GraphClick is not available for Windows but there are some alternatives that runs on Windows with similar functionality. The best Windows alternative is Engauge Digitizer, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 10 alternatives to GraphClick and ten of them are available for Windows so hopefully you can find a suitable replacement. Other interesting Windows alternatives to GraphClick are Plot Digitizer, DigitizeIt, g3data and jTechDig.
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.
Engauge Digitizer is the most popular Windows & Linux alternative to GraphClick.
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.
Some users think Plot Digitizer is a great GraphClick alternative, some don't.
Plot Digitizer is the most popular Mac alternative to GraphClick.
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.
DigitizeIt is the most popular commercial alternative to GraphClick.
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.
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.
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.
im2graph is a free digitizing software that converts graph-images to graph-data, that is to numbers.
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...
Take any graph or data from any source (Web or PDF document, for example), add your comments, and perform any manipulations, like nonlinear regression or curve fitting. Then print your results or export them to Excel or other database.

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.
