I produce my graph with gnuplot and then pdflatex. I always used this header that has alwasy worked
set terminal epslatex standalone color size 4.0in,3.0in background rgb "white" set output 'plot.tex'
Unfortunately after having run
gnuplot plot.gnu && pdflatex plot.tex
I got the following error
pdfTeX warning: pdflatex (file ./pm-inc-eps-converted-to.pdf): PDF inclusion: found PDF version <1.7>, but at most version <1.5> allowed
Any idea how to solve it?
