GNUplot with sixel support
On debian, just use these binaries (gnuplot backported from debian testing) or make your own using the attached patch or by adding to debian rules “–with-bitmap-terminals” right after –with-gd, so that debian/rules looks like:
–with-gd –with-bitmap-terminals
Then set GNUTERM, like:
export GNUTERM=”sixelgd size 1280,720 truecolor font arial 10″
You can mix regular images, ANSI colors and plot of function
