Every value below is provisional: an initial project choice, not a journal or conference requirement. Change one, re-run, and compare the pictures.

Environment: matplotlib 3.11.1, Python 3.12.13.

The PNGs below are 300 DPI previews, so on screen they are roughly four times the printed size. Judge legibility accordingly, or open the PDF at 100%.

bar-positive

All-positive bars: they sit exactly on the baseline, one colour for the one series, bar width and category label spacing.

Checks: 14 pass, 0 warn, 0 fail, 1 not checked (visual_review is always the last of those — no script can close it).

Spec: tests/data/bar-positive.json · PDF: bar-positive/figure.pdf · Report: bar-positive/report.json

bar-signed

Bars crossing zero: the zero line, symmetric padding, and a zero-valued category that must still be visible as a category.

Checks: 14 pass, 0 warn, 0 fail, 1 not checked (visual_review is always the last of those — no script can close it).

Spec: tests/data/bar-signed.json · PDF: bar-signed/figure.pdf · Report: bar-signed/report.json

line-many

Eight series: colours 1-6, then colours 1-2 again with the dash pattern taking over. Check that series 7 and 8 stay separable from 1 and 2.

Checks: 14 pass, 0 warn, 0 fail, 1 not checked (visual_review is always the last of those — no script can close it).

Spec: tests/data/line-many.json · PDF: line-many/figure.pdf · Report: line-many/report.json

line-mathtext

Mathtext labels and legend entries. Variables italic, units upright, no LaTeX installation involved.

Checks: 14 pass, 0 warn, 0 fail, 1 not checked (visual_review is always the last of those — no script can close it).

Spec: tests/data/line-mathtext.json · PDF: line-mathtext/figure.pdf · Report: line-mathtext/report.json

line-multi

Three series: the first three palette colours, their bound marker shapes, and legend placement and size.

Checks: 14 pass, 0 warn, 0 fail, 1 not checked (visual_review is always the last of those — no script can close it).

Spec: tests/data/line-multi.json · PDF: line-multi/figure.pdf · Report: line-multi/report.json

line-single

One series: line width, marker size and spacing, tick and axis-label sizes. No legend, because a single series names itself in the y label.

Checks: 14 pass, 0 warn, 0 fail, 1 not checked (visual_review is always the last of those — no script can close it).
