Marking a baseline in Vue

"Mark all" resets every delta to now

grid.statistics.rebase(col)

This grid resets every delta to now with a single 'mark all', setting a fresh baseline. It lets a reader say 'watch from here', so change tracking restarts from the current moment rather than page load.

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 { margin-top: 8px; }
  #grid > div { height: 440px; }
</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 },
    data() {
      return {
        config: {
          rowKey: 'id',
          columns: [
            { field: 'symbol', title: 'Symbol', layout: { pin: 'start', width: 120 } },
            { field: 'price', title: 'Price', type: 'number' },
            { id: 'delta', title: 'Change', shadow: { of: 'price', kind: 'delta' }, type: 'number', format: { signed: true } },
            { id: 'first', title: 'Baseline', shadow: { of: 'price', kind: 'firstValue' }, type: 'number' },
          ],
          rows,  // one symbol per row
        },
      };
    },
    methods: {
      // rebase moves every baseline to the current value, so the deltas start again.
      markAll() {
        this.$refs.grid.grid().statistics.rebase('price');
      },
    },
    template: `
      <div>
        <button @click="markAll">Mark all</button>
        <div id="grid"><lattice-grid ref="grid" v-bind="config" /></div>
      </div>
    `,
