docusignapi - Docusign anchor tab positioning is incorrect -

Using API I am creating a new document with 2 embedded signatories. I'm defining the anchor tabs are hard and have all sets with a 3.5 centimeter x offset.

Although formatting is completely closed, no one can understand why he is?

In addition to each entry I Labels defined for the fields are also not visible. Why is this for any reason?

  array ("anchorString" => gt; $ tabArray ['counterSignDate'], "anchor xoffet" = & gt; "3.5", "anchorYoffset" =>, "0" "AnchorIgnoreIfNotPresent" = & gt; "true", "anchorUnits" => "cms")  

It seems that the setting of the offset is relevant to the beginning of the anchoring! Not very clear in the API!
