v4.5.2

[4.5.2] - 2024-12-13

Changed

• Number formatting:
  • We have aligned our specifications with D3.js (rather than Python): g format type with ~ (e.g. ~g) now truncates trailing zeros, and without ~ it doesn't.
  • The default number formatter now respects theme(exponent_format=...) settings and does not use 's' format type for large numbers.
• Legends with more than 200 items are now not rendered.

Fixed

• Bad precision in the default tooltip format when using coord limits [#1134].
• Display integer values without fractional part in tooltips [#1186].
• Suboptimal tooltip positioning in facets [#1187].
• Incorrect Y-axis layout with facets and panel_inset [#1194].
• Grouped plot hits the limit of 1000 and doesn't render with not-friendly exception [#1224].

• lets_plot_kotlin_bridge is unable to locate libc++.1.dylib, I am using Mac m2 [#1234].
• Wrong formatting when type='g' for small values [#1238].
• Formatting when type='g' for large values throws exception [#1239].
• Wrong formatting when type='s' with explicit precision [#1240].
• Extra trim in formatted number when type='g' [#1241].
• Axis breaks are badly formatted if explicitly set [#1245].
• Badly formatted zero break for the "~g" format [#1246].
• How to adjust the vertical position of geom_text when using position_dodge [#1248].
• Incorrect result for format(9.999, ".2f") [#1251].
• Tooltips overlapping when not enough vertical space for them [#1254].
• Plot limited to 1000 lines (Internal error: IllegalStateException : Too many groups: 1099) [#1261].
• Nice to have tooltip to inherit formatting configured for axis [LPK-229].

v4.5.1

Changed

• Interact refinement:
  • Dragging the plot or Livemap disables the pinned tooltip mode.
  • Double-clicking the plot or Livemap disables the pinned tooltip mode.
  • Ctrl + double-clicking the Livemap zooms in without the blinking fade-in effect.

Fixed

• Buttons alignment in the toolbar.

• [BREAKING] For API deprecated in v4.0 the deprecation level raised to "Error" (only relevant for Kotlin clients).

• [BREAKING] The 'base-midnight', 'base-antique' and 'base-flatblue' tilesets are deprecated (no longer served by CARTO) and will be removed in future releases.

Fixed

• Support layering aes() multiple times [#822].
• waterfall_plot: faceting doesn't work without a measure mapping [#1152].

• Legend icon background is not transparent when legend_background is set to "blank" in theme [#1167].
• Unable to display or save graph when using geom_path [#1168].
• Legend icon background should inherit the fill color of the plot panel (i.e. grey when theme_grey is used).
