摘要
用VB的Line方法绘制连续曲线,分析了当绘图数据量较大时,实时性较差的原因;介绍了采用Windows的API函数来绘制连续曲线方法;详细阐述了用API函数绘制连续曲线在绘图实时性方面的优势,并以绘制灭菌柜温度曲线为例,给出了在VB环境下用API函数绘制连续曲线的步骤及主要代码。
In this paper, the reasons for the plotting real time capability using VB's Line method are insufficient when plotted data are a lot. An approach of plotting continuous line by windows API functions is introduced. Advantages of plot continuous lines by API functions are presented in detail. By illustrating drawing temperature curves in kill-bacterium tank, and the process and main codes using API functions to plot continuous line are given.
