This is a library to compute optimally readable axis labels for terminal plots. The code is based on the axis_labels code of the Python plotting library uniplot.
It is implemented in Rust for performance reasons, since finding optimal axis labels is done by testing & scoring a large number of possible labels.
use axis_labels_rs::float_axis_labels;
let labels = float_axis_labels(0.0, 123.4, 60, 1, false, &String::from(" m"));
println!("{}", labels);
yields
0 m 50 m 100 m
