迷你图

一个小型、简单的图表，没有轴或坐标，显示数据变化的大致形状，通常与文本内联使用或用于小空间。

"use client"

import { Chart, useChart } from "@chakra-ui/charts"
import { Area, AreaChart } from "recharts"

const Demo = () => {
  const chart = useChart({
    data: [
      { value: 10 },
      { value: 16 },
      { value: 19 },
      { value: 15 },
      { value: 12 },
      { value: 15 },
      { value: 10 },
      { value: 18 },
    ],
    series: [{ name: "value", color: "teal.solid" }],
  })

  return (
    <Chart.Root width="28" height="12" chart={chart}>
      <AreaChart data={chart.data}>
        {chart.series.map((item) => (
          <Area
            key={item.name}
            isAnimationActive={false}
            dataKey={chart.key(item.name)}
            fill={chart.color(item.color)}
            fillOpacity={0.2}
            stroke={chart.color(item.color)}
            strokeWidth={2}
          />
        ))}
      </AreaChart>

示例

¥Examples

柱状图

¥Bar Chart

迷你图可以用柱状图制作。

¥Sparklines can be made with bar charts.

"use client"

import { Chart, useChart } from "@chakra-ui/charts"
import { Bar, BarChart, Cell } from "recharts"

const Demo = () => {
  const chart = useChart({
    data: [
      { value: 10, fill: "teal.solid" },
      { value: 16, fill: "green.solid" },
      { value: 19, fill: "teal.solid" },
      { value: 15, fill: "green.solid" },
      { value: 12, fill: "teal.solid" },
      { value: 15, fill: "teal.solid" },
      { value: 10, fill: "teal.solid" },
      { value: 18, fill: "teal.solid" },
    ],
  })

  return (
    <Chart.Root width="28" height="12" chart={chart}>
      <BarChart data={chart.data} barSize={8}>
        <Bar
          isAnimationActive={false}
          dataKey={chart.key("value")}
          fill={chart.color("teal.solid")}
          stroke=""
        >
          {chart.data.map((item) => (
            <Cell key={item.value} fill={chart.color(item.fill)} />
          ))}
        </Bar>
      </BarChart>
    </Chart.Root>
  )
}

折线图

¥Line Chart

迷你图也可以用折线图制作。

¥Sparklines can also be made with line charts.

"use client"

import { Chart, useChart } from "@chakra-ui/charts"
import { Line, LineChart } from "recharts"

const Demo = () => {
  const chart = useChart({
    data: [
      { value: 10 },
      { value: 16 },
      { value: 19 },
      { value: 15 },
      { value: 12 },
      { value: 15 },
      { value: 10 },
      { value: 18 },
    ],
    series: [{ name: "value", color: "teal.solid" }],
  })

  return (
    <Chart.Root width="28" height="12" chart={chart}>
      <LineChart data={chart.data}>
        {chart.series.map((item) => (
          <Line
            key={item.name}
            isAnimationActive={false}
            dataKey={chart.key(item.name)}
            stroke={chart.color(item.color)}
            strokeWidth={2}
            dot={false}
          />
        ))}
      </LineChart>
    </Chart.Root>
  )
}

参考

¥Reference

要在迷你图上引用特定值，请使用 recharts 中的 Reference 组件。

¥To reference a specific value on the sparkline, use the Reference component from recharts.

"use client"

import { Chart, useChart } from "@chakra-ui/charts"

const Demo = () => {
  const chart = useChart({

      { value: 19 },
      { value: 15 },
      { value: 12 },
      { value: 15 },
      { value: 10 },
      { value: 18 },
    ],
    series: [{ name: "value", color: "teal.solid" }],
  })

  return (
    <Chart.Root maxW="200px" chart={chart}>
      <LineChart data={chart.data}>
        {chart.series.map((item) => (
          <Line
