Hello,
Can anyone tell me if I want to know the original values of a log scale y-axis for a figure?
Thanks

The Data Cursor tool will report in original values not in log() of the values.
If you get() the YData property of a graphics object that is on a log plot, then the YData will be in the original coordinates, not in log() coordinates.

What form is the plot in? Is it an image file with lines drawn in the image? Is it a MATLAB .fig file? Is it a plot that exists "on screen" after you run some software?

It is a plot that I got for some linear-scale x-axis (as the authors named it) and a log scale y-axis. The image is attached
Thanks
