Create a table chart

This is the official documentation of the agent_ruby Ruby agent.

Our first Smart Chart example will be a simple table: however you may choose to make it as complex and customized as you wish.

We will code it in 3 steps:

1. create the chart values in your Agent (so that the data can be dynamically loaded),

2. load that data inside of the component (and passing it down to the template),

3. write the template.

Component

import Component from '@glimmer/component';
import { inject as service } from '@ember/service';
import { tracked } from '@glimmer/tracking';

export default class extends Component {
  @service lianaServerFetch;
  @tracked users;

  constructor(...args) {
    super(...args);
    this.fetchData();
  }

  /** Load data from agent, and pass it to the template */
  async fetchData() {
    const response = await this.lianaServerFetch.fetch(
      '/forest/_charts/mytablechart',
      {},
    );
    this.users = await response.json();
  }
}

Template

<BetaTable
  @columns={{array 'Username' 'Points'}}
  @rows={{this.users}}
  @alignColumnLeft={{true}}
  as |RowColumn user|
>
  <RowColumn>
    <span>{{user.username}}</span>
  </RowColumn>
  <RowColumn>
    <span>{{user.points}}</span>
  </RowColumn>
</BetaTable>
