Small multiples in Web Component

One chart per category, on a shared scale

multiples: col

This draws one small chart per category on a shared scale, laid out as a grid of charts. It lets you compare many groups at once without overlaying them, so each category reads on its own but against the same yardstick.

Building…

Loading a live grid…

This is the web component version. A lattice-grid custom element renders the grid with no build step, its configuration set as a property, so it works on a page that has no bundler at all.

The configuration

<link rel="stylesheet" href="https://cdn.latticegrid.dev/lattice-grid@1.107.0/lattice-grid.min.css">

<script type="module">
  import { defineLatticeGrid } from 'https://cdn.latticegrid.dev/lattice-grid@1.107.0/modules/webcomponent.esm.min.js';
  defineLatticeGrid();
</script>

<div id="chart" style="height: 340px"></div>
<lattice-grid row-key="id" style="display: block; height: 320px; margin-top: 14px"></lattice-grid>

<script type="module">
  import { createChart } from 'https://cdn.latticegrid.dev/lattice-grid@1.107.0/modules/charts.esm.min.js';

  const el = document.querySelector('lattice-grid');
  el.config = {
    columns: [
      { field: 'circuit', title: 'Circuit', layout: { width: 180 } },
      { field: 'region', title: 'Region', filter: { type: 'set' } },
      { field: 'status', title: 'Status', filter: { type: 'set' } },
      { field: 'bandwidth', title: 'Bandwidth', type: 'number' },
      { field: 'charge', title: 'Monthly charge', type: 'number',
        format: { style: 'currency', currency: 'GBP' }, total: 'sum' },
    ],
  };
  el.rows = rows;  // an array of circuit records

  // multiples draws one small chart per region on a shared scale, so they read
  // against each other. The chart reads el.grid, the live grid inside the
  // element, so all the panels follow the table together.
  createChart({ grid: el.grid, container: '#chart', type: 'bar', x: 'status', y: 'charge', multiples: 'region' });
