write
straight set output "name2.png in file.txt"

Whats wrong ? Why picture (name.png) is not a real picture ? (name is:
name.png, but it is not real a picture)
And the picture (name2.png) is a real picture and I can open it in
DIA-program ?

FILE.TXT

# These command make picture 1
set terminal png
call "file2.txt" $4  # HERE I READ WHAT WILL BE THE NAME OF THE PICTURE 1
bin = 1
set style fill solid 0.30 border
set xlabel 'title' tc lt 4
set ylabel 'title2' tc lt 4
load "file2.txt" $1 # I READ VALUES OF X-RANGE
load "file2.txt" $2 # I READ VALUES OF Y-RANGE

plot 'file.dat' using (bin*int($3/bin)):(1) title "Smooth frequencys" smooth
freq with boxes

reset
#these commands make picture2
call "file2.txt" $5 # HERE I READ WHAT WILL BE PICTURE2 NAME
set title "Something"
set xlabel 'title' tc lt 4
set ylabel 'title' tc lt 4
set xdata time
set format x "%m/%d\n %H:%M:\n%S"
set timefmt "%Y-%m-%d %H:%M:%S"

plot "file.dat" using 1:3 with filledcurve 1
reset 


FILE2.TXT


#comments
set xrange[:]
set yrange[:]
#comments
set output 'name.png' # NAME OF PICTURE 1
set output 'name2.png' # NAME OF PICTURE 2

You set the terminal to png. OK.

Then you call file2.txt, which contains the following

> FILE2.TXT
> set output 'name.png' # NAME OF PICTURE 1
> set output 'name2.png' # NAME OF PICTURE 2

So you open a file 'name.png', but do not write anything to it.
Then you immediately open a different file 'name2.png', which
closes the first, empty, file. Later you plot something.
After the plot you have an empty file 'name.png', and a 
file 'name2.png' containing a single plot.

Ok. 

Thanks Ethan Merritt.

I thought I can read one line from file at a time.

My plotFile contains two plot commands, so I solve this problem and I use
load-file command and 
I have two files where I can load commands.

example...

set output png
commands...
load "file1.txt" # this contains outputname, x-range etc..
plot...

set output png
set xrange [0:3]
load "file2.txt" # this contains yrange, outputname etc...
plot...

ANOTHER QUESTION:

Can I  increase the autoset yrange value ? 

What I means is can I somehow do like this:
yrange [0:autorange +3 ] ?

Now the yrange would be autorange + 3 ?
