Dear all,

What's the best way, in your opinion, to extract data from a figure in a published paper. I am doing modelling and want to compare my results with well established and recognized results in a published paper. I am wondering if there is some nice software which can do this job well and in an easy way. Thanks a lot for your experience.

I dont know about the "best" but this does the job

http://digitizer.sourceforge.net/

http://plotdigitizer.sourceforge.net/

this one works too.

Well this thread is old, but I'm still posting a reply since this shows up on Google when you search for this stuff.

There's a web based program: http://www.arohatgi.info/WebPlotDigitizer/

Yes, I made it :P

[mukut]

thanks. I have collected all these software for my future need.

I downloaded the software but it needs registration code.
Could you please send me the registration code via email?

Guys, few years ago, I extensively used a wee code called Windig, it was pretty convenient as it had a cool magnifier and could rotate the scanned images or whatever as you wished. Simple and functioning. I still have the zipped file, should anyone want to have it, just ask me to send an e-mail to you. Unfortunately, it doesnt work on 64bit OSs. Take care, Pano

Hello pano
Would you please mail that for me?

I am currently developing my web-based program which I mentioned above to be able to automatically detect points on curves and deal with polar and ternary diagrams as well. This will take some time, but I'll update the group once I've done all that and you can perhaps suggest more features to add.

I have completed the second version on my web based program to extract data from plots. You can check it out at http://arohatgi.info/WebPlotDigitizer

I have also made a convenient Chrome app for it.

This version supports XY charts, polar plots, ternary diagrams and maps. I have included an auto extraction system in it which can pull out large number of points for fairly uncomplicated plots.

You need Firefox 3.6+ or Chrome 6+ to use this. You don't need to install anything else for this.

looks wonderful! thank for your effort. i'll test it asap.

That was easy and wonderful.....THANKS

em student of engg.

guys i have just started with CFD
& i use Tecplot for extracting the data, for above purpose;
What r the merits of above aplications over it.

pls reply.

Hey can anone tell me how to apply orthgonality in grids.
I have developed C Code for elliptical equations.
(Cylinder placed in a fluid channel).

thanks

Hi,
Last time I read a book including this topic. After coding based on some equations in that book, I generated an orthogonal mesh.

Sorry that I forgot the title of that book.
Best wishes
Dave
