Hi,
you must use "Property nodes" of your graph controls. Rigth-click on them and select "Create->Propery node" from menu. The node will be created on the diagram. Right click on it and go to "Properties->X Scale->..." or "Y scale->...". There you will find a lot of scale properties such as range, increment, stule, format etc. Choose one you want to edit programatically. Now you can change this propery by wiring the appropriate value to the property node. If you need to change sacles of several controls you must create property node for each of them.
Good luck.
