Svelte versions

Since v11, the library and the examples use runes instead of the Svelte store API. See the v10 documentation archive for examples of those components.

Install

npm install --save layercake

Example

<script>
  // The library provides a main wrapper component
  // and a bunch empty layout components...
  import { LayerCake, Svg, Html, Canvas } from 'layercake';

  // ...that you fill with your own chart components,
  // that live inside your project and which you
  // can copy and paste from here as starting points.
  import AxisX from './components/AxisX.svelte';
  import AxisY from './components/AxisY.svelte';
  import Line from './components/Line.svelte';
  import Scatter from './components/Scatter.svelte';
  import Labels from './components/Labels.svelte';

  const data = [
    { x: 0, y: 1 },
    { x: 1, y: 2 },
    { x: 2, y: 3 }
  ];
</script>

<style>
  .chart-container {
    width: 100%;
    height: 500px;
  }
</style>

<div class="chart-container">
  <LayerCake
    x='x'
    y='y'
    {data}
  >
    <Svg>
      <AxisX/>
      <AxisY/>
