Tooltip - Advanced
A React chart with advanced tooltip formatter showing custom styling, units, and calculated totals using shadcn/ui and Recharts
Default tooltips show values, but what about units, totals, or context? This React bar chart uses ChartTooltipContent's formatter prop to customize tooltip display with units (kcal), tabular number styling, and calculated totals at the bottom. Built with shadcn/ui and Recharts, the formatter function receives value, name, item, and index—letting you render custom JSX for each series. Add borders for totals, inject units, style with monospace fonts—complete control over tooltip appearance. Perfect for financial dashboards (currency symbols), fitness apps (unit labels), or analytics showing derived metrics alongside raw values.
