v2.2.0

[2.2.0] - 2021-10-29

Added

• coord_flip().

  See: example notebook.

• Date-time formatting support:

  • tooltip format() should understand date-time format pattern [#387];
  • scale_x_datetime should apply date-time formatting to the breaks [#392].

  See: example notebook.

• Pre-configured themes:

  • Standard ggplot2 themes: theme_grey(), theme_light(), theme_classic(), theme_minimal();
  • Other themes: theme_minimal2() - the default theme, theme_none().

• Theme modification: more parameters were added the theme() function.

  See: example notebook.

Note: fonts size, family and face still can not be configured.

• corr_plot() function now also accepts pre-computed correlation coefficients. I.e. the following two expressions are equivalent:

    corr_plot(iris_df).points().labels().build()
    corr_plot(iris_df.corr()).points().labels().build()  # new

Changed

• The size of fonts on plot was slightly increased all across the board.
• The default plot size was increased by 20%, it's now 600x400 px.
• Deprecated API: stat_corr() and "correlation stat" will be removed in one of the future releases.
  Please use the corr_plot() plot builder object instead.

Fixed

• Ordering facets - the "order" value 0 disables facet ordering [#454].
• Tooltips for discrete variables: add the dependence of the tooltip on the number of factors.
  The X-axis tooltip is always shown for discrete data.
• map_join doesn't work when join variables with same names without mappings [#428].
• Zoom without clipping breaks tooltips [#373].
• Unreadable breaks on axis [#430].
• Map rendering is broken when browser uses scaling [#450].
• corr_plot() error for data with zero variation [#329].
• Misleading error message [#271].

v2.1.0

[2.1.0] - 2021-08-16

Added

• Ordering categories. New parameters in the as_discrete function:

  • order_by (string) - the name of the variable by which the ordering will be performed;
  • order (int) - the ordering direction - 1 for ascending direction and -1 for descending (default value).

  See: as_discrete.

• Basemap tiles configuring:

  • Subdomains parameter {s} for XYZ raster tiles.
  • Solid color tiles: maptiles_solid().
  • Builtin configurations for some 3rd party maptile services. The lets_plot.tilesets module.

  See: Configuring basemap tiles.

Changed

• Upgraded Apach Batik version to 1.14 (was 1.12) [#398].
• Upgraded Kotlin version to 1.5.21 (was 1.4.21)
• Upgraded Gradle version to 7.1.1 (was 6.8.3)

Fixed

• geom_livemap: properly handle max_zoom pamareter in maptiles_zxy().
• Strange looking legend for tiles [#245].
• Need to skip "bad" values during scale transformation [#301].
• NPE on negative value in data and scale_xxx(trans='log10') [#292].
• Legend is broken when using scale_fill_brewer with 'trans' parameter [#284].
• Scale breaks should be distributed evenly on 'sqrt' scale. [#407].
• Wrong tooltip formatting when used with log10 scales [#406].
• Bad axis labels when using both plot and layer data [#327].
• Plot layout looks wrong [#403].
• map_join is not working correctly when map=geocoder [#380]
• Tooltip default formatting should not change after adding other variables to tooltip [#388].
• Tooltip on axis: increase the font size. [#399].
• Tooltip format for variable is not working [#401].
• Wrong direction in colorbars (legend) [#204].
• geom_jitter: show axis tooltips (same as geom_point) [#412].
• Outlier tooltips: the spout sometime is too long (boxplot) [#358].
• Faceted plot is broken by geom with "constant" aesthetics [#391].
• Interactive maps in AWT (PyCharm plugin):
  • A memory leak in PyCharm caused by a final void dispose() method in PlotPanel.
  • When showing map in PyCharm CPU is busy all the time, even then nothing is changing on screen.
  • Click events detection.

[2.0.4] - 2021-06-09

Changed

• Upgraded kotlinx.html version to 0.7.3 (was 0.7.2)

In JVM projects it's no longer necessary to add https://maven.pkg.jetbrains.space/public/p/kotlinx-html/maven repository

• Multilayer plots are corrupted [#385].

v2.0.3

[2.0.3] - 2021-06-02

https://cdn.jsdelivr.net/gh/JetBrains/lets-plot@v2.0.3/js-package/distr/lets-plot.min.js

Fixed

• Removed the last dependency on bintray JCenter (commit).
• 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]
• map: calif.housing [#140]
• Can't build plot: "Uncaught SyntaxError: Unexpected string" in a console [#371]
• All scales should have the 'format' parameter [#347].
