园内有战友提到应用EngaugeDigitizer软件对KM生存曲线进行提取原始数据。为此，本人在官网下载了该软件4.1官方版并试用，确实很方便。具体使用方法可以参见davidlly战友的帖子《如何应用Engauge Digitizer软件提取文献中的数据》http://www.dxy.cn/bbs/thread/13011769?keywords=EngaugeDigitizer%C8%ED%BC%FE#13011769

Engauge Digitizer - Manual Line Graph Tutorial

Manually Digitizing A Line Graph Image

The following steps manually digitize a linear cartesian graph with one curve. These steps are essentially the same as the steps involved in manually digitizing a point graph.

Import the testcase.png case from the Samples directory, using File/Import as shown. Not shown are the other methods of importing: using the "-import" command line option, by copying and pasting, and by dragging and dropping

Click on the Axes Point button before entering axes points. These will define the coordinate system

Click on one of the axes to add the first axes point, then enter its graph coordinates

Click on one of the axes to add the second axes point, then enter its graph coordinates

Click on one of the axes to add the third axes point, then enter its graph coordinates

Click on the Curve Points button before entering curve points. These will contain the digitized graph data

Click on the curve to add a curve point. Repeat until the graph is covered with a sufficient number of curve points. If this step is too slow and tedious, you can first automatically digitize entire segments at a time using segment fill

Export the curve points into a tabular text file using the File/Export As menu option as shown. Not shown are the other methods of exporting the curve points from the curve geometry window: copying and pasting, and dragging and dropping
