Re: plot a section of a splot

You can be selective about data values by using the ternary logical operator:

plot 'results' u 1:( $2 = 10 ? $2 : 1/0 ):3 t  "P_{max}(x,10)"

This will use your y values as data where y = 10, and 1/0 (undefined) otherwise, so that other points aren't plotted.

Note that this will only plot points.  Unless all your y=10 values are contiguous in the file, gnuplot will not draw lines between these points.
