Using a loop within gnuplot is the most efficient, but if it's proving to be too hard for you to maintain you could try using a bash/ksh loop and call gnuplot once for each file like this:

Code:
for file in *_data
do
   V=${file%_data}
   gnuplot <<EOF
set xlabel "year"
set ylabel "population"
set zlabel "country"
set title "${V}_survey"
set terminal png
set output "${V}.png"
splot "${V}_data" with lines
EOF
done

xpl2gpl

XPL2GPL(1)						      General Commands Manual							XPL2GPL(1)

NAME

       xpl2gpl - Convert tcptrace-style xplot input to gnuplot input.

SYNOPSIS

       xpl2gpl [-s] <file_name>

DESCRIPTION

       xpl2gpl	is a utility that converters tcptrace-style xplot input to gnuplot input.  This converter gives a nearly perfect gnuplot reproduc-
       tion of the corresponding xplot graph.

OPTIONS

       -s     Seperate files.  If you wish to plot only some data from the xpl file, you may use the -s option, which generates a bunch  of  data-
	      files filtered based on the color and plotting style.

EXAMPLES

       xpl2gpl foo.xpl

       This  would  produce files by the names "foo.gpl", "foo.datasets" and "foo.labels".  Load the file "file_name.gpl" in gnuplot and it should
       give you the plot.

NOTES

       xpl2gpl is provided for convenience, as gnuplot is more commonly installed than the xplot package  that	tcptrace  typically  expects,  and
       because xplot has not always been available in Debian. If possible, you should consider installing the xplot-xplot.org package and using it
       instead of using xpl2gpl.
