Label Configuration

LabelList component with top positioning and styling:

<Bar dataKey="desktop" fill="var(--color-desktop)" radius={8}>
  <LabelList
    position="top"
    offset={12}
    className="fill-foreground"
    fontSize={12}
  />
</Bar>

Chart Margins

Adjusted margins to accommodate top labels:

<BarChart
  accessibilityLayer
  data={chartData}
  margin={{
    top: 20,
  }}
>

Label Properties

  • Position: top - Labels appear above bars
  • Offset: 12 - 12px spacing between bar and label
  • Styling: fill-foreground - Uses theme foreground color
  • Font Size: 12 - Compact readable text size

Implementation Notes

  • Top margin increased to 20px to prevent label clipping
  • Labels automatically display data values from the bar's dataKey
  • LabelList inherits data from parent Bar component
  • Font size optimized for readability without overwhelming the chart
  • Offset provides comfortable spacing between bars and labels
  • Perfect for applications requiring immediate access to exact data values alongside visual representation
