Graphreader is meant to be a simple online tool for extracting values from image based graphs and plots, and export those data into comma seperated values (CSV).
Graphs and curves are effective tools for presenting results in reports and publications, however they are also effective means of manupulation since it can be a challenge to grasp and compare the exact values. With graphreader it is time to go deeper into those data and carry out real quantitative analysis.
Obviously, the resulting values will at best be an approximation to the original data set, and you need to do your own data validation, especially when using the machine estimation feature. There may easily be slight offsets and systematic errors, however normally you will get a good idea of the actual data.
Uploaded data will not be used or shared in any way, however since I am not in full control how data is stored and backed up on this hosted cloud serve, please dont upload any confidential material.
