Dear scholar, I want to extract/ find data from publish article for calibration.
See the attached id-VG. I want data point Si TFET.
Plz help.
I have done it for image files some time ago using free software, but I can't remember what the program was.
This question's answers should get you started ...

The easiest way to do this is to ask the author of the paper for the data. This could take awhile. If you want to do it yourself, you can use GIMP or Fiji to get the pixel location of the points and the axes on your bitmap, then convert the points to actual positions using the axes values. I have done this with GIMP, using its measure function, and it works, but is tedious. Fiji is an image processor, so you should be able to calibrate the bitmap and just read off points. I have never done this with Fiji, but have done similar things.
Note that both GIMP and Fiji (ImageJ) are free and open source. Send the developers a bit of cash if they prove useful, so we can keep enjoying their efforts.
I've had good luck with a web app called WebPlotDigitizer (I think you can also download it as a desktop app if you like). Good luck!

Also, consider this : WebPlotDigitizer. it has some automation tools.

Make use of Origin software or Plot digitizer online tools for data extractions.
