import { Line, LineChart, XAxis, YAxis, CartesianGrid, ReferenceLine } from "recharts"
import { ChartContainer, ChartTooltip, ChartTooltipContent } from "@/components/ui/chart"

<ChartContainer config={chartConfig} className="min-h-[300px]">
  <LineChart data={data}>
    <CartesianGrid strokeDasharray="3 3" vertical={false} />
    <XAxis dataKey="time" />
    <YAxis />
    <ChartTooltip content={<ChartTooltipContent />} />
    <Line
      type="monotone"       {/* or "linear", "step" */}
