I'm using the Multi-series Bar 2D and trying to hide the labels.
$arrData = array(
"chart" => array(
"theme" => "fint",
"caption" => "Earnings vs Number of Jobs",
"subcaption" => $occupation_name,
"entityFillHoverColor" => "#cccccc",
"numberPrefix" => "$",
"showCanvasBorder" => "0",
"legendPadding" => "0",
"chartLeftMargin" => "0",
"chartRightMargin" => "0",
"chartTopMargin" => "0",
"chartBottomMargin" => "0",
"placeValuesInside" => "0",
"showLabels" => "0",
"labelDisplay" => "none",
"valueFontSize" => "11"
));
