Plot Digitizer is a Java program used to digitize scanned plots of functional data. An easy to use Java program that allows you to digitize data points off of scanned plots, scaled drawings, or orthographic photographs. Includes an automatic digitization feature that can automatically digitize many types of functional data.

The numbers can then be saved to a text file and used where ever you need them. Plot Digitizer works with both linear and logarithmic axis scales. Besides digitizing points off of data plots, this program can be used to digitize other types of scanned data (such as scaled drawings or orthographic photos).
Plot Digitizer includes a special "semi-auto" digitizing feature. For plotted data that trends from left to right, you can simply indicate what data you want digitized with a thick paint brush and the program will automatically sort out grid lines, noise, etc, and will attempt to digitize the line for you.

If you want to use the auto-digitize feature, you must acquire and install the autotrace program separately. Also, the autotrace program must appear on the user's search path. After installing or building autotrace, add it to the search path.
