Column Chart

Component

About

A grouped vertical bar chart that plots up to three numeric series using fill patterns (solid, striped, outline) instead of color, with an optional baseline axis, category labels, legend and median/average reference line, designed for low-contrast e-ink style displays.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Column Chart to your project and fits it to your theme.

Code

How Column Chart is used: the demo's code. The component's own source comes with a free account.
