Timing bar

Horizontal request-phase waterfall, one segment per phase.

Basic usage

Data comes in via props; rendered as pure SVG with no third-party charting dependency. Colors come from the --viz-1..8 tokens, colorblind-friendly.

背景

<script setup lang="ts">
import { CfTimingBar } from '@chufix-design/vue';
const phases = [
  { label: 'DNS', start: 0, end: 12, colorIndex: 6 },
  { label: 'Connect', start: 12, end: 38, colorIndex: 0 },
  { label: 'TLS', start: 38, end: 92, colorIndex: 2 },
  { label: 'TTFB', start: 92, end: 245, colorIndex: 1 },
  { label: 'Download', start: 245, end: 312, colorIndex: 3 },
];
</script>

<template>
  <CfTimingBar :phases="phases" />
</template>

<CfTimingBar ... />

Real waterfall scenario

Three concurrent HTTP requests with their timings stitched together: DNS / Connect / TLS / Wait / Receive each in its own color.

背景

GET /v1/me · 264ms

GET /v1/orders (cached) · 220ms

POST /v1/charges · 480ms

<script setup lang="ts">
import { CfTimingBar } from '@chufix-design/vue';
// 真实场景：3 个并发 HTTP 请求
const r1 = [
  { label: 'DNS', start: 0, end: 8, colorIndex: 6 },
  { label: 'Connect', start: 8, end: 32, colorIndex: 0 },
  { label: 'TLS', start: 32, end: 80, colorIndex: 2 },
  { label: 'Wait', start: 80, end: 220, colorIndex: 1 },
  { label: 'Receive', start: 220, end: 264, colorIndex: 3 },
];
const r2 = [
  { label: 'Wait', start: 0, end: 184, colorIndex: 1 },
  { label: 'Receive', start: 184, end: 220, colorIndex: 3 },
];
const r3 = [
  { label: 'Wait', start: 0, end: 412, colorIndex: 5 },
  { label: 'Receive', start: 412, end: 480, colorIndex: 3 },
];

API

Prop	Type	Default	Description
`phases`	`TimingPhase[]`	`—`	{ label, start, end, colorIndex? }[] (ms)
`showAxis`	`boolean`	`true`	Bottom segment labels
`labelMode`	`'auto' \| 'all' \| 'none'`	`'auto'`	Segment label strategy; auto hides colliding labels
