# Lets-Plot

[![official JetBrains project](http://jb.gg/badges/official-flat-square.svg)](https://confluence.jetbrains.com/display/ALL/JetBrains+on+GitHub)
[![License MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://raw.githubusercontent.com/JetBrains/lets-plot-kotlin/master/LICENSE)

**Lets-Plot** is a multiplatform plotting library based on the Grammar of Graphics. 

The library' design is heavily influenced by Leland Wilkinson work [The Grammar of Graphics](https://www.goodreads.com/book/show/2549408.The_Grammar_of_Graphics) describing the deep features that underlie all statistical graphics.

> This grammar [...] is made up of a set of independent components that can be composed in many different ways. This makes [it] very powerful because you are not limited to a set of pre-specified graphics, but you can create new graphics that are precisely tailored for your problem.
> - Hadley Wickham, "[ggplot2: Elegant Graphics for Data Analysis](https://ggplot2-book.org/index.html)"

We provide ggplot2-like plotting API for Python and Kotlin users. 


## Lets-Plot for Python [![Latest Release](https://badge.fury.io/py/lets-plot.svg)](https://pypi.org/project/lets-plot)

A bridge between R (ggplot2) and Python data visualization. \
To learn more see the documentation site at [lets-plot.org](https://lets-plot.org).          


## Lets-Plot Kotlin API [![Latest Release](https://img.shields.io/github/v/release/JetBrains/lets-plot-kotlin)](https://github.com/JetBrains/lets-plot-kotlin/releases/latest)

*Scientific mode* in PyCharm and in IntelliJ IDEA provides support for interactive scientific computing and data visualization.

[*Lets-Plot in SciView*](https://plugins.jetbrains.com/plugin/14379-lets-plot-in-sciview) plugin adds 
support for interactive plotting to IntelliJ-based IDEs with the *Scientific mode* enabled.
 
>
> **Note:** The *Scientific mode* is NOT available in communinty editions of JetBrains IDEs.

## What is new in 4.2.0

- #### Support for `"Categoricals"`

  See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/factor_levels.ipynb).

- #### Superscript for Numbers in Scientific Notation

  > #### Warning!
  >
  > Do NOT(!) use `exponent_format='pow'` if you are planning to export plot to a raster format (PNG,PDF).
  >
  > The `CairoSVG` library (which is under the hood of our `ggsave()` function) does not handre `tspan` element properly end breaks superscript notation when transforming SVG to PNG/PDF.
  >
  > More details: https://github.com/Kozea/CairoSVG/issues/317

  See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/superscript_exponent.ipynb).

- #### Exporting Plot to a File-Like Object. <br>
  Convenience methods: `to_svg()`, `to_html()`, `to_png()`, `to_pdf()`

  See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/new_export_methods.ipynb).

- #### Sharing of X,Y-scale Limits Between Subplots in `gggrid()`

  See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/gggrid_scale_share.ipynb).

- #### `geom_spoke()`

  See: [example notebook](https://nbviewer.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/geom_spoke.ipynb).

- #### High-contrast Tileset "BW" for `geom_livemap()`

  <br>

  See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/geom_livemap_bw_tiles.ipynb).<br>
  See Advanced EDA example: [Spatial prediction of soil pollutants with multi-output Gaussian processes](https://nextjournal.com/asmirnov-horis/spatial-prediction-of-soil-pollutants-with-multi-output-gaussian-processes?token=26GT2sBa3Ycw6LGZxqdTay).
                                          
- #### Other New Features and Improvements

  - `scale_x_log2()`, `scale_y_log2()`
  - New variables computed by `'count'` and `'count2d'` statistics: `'..sumprop..'`, `'..sumpct..'`.
    See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/new_stat_count_vars.ipynb).
  - Support using dictionaries for breaks/labels/values customization in `scale_xxx()` functions.
    See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/scale_params_with_dict.ipynb).
  - The `lablim` parameter in `scale_xxx()` functions.
    See: [example notebook](https://nbviewer.jupyter.org/github/JetBrains/lets-plot/blob/master/docs/f-23f/scale_lablim.ipynb).
