nu_plugin_plot

A small nu plugin to plot a list as a line graph.

Install

Not yet on crates.io, so you'll have to clone this repository. I assume you have Rust, and are inside a nushell instance.

git clone https://github.com/Euphrasiologist/nu_plugin_plot
cd nu_plugin_plot

cargo build --release
register ./target/release/nu_plugin_plot

# test commands
plot -h
hist -h
xyplot -h

Help

plot, hist, and xyplot have very similar helps, so I'll print out just plot here.

Render an ASCII plot from a list of values.

Usage:
  > plot {flags}

Flags:
  -h, --help - Display the help message for this command
  --width <Number> - The maximum width of the plot.
  --height <Number> - The maximum height of the plot.
  -t, --title <String> - Provide a title to the plot.
  -l, --legend - Plot a tiny, maybe useful legend.
  -b, --bars - Change lines to bars.
  -s, --steps - Change lines to steps.
  -p, --points - Change lines to points.

Examples

in the following, we define a bunch of sine wave as follows

let one = (seq 0.0 0.01 20.0 | math sin)
let two = (seq 1.0 0.01 21.0 | math sin)
let three = (seq 2.0 0.01 22.0 | math sin)
let four = (seq 3.0 0.01 23.0 | math sin)

Basic plots

• plot a single line

If you've got R installed (& Rscript)

go crazy! forget ggplot!

let x = (Rscript -e "cat(dnorm(seq(-4, 4, length=100)))" | into string | split row ' ' | into decimal)
let y = (Rscript -e "cat(dnorm(seq(-3, 6, length=100)))" | into string | split row ' ' | into decimal)

[$x $y] | plot -bl -t "Two normal distributions"

Features

Plot:

• a single numeric list
• a list of numeric lists
  • with colour support
  • with legend
  • with title
• scatter plots (as a list of two numeric lists)
• histogram (list rendered as a bar chart)
• nested xyplot (i.e. multiple xyplots on the same plot...)
• records..?

Please help me make this better! Submit issues/PR's, happy to chat.

The color rendering inside nushell is slightly confusing - you may notice I've included my own modified copies of textplots and drawille in the source code. This is because their color rendering method was not working inside the plugin - I still don't know why.
