Data extraction for figure

Hey,

Could someone please extract the data for Data 1, Data 2, and Data 3 from the figure? I would like to use the digitized data for my analysis. If you could provie data in .csv file that would be appricated.

There are a number of File Exchange contributions designed to help extract data from images. See https://www.mathworks.com/matlabcentral/fileexchange/?q=tag%3Adigitize

Hello,

I tried them, since there are three data sets the code gets confused.

Please upload the figure, and I'll extract data into CSV.

with Grabit GRABIT - File Exchange - MATLAB Central it was fairly easy to scan seperatly your 3 curves - attached the results

of course it's a manual approach - if you need somehing more automatic yu may have to use an image processing approach

load('Data001.mat')
load('Data002.mat')
load('Data003.mat')

plot(Data001(:,1),Data001(:,2))
hold on 
plot(Data002(:,1),Data002(:,2))
plot(Data003(:,1),Data003(:,2))
hold off
