Code that handles the case when the 'format_metrics' query parameter value is
'bc' should be removed as well. This code is in API\Request and DataTablePostProcessor.
Should be removed before releasing Piwik 3.0.
/**
* @param DataTableInterface $dataTable
* @return DataTableInterface
*/
public function applyMetricsFormatting($dataTable)
{
$formatMetrics = Common::getRequestVar('format_metrics', 0, 'string', $this->request);
if ($formatMetrics == '0') {
return $dataTable;
}
// in Piwik 2.X & below, metrics are not formatted in API responses except for percents.
// this code implements this inconsistency
$onlyFormatPercents = $formatMetrics === 'bc';
$metricsToFormat = null;
if ($onlyFormatPercents) {
$metricsToFormat = $this->apiInconsistencies->getPercentMetricsToFormat();
