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.

- - WebPlotDigitizer is the most popular Open Source & free alternative to GraphClick.
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.

Comments about Engauge Digitizer as a Alternative to GraphClick
Graph click allows you to specify the axes coordinates one axis at a time. Engauge requires that you know both coordinates along each axis. This is not often possible. I have a graph where I don't know the x and y coordinates for the axes -- just one or the other. For certain types of graphs, Engauge is useless.0
Plot Digitizer is a 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.

Opinions about Plot Digitizer as a Alternative to GraphClick
PlotDigitizer is data extraction software. It allows users to extract data points from graphs, plots, charts, and scanned documents.
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!

Very easy to use and works well.1
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.
Datafromchart operates as a web-based application, offering users the capability to extract data directly from charts. Designed with analysts and researchers in mind, it facilitates the extraction of estimates from various sources such as industry reports or research papers.
Graphs are great for understanding results in reports and papers, but to use those results in your own analysis, you'll want the underlying numerical data. Your analysis will be more flexible because you can easily include all the data from the graph, rather than just a few...
