Passing a GNUplot variable to system(/usr/bin/awk)

Show all headers | View raw

This line in GNUplot works fine:

system("/usr/bin/awk '/-1.98/{print $2 $1}' /path/to/myfile.txt")

But how would I pass a variable from GNUplot into that in place of the -1.98 value? 

For example, using STATS_max_y from a plot command:

system("/usr/bin/awk '/STATS_max_y/{print $2 $1}' /path/to/myfile.txt")

That (and its variants) don't work, and I can't work out the formatting to do this correctly.
