Wiring is a very important component of editor in dataflow visual programming languages.On the one hand,wiring should represent logical data dependencies;on the other hand,it should be show in an easily comprehended physical form.In order to organically integrate these attributes,the conception of wire-tree is proposed.The relationships of two attributes become both reliant and independent because of using the structure of wire-tree to represent logical attribute and nodes to represent physical attribute.Therefore,wiring supplies enough logical info of interpretive execution and is easy to edit and optimize.This design has been independently implemented in dataflow visual programming language ——LabScene,which can develop virtual instruments.
