Colour schemes in Angular

Built-in palettes, the default colour-blind safe

scheme: 'default' · 'bright' · 'earth' · 'mono'

This shows the built-in colour palettes, with the default chosen to be colour-blind safe. It lets you match a chart to your product's palette while keeping the categories distinguishable for every reader.

Building…

Loading a live grid…

This is the Angular version. A standalone component takes the whole configuration through one config input, surfaces grid events as outputs, and exposes the live grid on a getter for anything the inputs do not cover.

The configuration

import { Component, ViewChild } from '@angular/core';
import { bootstrapApplication } from '@angular/platform-browser';
import { createGrid } from '@toclocoinc/lattice-grid';
import '@toclocoinc/lattice-grid/css';
import { createChart } from '@toclocoinc/lattice-grid/modules/charts';
import { LatticeGridComponent, provideLattice } from '@toclocoinc/lattice-grid/angular';

const columns = [
  { field: 'region', title: 'Region', filter: { type: 'set' } },
  { field: 'status', title: 'Status', filter: { type: 'set' } },
  { field: 'bandwidth', title: 'Bandwidth', type: 'number' },
  { field: 'utilisation', title: 'Utilisation', type: 'number', format: { decimals: 1, suffix: '%' } },
  { field: 'charge', title: 'Monthly charge', type: 'number',
    format: { style: 'currency', currency: 'GBP' }, total: 'sum' },
];

const rows = [/* circuit records */];



@Component({
  selector: 'app-root',
  standalone: true,
  imports: [LatticeGridComponent],
  template:
    '<div style="display:grid;grid-template-columns:repeat(2, 1fr);gap:14px;height:210px">' +
    '<div id="default"></div>' +
    '<div id="bright"></div>' +
    '<div id="earth"></div>' +
    '<div id="mono"></div>' +
    '</div>' +
    '<lattice-grid [config]="grid" (grid-ready)="onGridReady()" style="display:block;height:340px;margin-top:14px"></lattice-grid>',
})
export class AppComponent {
  @ViewChild(LatticeGridComponent) gridRef!: LatticeGridComponent;

  grid = {
    rowKey: 'id',
    columns: columns,
    rows: rows,
  };

  // The grid is created once the view has rendered, so the live instance
  // arrives on grid-ready rather than in ngAfterViewInit.
  onGridReady() {
    const grid = this.gridRef.grid;
    createChart({ grid, container: '#default', type: 'pie', x: 'region', y: 'charge', scheme: 'default', title: 'default' });
    createChart({ grid, container: '#bright',  type: 'pie', x: 'region', y: 'charge', scheme: 'bright',  title: 'bright' });
    createChart({ grid, container: '#earth',   type: 'pie', x: 'region', y: 'charge', scheme: 'earth',   title: 'earth' });
    createChart({ grid, container: '#mono',    type: 'pie', x: 'region', y: 'charge', scheme: 'mono',    title: 'mono' });
  }
}

bootstrapApplication(AppComponent, {
  providers: [provideLattice({ createGrid })],
});
