With version 0.5.0, we are introducing several major improvements including:

datetime support for time series plotting,
relative sizing for diagrams,
and significant performance improvements through integration with the package Komet.

Changelog

Additions

Added comprehensive datetime support for time series plotting with customizable formatting.
Diagrams now support relative and ratio inputs for diagram.width and diagram.height.
The parameter bar.offset now accepts array arguments for variable offsets.
In addition to coordinate arrays, functions x => f(x) can now be used as $y$ arguments in plot, bar, stem, and fill-between (thanks to @xkevio).
Column headers in text files can now be used as converter names in load-txt (thanks to @timfi).
Added parameter colormesh.excess to allow masking all values that are out-of-bounds.

Improvements

Major Performance Boost:
- Contour computations are now significantly faster through Komet integration.
- Boxplots can now be computed for considerably larger data sets thanks to using the Komet plugin.
tick-locate.linear now supports constrained tick distances like tick-distance: (min: 1).
⚠️ The default for label.angle is now auto which results in 0° for x-labels and -90° for y-labels. With this change, the angle can now be changed with a conditional show rule (before, this was not possible since the -90° was hard-coded into the y-label).
⚠️ Improved the schoolbook theme.
Updated elembic from version 1.1.0 to 1.1.1.
Updated Zero from version 0.4.0 to 0.5.0.

Fixes

Corrected colormesh positioning in zoomed-in views.
Fixed label space computation when using show rules.
Resolved issues with subtick labels and axis attachments.
Corrected axis positions defined in terms of data coordinates along the other axis when using top or right alignment.
Fixed a regression with setting label.pad to none.
Resolved placement of extra subticks.
