2.1 Configuration

2.1.1 set term x11 fails

gnuplot> set term x11

Terminal type is now 'x11'
Options are ' nopersist enhanced'
gnuplot> Expected X11 driver: /home/jcshi/Softwares/gnuplot-5.2.8/libexec/gnuplot/5.2/gnuplot_x11
Exec failed: No such file or directory
See 'help x11' for more details

It reports that it cannot find the X11 driver. We need to set an environment variable.

export GNUPLOT_DRIVER_DIR=/opt/ohpc/pub/utils/gnuplot/5.2.8/libexec/gnuplot/5.2
gnuplot> set term x11
