Changelog

0.1.1

Backward-compatible additions; existing calls and output are unchanged.

decorate_genome_axis gains mb_ticks / mb_tick_step: label x in Mb every mb_tick_step bp within each chromosome (reset per chromosome), with chromosome names drawn as compact off-axis text - the denser mode for genome-wide scatter QC. Plumbed through plot_scatter_1d, plot_scatter_1d_multisample, plot_heatmap, and plot_heatmap_cnp. Default off, 50Mb step; the Mb labels are rotated by rotation (default 60 degrees) so the dense ticks do not overlap.
Version lives in the repo-root VERSION file: pyproject.toml builds from it (dynamic version = {file = "VERSION"}) and cnplot.__version__ reads it back, falling back to the installed metadata outside a source checkout. One edit per bump.
GenomeAxis(region_bed=None): build one full-length region per chromosome from chrom_sizes, i.e. a plain whole-genome axis with no gaps, for callers that only have a sizes file.

First release of cnplot, the shared copy-number plotting library.

GenomeAxis: a genome coordinate transform built from a region BED and chromosome sizes, mapping any bin table by (#CHR, START, END).
Colormaps: get_cn_cmap, get_ascn_cmap, get_baf_cmap, get_log2rdr_cmap, get_mixcn_cmap, get_multiclass_cmap, set_palette.
Integer copy-number profiles: plot_cnv_profile over the seg.ucn table.
1D genome scatter: plot_scatter_1d and the plot_scatter_1d_multisample builder, with hue/palette and an optional expected_df overlay.
2D RDR/BAF scatter: plot_scatter_2d (seaborn JointGrid) with copy-number landmarks.
Single-cell heatmap: plot_heatmap / plot_heatmap_cnp with ordered categorical and posterior side strips and an optional value colorbar.
