LineChart 折线图
多 series 折线图,支持平滑曲线、网格线、x/y 轴标签。
基础用法
数据通过 props 传入,纯 SVG 渲染,无第三方图表库依赖。
配色取自 --viz-1..8 token,色盲友好。
背景
<script setup lang="ts">
import { CfLineChart } from '@chufix-design/vue';
const series = [
{ name: 'CPU', data: [20, 35, 30, 50, 65, 45, 60, 75, 65, 80, 70, 85] },
{ name: 'Memory', data: [40, 38, 50, 55, 60, 58, 62, 68, 72, 70, 75, 78] },
];
const labels = ['00','02','04','06','08','10','12','14','16','18','20','22'];
</script>
<template>
<CfLineChart :series="series" :labels="labels" smooth />
</template> <CfLineChart ... /> 平滑曲线
smooth = true 走 Catmull-Rom 风格的 cubic Bezier,控制点取相邻两点的差值乘以 0.2 张力,
不会过冲(不会出现拐点处的”半圆”鼓包)。
背景
smooth = false
smooth = true(Catmull-Rom)
<script setup lang="ts">
import { CfLineChart } from '@chufix-design/vue';
const series = [{ name: 'CPU', data: [20, 35, 30, 50, 65, 45, 60, 75, 65, 80, 70, 85] }];
</script>
<template>
<div style="display: grid; grid-template-columns: 1fr 1fr; gap: 16px;">
<div>
<div style="font-size: 11px; color: var(--fg-3); margin-bottom: 4px; font-family: var(--font-mono);">smooth = false</div>
<CfLineChart :series="series" :height="180" />
</div>

<div style="font-size: 11px; color: var(--fg-3); margin-bottom: 4px; font-family: var(--font-mono);">smooth = true(Catmull-Rom)</div>
<CfLineChart :series="series" :height="180" smooth />
</div>
</div>
</template>
<CfLineChart series={series} smooth /> 多 series
最多支持 8 条同时显示,配色按 --viz-1..8 依次循环。
