[3.0.0] - 2021-06-04

Added

• In tooltip customization API:

  • layerTooltips(variables) - the new parameter variables defines a list of variable names, which values will be
    placed in the general multiline tooltip.
    See: Tooltip Customization.

• lets-plot-mini-apps GitHub repository containing examples of using
  the Lets-Plot Kotlin API in JVM and Kotlin-JS projects.

Changed

• [BREAKING CHANGE]: The CDN for delivering the Lets-Plot JavaScript library is
  now JSDELIVR
  (was CDNJS).

  New URLs:

  • Lets-Plot v2.0.3: https://cdn.jsdelivr.net/gh/JetBrains/lets-plot@v2.0.3/js-package/distr/lets-plot.min.js
  • The latest version: https://cdn.jsdelivr.net/gh/JetBrains/lets-plot/js-package/distr/lets-plot.min.js

• The project has been converted to a "multiplatform" project targeting JVM and JS platforms.

  To use Lets-Plot Kotlin API in your project, include dependencies:

  • JVM: implementation "org.jetbrains.lets-plot:lets-plot-kotlin-jvm:3.0.0"
  • JS: implementation "org.jetbrains.lets-plot:lets-plot-kotlin-js:3.0.0"

  See README_DEV.md for more details.

• [BREAKING CHANGE] The JVM artifact lets-plot-kotlin-api is no longer deployed: replaced with the
  equivalent lets-plot-kotlin-jvm.

• The artifact lets-plot-kotlin-api-kernel renamed to lets-plot-kotlin-kernel (this change only concerns Kotlin
  Jupyter Kernel)

Fixed

• Poor font rendering in Swing/Batik. Related to: [#364]
• Exclude slf4j implementation from lets-plot-common [#374]
• geom_boxplot: should be possible to create boxplot without specifying
  x-series [#325]
• geom_hline: graph plotted outside of coordinate plane visible
  part [#334]
• Draw geometry only once if layer has no aes mapping
  specified [#73]
• Can't build plot: "Uncaught SyntaxError: Unexpected string" in a
  console [#371]

[2.0.1] - 2021-04-19

  Demo: Formatting demo

  See also: Formatting

• The guides() function [#52].
