                    'key' => 'disposition',
                    'value' => strtoupper($value),

            PieChart::make()
                ->title('numbers')
                ->model('\App\Models\Asterisk\Cdr')
                ->col_xaxis('calldate')
                ->series($series)
                ->options([
                    'showPercentage' => true,
                    'btnFilter' => true,
                    'btnFilterDefault' => '30',
                    'btnFilterList' => [
                       '30' => '30 Days',
                       '60' => '60 Days',
                       '90' => '90 Days',
