Brushing a time range in Vue

Drag a range on the chart and the grid narrows to it

brush: true

This lets you drag a range across a time chart and narrows the grid to it. It gives a reader a quick way to focus on a period, selecting the window on the chart and reading the matching rows in the grid.

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: 300px; }
  #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';
  import createLatticeGrid from 'https://cdn.latticegrid.dev/lattice-grid@1.107.0/modules/vue.esm.min.js';
  import { createChart } from 'https://cdn.latticegrid.dev/lattice-grid@1.107.0/modules/charts.esm.min.js';

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

  Vue.createApp({
    components: { LatticeGrid },
    data() {
      return {
        config: {
          rowKey: 'id',
          columns: [
            { field: 'date', title: 'Date', type: 'dateString', layout: { pin: 'start', width: 150 } },
            { field: 'price', title: 'Price', type: 'number', format: { decimals: 2 } },
            { field: 'volume', title: 'Volume', type: 'number', format: { notation: 'compact' } },
          ],
          rows,  // one row a day: date, price, volume
        },
      };
    },
    mounted() {
      // The component exposes the live grid via a template ref, which the chart draws from.
      const grid = this.$refs.grid.grid();
      // brush lets a reader drag a range across the chart to narrow the grid to those days.
      createChart({ grid, container: '#chart', type: 'line', x: 'date', y: 'price', brush: true, title: 'Price over time (brush to filter)' });
    },
    template: `
      <div id="chart"></div>
      <div id="grid"><lattice-grid ref="grid" v-bind="config" /></div>
    `,
  }).mount('#app');
