Tooltip - Formatter
A React chart with custom tooltip formatter for value and label formatting using shadcn/ui and Recharts
Need to add units or custom styling to tooltip values without building complex layouts? This React bar chart uses ChartTooltipContent's formatter prop with a simpler approach than advanced patterns—just format each value's display with units (kcal), custom styling, and layout control. Built with shadcn/ui and Recharts, the formatter receives value and name, returns custom JSX for each series. Add currency symbols, percentage signs, or unit labels while keeping the default tooltip structure. Perfect for dashboards needing formatted numbers (currency, percentages), metrics with units (km, hrs, GB), or custom text styling without rebuilding entire tooltip layouts.
