摘　　要：本文探讨LabVIEW平台下基于Windows API函数的波形图绘制方法。利用钩子技术拦截操作系统的WM_PAINT消息,以解决图形的刷新、重绘与显现,该方法具有较强的新颖性。通过动态链接库的方法,实现LabVIEW和Windows API的无缝链接,提高了Labview编程的灵活性和效率。This article studies the way to draw waveform with the windows API function under LabVIEW platform. By introducing an essential method of clasp technology to capture the system＇s WM_PAINT messages, which is original, several problems such as graph refreshing and redrawing and displaying were solved. Seamless link of LabVIEW and the windows API was achieved through the dynamic link librarys（DLL）, which increased of flexibility and efficiency of Labview programming.
