Theme Gallery¶

This gallery renders the same suite of example charts — the basic chart types plus research-style figures — under each of the six predefined themes, composed into one grid per chart group so the whole suite is visible at a glance. The groups follow the charts index — trends and comparisons, distributions, relationships, composition — so each tile sits next to the guide that documents it. The available themes are:

Theme	Character
THEME.DEFAULT	Tableau-style categorical palette, open spines, soft grid.
THEME.GREYSCALE	Monochrome, print-friendly.
THEME.INK	Diversified YlGnBu palette with navy ink accents.
THEME.MINIMAL	Accent blue with deep grays, no spines, flat bars.
THEME.MATERIAL	Google palette, bottom spine only, light grid.
THEME.HATCH	Hatch cycle, black edges, dotted grid, value labels.

Themes also carry defaults for chart settings: every theme shows a muted y-grid unless a chart call sets show_grid itself, MINIMAL, MATERIAL, and HATCH label bar values by default, and HATCH hatches bar series via its hatch cycle — which is why the very same chart code below renders with grids, value labels, and hatches that differ per theme. An explicit setting always wins.

The small-multiples example is itself a Grid; grid figures nest inside Grid, so it takes one cell of each theme's composition grid.

The sample data shared by every theme suite is defined in a hidden cell.

The whole suite is built by one function (in a hidden cell), so every theme renders the exact same chart code — grids, value labels, and hatches come from the theme's own defaults. pair supplies the two accent colors used where a chart styles lines explicitly (trend/forecast/walk examples). Intermediate figures that only exist to feed a Panel are closed as we go, so only the group grids are displayed. The small-multiples Grid nests as one composition cell and rebuilds its own layout there; the nested charts on the block's edges keep their y-axes inline with the gallery column's axes.

Hatch¶

Black edges, dotted grid — and the hatch cycle ("", "//", "..") applied per bar series, so grouped bars stay distinguishable in black-and-white print.

Applying a theme replaces the whole global configuration, so remember to call config.set_theme(...) (or config.reset_config()) before building the charts it should style. See the themes how-to for customizing themes attribute by attribute.
