API Charts

This is the official documentation of the forestadmin/laravel-forestadmin v2+ and forestadmin/symfony-forestadmin PHP agents.

API charts in the legacy agents were declared using express routes.

In the new agent, you will need to use either the agent.addChart or the collection.addChart function, depending on if the chart is to be displayed on a record of a collection or a dashboard.

You can find the full documentation of chart customization here.

Code cheatsheet

Legacy agent	New agent
route in web.php	agent.addChart collection.addChart(...)
render Chart	return resultBuilder.value(...) return resultBuilder.distribution(...)
request object	context.recordId

How to migrate

Migrating should be straightforward: the only differences are that:

• dashboard charts are now declared using the agent.addChart function.

• collection charts are now declared using the collection.addChart function, and access the record id using context.recordId instead of request.query?.record_id.

• Both types should use the resultBuilder helper to return the chart data.

Before

• Define a new route in web.php:

• Setup an action into a controller

<?php

namespace App\Http\Controllers;

use ForestAdmin\LaravelForestAdmin\Facades\ChartApi;
use Stripe\StripeClient;

class ChartsController extends Controller
{
    public function mrr()
    {
        $mrr = 0;
        $stripe = new StripeClient('sk_AABBCCDD11223344');
        $charges = $stripe->charges->all(['limit' => 3]);
        foreach ($charges as $charge) {
            $mrr += $charge->amount;
        }
        return ChartApi::renderValue($mrr);
    }
}

After

<?php

use ForestAdmin\AgentPHP\Agent\Builder\AgentFactory;
use ForestAdmin\AgentPHP\DatasourceEloquent\EloquentDatasource;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Context\AgentCustomizationContext;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Chart\ResultBuilder;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Query\Aggregation;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Query\ConditionTree\ConditionTreeFactory;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Query\ConditionTree\Operators;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Query\Filters\Filter;

return static function () {
	$forestAgent = app()->make(AgentFactory::class);
    $forestAgent->addDatasource(
        new EloquentDatasource(...),
    )
    ->addChart(
    'monthlyRecuringRevenue',
    function (AgentCustomizationContext $context, ResultBuilder $resultBuilder) {
        $mrr = 0;
        $stripe = new StripeClient('sk_AABBCCDD11223344');
        $charges = $stripe->charges->all(['limit' => 3]);
        foreach ($charges as $charge) {
            $mrr += $charge->amount;
        }

        return $resultBuilder->value($mrr)
    }
);
