Scatter plot

Two-dimensional scatter chart, colored by group.

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

<script setup lang="ts">
import { CfScatterPlot } from '@chufix-design/vue';
const data = Array.from({ length: 60 }, (_, i) => ({
  x: Math.random() * 100,
  y: Math.random() * 100,
  group: i % 4 === 0 ? 'a' : i % 4 === 1 ? 'b' : i % 4 === 2 ? 'c' : 'd',
}));
</script>

<template>
  <CfScatterPlot :data="data" />
</template>

<CfScatterPlot ... />

Multi-group clustering

A point’s group field decides its color; if omitted, it falls into default.

背景

<script setup lang="ts">
import { CfScatterPlot } from '@chufix-design/vue';
function gen(n: number, group: string, cx: number, cy: number, spread = 20) {
  return Array.from({ length: n }, () => ({
    x: cx + (Math.random() - 0.5) * spread,
    y: cy + (Math.random() - 0.5) * spread,
    group,
  }));
}
const data = [
  ...gen(30, 'cluster-a', 30, 30),
  ...gen(30, 'cluster-b', 70, 60),
  ...gen(30, 'cluster-c', 50, 85),
  ...gen(20, 'outliers', 80, 20, 40),
];
</script>

<template>
  <CfScatterPlot :data="data" />
</template>

<CfScatterPlot data={points} />
