how to total calculation total = total - 'evsel atık'

Hi Oya , maybe help you this url https://www.koolreport.com/docs/pivot/overview/ look at here array in sum like this

"aggregates"=>array(
            "sum" => "dollar_sales",
            "count" => "dollar_sales"
)

I don't want to add a new label. I just want to extract 'Evsel Atık' from the total.

how can i make total account?

I NEED TOTAL CALCULATION : total = total - 'evsel atık'

I NEED TABLE

    $dataStore = $this->getDataSource()->query($this->query)->pipe(new ColumnMeta(array(
        "WEIGHT"=>array(
            'type' => 'float',
        ))));
    $dataStore->pipe(new Pivot(array(
            "dimensions" => array(
                "column" => "TURNAME",
                "row" => "WDATE"
            ),

            "aggregates"=>array(
                "sum" => "WEIGHT"
            ),
        )
    ))->pipe($this->dataStore($this->reportName));

"domestic waste" data is coming. Not adding "domestic waste" data to the total we want
