Inject colors in graphs generated by gnuplot in term dumb plot mode
Solution 1
Use grep --colors=always <pattern>, it uses grep default color highlighting.
> gnuplot5 -e "set term dumb 70 20; plot 'file1' pt '@'" | grep --color=always '@'Solution 2
Use colout <pattern> <color>. It has the ability to select the color but a python library has to be installed (pip install colout).
> gnuplot5 -e "set term dumb 70 20; plot 'file1' pt '@'" | colout '@' green
