Feature Gallery#
A visual index of what skyplothelper draws. Click any figure for a page with the full example code. Figures follow the site’s light/dark mode by default — the plot-colors button in the top bar (next to the site theme toggle) overrides them independently, e.g. to preview publication-style light figures while reading in dark mode.
