| Abstract: | 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. |
