try
{
// create an API client instance
$client = new Pdfcrowd("username", " api key ");
$client->setPageMargins("20mm", "20mm", "20mm", "20mm"); // <<< this is my addition line

$pdf = $client->convertURI('http://dev.cloudwifi.io/detailedAnalyticsHtml.php?iD=37&lang=fr');
// set HTTP response headers
header("Content-Type: application/pdf");
header("Cache-Control: max-age=0");
header("Accept-Ranges: none");
header("Content-Disposition: attachment; filename=\"Analytics.pdf\"");

// send the generated PDF

Hi,

Our Stable API has some issues with charts.

Could you please try the new version of our API to see if it resolves your issue?
The new version is currently in beta and it is free to use.

You can activate access to the new API here:
-- https://pdfcrowd.com/user/account/api2-license/

You need to install the latest PHP client library:
-- https://pdfcrowd.com/api/client-library/php/

Update your code according to the new documentation because new API has somewhat different syntax:
