lets-plot 4.10.1

An open source library for statistical plotting

Lets-Plot

Lets-Plot is a multiplatform plotting library built on the principles of the Grammar of Graphics.

The library design is heavily influenced by Leland Wilkinson's work 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.

"Lets-Plot in SciView" plugin

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

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 4.10.0

• ggdeck()

  The new ggdeck() function overlays multiple independent plots in a shared plotting area. Typically, all plots share one axis — enabling dual-axis charts and multivariate comparisons.
  
  

  • Dual Axis:

    

    See: example notebook.
    
    

  • Multivariate Comparison:

    

    See example notebook.

• Alpha Channel in Color Strings

  • Named colors accept an opacity suffix after a slash: "steelblue/0.35".
  • Hex colors accept an alpha channel: #RRGGBBAA or short form #RGBA.
  

  See: example notebook.

• Text Angle in Facet Strip Labels

  Facet strip labels can now be rotated via the angle parameter of element_text(), applied to strip_text, strip_text_x, or strip_text_y.

  Thanks to a contribution by tentrillion.
