nuplot

nuplot is a nushell plugin for plotting charts. It builds interactive charts from your data that are opened inside the web browser.

Features

• Supported chart types:
  • Line chart
  • Bar chart
  • Stacked bar chart
  • Pie chart
  • Boxplot chart
  • Kline chart
• Chart title, size and color theme can be adjusted
• Configure, which series is used for the x-axis

Examples

A Simple Pie chart

{'apples': 7 'oranges': 5 'bananas': 3} | nuplot pie --title "Fruits"

Show weather forcast from wttr.in as bar chart

http get http://wttr.in?format=j1
| get weather
| select date avgtempC
| each {|l| {date: ($l.date | into datetime) avgtempC: ($l.avgtempC | into int)} }
| nuplot bar --xaxis date --title "Weather forcast"

The data type conversion for avgtempC is needed, because nuplot only shows series of numbers. The data type conversion of the date column can be omitted but will lead to warnings in the moment because the date format is not recognized correctly.

Show the average monthly temperatures as a boxplot chart

http get https://bulk.meteostat.net/v2/hourly/2024/10389.csv.gz
| gunzip
| from csv --noheaders
| select column0 column2
| rename date temperature
| upsert date {|l| $l.date | format date "%B"}
| chunk-by {$in.date}
| nuplot boxplot --xaxis date --title "Average monthly temperatures for 2024 in Berlin"
