Hi David,
Sample data (CSV):
company,event,source,view Restaurante,"DESCONTO DE 20% NA REFEIÇÃO PARA CLIENTES",app,89 Restaurante,"DESCONTO DE 20% NA REFEIÇÃO PARA CLIENTES",website,141 Empresa,"Test Event",website,133 Empresa,"Test Event",website,134 Empresa,"Test Event",website,135 Empresa,"Test Event",website,136 Empresa,"Test Event",website,137 Empresa,"Test Event",website,138 Empresa,"Test Event",website,139 Loja,PROMOTION,website,4 Loja,FANTASTIC,website,177 Hotel,"some event 123",website,129 Hotel,"some event 123",website,130 Hotel,"some event 123",website,131 Hotel,"some event 123",website,132 Hotel,"some event 456",website,140
as can be seen in the image, PROMOTION and FANTASTIC are repeated.

Hi David,
Is the average calculation working properly?
public function setup()
{
try
{
$this->src('report_datasource')
->pipe(new ColumnMeta(array(
"producer" => array(
'label' => 'Producer',
'type' => 'string',
),
)))
->pipe(new ColumnMeta(array(
"wine" => array(
'label' => 'Wine',
'type' => 'string',
),
)))
->pipe(new ColumnMeta(array(
"source" => array(
'label' => 'Source',
'type' => 'string',
),
)))
->pipe(new ColumnMeta(array(
"review_id" => array(
'label' => 'Count',
'type' => 'number',
"prefix" => "",
'decimals' => 0,
),
)))
->pipe(new ColumnMeta(array(
"eval" => array(
'label' => 'Eval',
'type' => 'number',
"prefix" => "",
'decimals' => 2,
),
)))
->pipe(new Pivot(array(
"dimensions" => array(
"row" => "producer, wine, source",
),
"aggregates" => array(
"count" => "review_id",
"avg" => "eval",
),
)))
->pipe($this->dataStore('datasrc'));
} catch (\Exception $e)
{
error_log($e->getMessage(), $e->getCode());
}
}
In Pivot.php
private function aggValue($aggregate, $value1, $value2) {
switch ($aggregate) {
case 'min':
return min($value1, $value2);
case 'max':
return max($value1, $value2);
case 'count':
return $value1 + 1;
case 'avg':
case 'sum':
default:
return (float) $value1 + (float) $value2;
}
}
At finalize() of Pivot: there is calculation for avg:
foreach ($this->dataFields as $dataField => $aggregate)
if ($aggregate === 'avg') {
foreach ($this->data as $key => $datum)
$this->data[$key][$dataField] =
$this->data[$key][$dataField] / $this->count[$key];
}
Since to calculate average we need to sum first then finally divided by the count. I will ask David to do the test again, if there is a bug we will fix immediately. I will come back to you.
