Click a chart to filter in Vue

Click a slice and the grid narrows to it

chart.on('click', …)

This lets you click a slice or bar in a chart and narrows the grid to it. It turns a chart into a filter control, so a reader drills from the picture into the exact rows behind it with one click.

Building…

Loading a live grid…

This is the Vue 3 version. A createLatticeGrid component takes the configuration through v-bind, and reactive data flows straight into the grid, so it updates the way the rest of your Vue app does.

The configuration

<link rel="stylesheet" href="https://cdn.latticegrid.dev/lattice-grid@1.107.0/lattice-grid.min.css">
<style>
  #chart { height: 260px; }
  #grid { margin-top: 14px; }
  #grid > div { height: 340px; }
</style>
<div id="app"></div>

<script type="module">
  import * as Vue from 'https://esm.sh/vue@3/dist/vue.esm-browser.prod.js';
  import { createGrid } from 'https://cdn.latticegrid.dev/lattice-grid@1.107.0/lattice-grid.esm.min.js';

  const LatticeGrid = createLatticeGrid({ vue: Vue, createGrid });

  Vue.createApp({
