Sparkline

Inline micro trend line, often used as the trend indicator on KPI cards.

Basic usage

Data is passed via props and rendered as pure SVG, with no third-party charting dependency. Colors are drawn from the --viz-1..8 tokens and are colorblind-friendly.

背景

上升 13下降 4平稳 6

<script setup lang="ts">
import { CfSparkline } from '@chufix-design/vue';
const trendUp = [3, 5, 4, 7, 6, 9, 11, 10, 13];
const trendDown = [12, 11, 13, 9, 10, 7, 8, 5, 4];
const flat = [6, 6, 7, 6, 7, 6, 6, 7, 6];
</script>

<template>
  <div class="demo-row" style="align-items: center; gap: 24px;">
    <span>上升 <CfSparkline :data="trendUp" filled smooth :color-index="0" /> 13</span>
    <span>下降 <CfSparkline :data="trendDown" filled smooth :color-index="3" /> 4</span>
    <span>平稳 <CfSparkline :data="flat" :color-index="2" /> 6</span>
  </div>
</template>

<CfSparkline ... />

8-color palette

colorIndex (0..7) picks any color in --viz-1..8 — colorblind-friendly and aligned with chart series colors.

<script setup lang="ts">
import { CfSparkline } from '@chufix-design/vue';
const data = Array.from({ length: 14 }, (_, i) => 5 + Math.sin(i / 2) * 4 + Math.random() * 2);
const labels = ['indigo', 'amber', 'green', 'red', 'cyan', 'magenta', 'lime', 'azure'];
