Statistics without a panel in Vue

Every figure available to your own interface, as an object

grid.statistics.*

This grid exposes every figure it computes as a plain object, for your own interface with no panel involved. It lets you take the statistics into a custom dashboard or export, so the numbers are available wherever you need them.

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@1.108.0/lattice-grid.min.css">
<style>
  #grid > div { height: 460px; }
  #out { margin-top: 12px; }
</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@1.108.0/lattice-grid.esm.min.js';
  import createLatticeGrid from 'https://cdn.latticegrid.dev/lattice-grid@1.108.0/modules/vue.esm.min.js';

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

  Vue.createApp({
    components: { LatticeGrid },
