Digitize a graph with this code.
You can extract data manually or automatically based on the pixel color.
The interface is using the dialogue functions provided by MATLAB (e.g., listdlg, inputdlg, ...)
How to use
  1. Run the code by executing Main.m
  2. Open the image
  3. Calibrate axis by setting two reference x points and two y points
  4. You can calibrate the axis from the file
  5. Once you calibrate the axis, the calibration result is save as file "calibration_last.axis"
  6. Ditigize your data manually or automatically
  7. If you want to add or remove some data, use the menu 'Acquire data manually'
  8. Your data are stored in the variable named 'data'
P.S.
Log scale is not provided.
If you want to digitize a log scaled graph, you'll want to do it mathematically.
Calibrate x and y graph with the log value of x and y, digitize it via this code, and apply the exponential function to the data you obtained.
