Programs developed by dataflow visual programming languages (DFVPLs) often contain lots of visual information. If more useful information could be displayed in the limited range of screen, the efficiency of debugging would be improved. We took full advantage of the characteristic of fisheye view that can display both "local detail" and "global context" simultaneously, improved the previous implementation models and algorithms, and solved the problems of using fisheye view on DFVPL such as nest hierarchy, the difference in nodes' size is big and wires are complex. We combined the debugger with fisheye view and proved its practicability and feasibility by some contrastive experiments.
