A fast and flexible command-line plotting tool that creates visualizations from data streams using gnuplot.
# Basic line plot
seq 100 | awk '{print $1, $1*2, $1*4}' | plot
# With headers
{echo "x y1 y2" && seq 100} | awk 'NR==1{print}NR>1{print $1, $1*2, $1*4}' | plot --headers
# Date-based time series
{echo "date value" && for i in {1..30}; do echo "2023-01-$i $((RANDOM % 100))"; done} | plot --dategit clone https://github.com/rushton/plot.git
