You can now use add card with charts from your resources data.

First you need to add the trait HasGraphData to the models that should show chart data.

    ... 
}

The trait has 2 functions which can be extended to show chart data:

public function chartResourceData($selection)
{
    return [
        'labels' => [],
        'datasets' => [],
    ];
}

public function chartDashboardData($selection)
{
    return $this->chartResourceData($selection);
}

return [
    (new \Vemcogroup\Charts\Chart)->onlyOnDetail()
];

(new \Vemcogroup\Charts\Chart())->title('Title of card');
