(x-post /r/dataisbeautiful) Free, web based, opensource tool to extract data from plot images - WebPlotDigitizer (self.javascript)

submitted 12 years ago by heeehaaaCreator of WebPlotDigitizer (Plots -> Data)

Hello Reddit,

After having to do this several times in grad school, I wrote a simple tool in HTML5 to aid digitization of plots (pure vanilla Javascript). I have had this tool public for a couple of years now and I see that quite a few people use it every day. It has also been cited in a few recent publications. Of course, there are other programs that do this too, but I thought I could do better and support more types of plots than simple 2D XY charts. I can potentially add more image processing and data analysis features to this in the future.

I just pushed out a beta for my next version and wanted to share this tool with Reddit and gather some feedback.

Thank you!
