Abstract
Background: There is no initial data but only figure to report the results in some articles, but it’s difficult for us to get the detailed and exact data. To solve the problem, we can use some graph software to gain the data we needed if we failed to contact the author of the article.

Objectives: To introduce how to use the AUTOCAD software to get data from the figure, which would be explained by examples.

Methods: We use the AUTOCAD software to gain the survival rate data from figure of a foreign article. We introduce the fundamental and operational approach Through the example.

Results: We have excavated and gained the data from figure by using the software, and we get the survival rate data through eductioned by the principle of drawing.

Conclusions: There is no initial data but only figure to report the results in some articles. If the plotting is standard of precision, we can always get the data exactly through the software.
