How do I create a 时间线 chart in JavaScript?

Install with `npm install katucharts.js`, then call KatuCharts.chart(container, { chart: { type: 'timeline' }, series: [...] }).

Why does my 时间线 chart render as a line chart?

The chart type was not registered. KatuCharts logs "KatuCharts: unknown series type " ", falling back to line" and draws a line chart rather than throwing. Import the module the type belongs to — for example `import 'katucharts.js/bio';` — before creating the chart.

Why do I get "Cannot read properties of null (reading 'appendChild')"?

The container element does not exist when the chart is created. Create the chart after the element is in the DOM: in React that means inside useEffect, not during render.

Why is the chart rendering with zero height?

The container has no height. A div with no content collapses to zero. Give it a height in CSS, or pass `chart: { height: 400 }` in the options.

时间线

type: 'timeline'

沿一条线排列的顺序事件标记；每个点都是一个里程碑，包含名称、简短标签和可选的描述（显示在提示框中）。默认水平，设置 chart.inverted 时为垂直。

数据结构

传入图表的 JSON——可直接放进你的 series。

data: [
  { name: 'Founded', label: '2019', description: 'First prototype shipped.' },
  { name: 'Series A', label: '2022', description: '$15M raised; team of 40.' },
  { name: 'v1.0', label: '2024', description: 'General availability launch.' }
]

示例

import KatuCharts from 'katucharts.js';

KatuCharts.chart('container', {
  chart: { type: 'timeline' },
  series: [{
    data: [
      { name: 'Founded', label: '2019', description: 'First prototype shipped.' },
      { name: 'Series A', label: '2022', description: '$15M raised; team of 40.' },
      { name: 'v1.0', label: '2024', description: 'General availability launch.' }
    ]
  }]
});

类型特定选项

选项	描述
`dataLabels.format`	每个点的标签模板，例如 '<b>{point.name}</b><br>{point.label}'。
`dataLabels.alternate`	在线条两侧交错显示标签（默认 true）。
`dataLabels.distance`	标记与其标签之间的间距（默认 22）。
`chart.inverted`	将时间线纵向排列而非横向。
`marker`	每个点的标记 — { symbol, radius, lineColor, lineWidth }。
`colorByPoint`	从调色板为每个标记着色（默认 true）。

变体

垂直（反转）

设置 chart.inverted 可将时间线纵向排列——非常适合窄列和学历背景展示。

KatuCharts.chart('container', {
  chart: { type: 'timeline', inverted: true },
  series: [{
    data: [
      { name: "Bachelor's", label: '2006 – 2008', description: 'Computer Networks — FAZ, Brazil' },
      { name: "Master's", label: '2014 – 2016', description: 'Computer Science — UFPA, Brazil' },
      { name: 'Doctorate', label: '2018 – 2022', description: 'Artificial Intelligence — USP, Brazil' }
    ]
  }]
});

提示框中的描述

为每个点提供描述，悬停时会显示在提示框中，从而保持图表上的标签简短。

KatuCharts.chart('container', {
  chart: { type: 'timeline' },
  tooltip: { pointFormat: '{point.description}' },
  series: [{
    data: [
      { name: 'Founded', label: '2019', description: 'First prototype shipped.' },
      { name: 'Series A', label: '2022', description: '$15M raised; team of 40.' },
      { name: 'v1.0', label: '2024', description: 'General availability launch.' }
    ]
  }]
});

单侧标签

将 dataLabels.alternate 设为 false，让所有标签都位于线条的同一侧。

KatuCharts.chart('container', {
  chart: { type: 'timeline' },
  series: [{
    dataLabels: { alternate: false },
    data: [
      { name: 'v1.0', label: '1月' },
      { name: 'v1.5', label: '4月' },
      { name: 'v2.0', label: '8月' },
      { name: 'v2.4', label: '11月' }
    ]
  }]
});

纯文本标签（圆形标记）

将 dataLabels.borderWidth 设为 0 即可去掉方框，让更大的圆形标记承载时间线。

KatuCharts.chart('container', {
  chart: { type: 'timeline' },
  series: [{
    marker: { radius: 9 },
    dataLabels: { borderWidth: 0 },
    data: [
      { name: 'Discovery', label: '一季度' },
      { name: '设计', label: '二季度' },
      { name: 'Build', label: '三季度' },
      { name: 'Launch', label: '四季度' }
    ]
  }]
});

Common errors

Why does my 时间线 chart render as a line chart?: The chart type was not registered. KatuCharts logs "KatuCharts: unknown series type "<type>", falling back to line" and draws a line chart rather than throwing. Import the module the type belongs to — for example `import 'katucharts.js/bio';` — before creating the chart.
Why do I get "Cannot read properties of null (reading 'appendChild')"?: The container element does not exist when the chart is created. Create the chart after the element is in the DOM: in React that means inside useEffect, not during render.
Why is the chart rendering with zero height?: The container has no height. A div with no content collapses to zero. Give it a height in CSS, or pass `chart: { height: 400 }` in the options.
