Best Plot Digitizer Alternatives
Plot Digitizer is described as 'Java program used to digitize scanned plots of functional data. Often data is found presented in reports and references as functional X-Y type scatter or line plots. In order to use this data, it must somehow be digitized' and is an app. There are more than 10 alternatives to Plot Digitizer for Windows, Linux, Mac, Online / Web-based and Java. The best alternative is WebPlotDigitizer, which is both free and Open Source. Other great apps like Plot Digitizer are Engauge Digitizer, g3data, PlotDigitizer and GraphClick.
A large quantity of published data is available only in the form of plots and it is often difficult to extract numerical data accurately out of these pictures. There are several softwares available to aid this process, but most are either paid or poorly written.
This open source, digitizing software converts an image file showing a graph or map, into numbers. The image file can come from a scanner, digital camera or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet.
g3data is used for extracting data from graphs. In publications graphs often are included, but the actual data is missing. g3data makes the extracting process much easier.

PlotDigitizer is data extraction software. It allows users to extract data points from graphs, plots, charts, and scanned documents.
GraphClick is a graph digitizer shareware for Mac OS X which allows to automatically retrieve the original (x,y)-data from the image of a scanned graphor fom QuickTime movies. Free download. Features automatic detection of solid, dashed or dotted lines, bar charts or symbols.
Sometimes it is necessary to extract data values from graphs, e.g. in most scientific publications only plots but no data values are published. DigitizeIt makes it easy to actually get back numbers from such a plot!
UN-SCAN-IT graph digitizer converts scanned graphs to real xy data automatically. Extract xy data values from published graphs, old plots, and strip charts.
jTechDig is a software tool written in Java for digitizing data from an image of graph or plot. jTechDig can import images from .gif, .bmp, .png etc. files. After mapping of the coordinates system the data can be digitized manually by clicking the mouse.
