# nuplot
`nuplot` is a [nushell](https://www.nushell.sh) plugin for plotting charts. It
builds interactive charts from your data that are opened inside the web browser.
```shell
go install github.com/gtnebel/nu_plugin_nuplot@latest
```
## Compatibility matrix
Nushell plugins always have to be built for a specific nushell version. This
table shows which `nuplot` releases are compatible to which `nushell` version.
| nuplot version | nushell version |
| ------------------------------------------------------------------------ | --------------- |
| [0.1.0](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.1.0) | 0.104.0 |
| [0.1.1](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.1.1) | 0.105.0 |
| [0.1.2](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.1.2) | 0.106.0 |
| [0.1.3](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.1.3) | 0.107.0 |
| [0.2.0](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.2.0) | 0.107.0 |
| [0.2.1](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.2.1) | 0.108.0 |
| [0.2.2](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.2.1) | 0.109.0 |
| [0.2.3](https://github.com/gtnebel/nu_plugin_nuplot/releases/tag/v0.2.1) | 0.110.0 |
## 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
```nushell
{'apples': 7 'oranges': 5 'bananas': 3} | nuplot pie --title "Fruits"
```
#### Show weather forcast from wttr.in as bar chart
```nushell
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
```nushell
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"
```
## Getting binaries
Binaries for a range of operating systems and architectures are provided with
each release on GitHub. Simply download the zip file for your os and
architecture.
## Install with `go install`
The binary is installed to `$GOPATH/bin` (`~/go/bin`)
```shell
go install github.com/gtnebel/nu_plugin_nuplot@latest
```
## Build from source
**Prerequisits:** You will need the Go compiler to build the project.
Check out the project
```sh
git clone https://github.com/gtnebel/nu_plugin_nuplot.git
```
Build the project
```sh
go build
```
## Register the plugin an nushell
Use the `plugin add` and `plugin use` commands to register and use the plugin.
The `plugin use` command is only needed to activate the newly added plugin in
the currently running shell.
**IMPORTANT:** The path to `nu_plugin_nuplot` has to be in `$PATH` if you run
the code below. If you installed the plugin using `go install`, add `~/go/bin`
to your `$PATH`.
```nu
plugin add (which nu_plugin_nuplot | get 0.path)
plugin use nuplot
```
Now, `help nuplot line` should show the help for the line chart.
