Currently, there are some stations still using manual methods to draw the three-line graph, plotting directly on the squared paper, with low efficiency, poor accuracy and inconvenient store and query. LabVIEW is a graphical language，with the advantages of convenient programming and powerful function. The user interface which is developed in LabVIEW has the distinguishing feature what you see is what you get. A weather three-line graph drawing software is designed with LabVIEW in the paper, which extracts temperature, humidity and atmospheric pressure data from the Z file, created by OSMO 2004, and store the data in the Access database to quickly query data and draw the three-line graph. The software is also with friendly interface and easy operation. Key words: LabVIEW; Three-line graph; Z file; Database 1 引言 气象三线图即单站气温、相对湿度、气压变化曲线图，从三线图
