v0.2.0

[0.2.0] - 2026-10-20

Added

• CHANGELOG.md, a release badge and a pinned-version install command in the README.

Changed

• Breaking: colormap is now written out in names: colors_from_cmap →
  colors_from_colormap, style_diverging_cmap → style_diverging_colormap, and in
  a style's colors.py DEFAULT_CMAP → DEFAULT_COLORMAP, DIVERGING_CMAP →
  DIVERGING_COLORMAP. The example example_colors_from_cmap.py is now
  example_colors_from_colormap.py. Keyword arguments keep matplotlib's cmap=.
• The version now lives only in src/cjcplot/__init__.py; pyproject.toml reads it from there.
• README: example images centred one per row, in a new order; the figure-size
  section now covers LaTeX, Word, PowerPoint and other documents; the quick
  start passes x_data= and y_data= and explains how to switch to your own
  style.
• Tests: every test has a docstring, and non-obvious lines a comment.
• Fuller explanations of the per-trace helpers and POINTS_PER_INCH in _figure.py.
• The histogram example uses more samples and finer bins, so it looks smooth.
• AGENTS.md: rules for keeping tests, docs and this changelog up to date.

Fixed

• Type hints for xlim/ylim and legend_loc now match matplotlib's, so editors
  such as PyCharm no longer warn; legend_loc also autocompletes its allowed values.
• The same for histtype in plot_histogram_1d and shading in plot_2d.

v0.1.0

[0.1.0] - 2026-10-16

First release.

Added

• plot_1d, plot_histogram_1d and plot_2d, sized as fractions of a
  document's text width; plot_3d as a placeholder.
• Switchable styles (use_style, available_styles, style_colors), with the
  bundled cjc style applied on import.
• cjc colormaps: reds_cjc, blues_cjc, bluered_cjc (diverging), and
  blueyellow_cjc, yellowblue_cjc, yellowred_cjc, redyellow_cjc.
• colors_from_cmap to sample line colours from a colormap.
• Colormap tools: truncate_colormap, colormap_from_colors,
  join_colormaps, register_colormap.
• Tests, examples and a GitHub Actions workflow.
