Every system call launches a new shubshell and runs the provided command in that shell. If you want to use system() in this way, you'll have to combine your shell commands into one, something like:

string cmd = "gnuplot; set term jpeg; ... ;exit";
system(cmd);

string cmd = "gnuplot; set term jpeg; ... ;exit";
system(cmd);
