Question about the log scale in Matlab

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.

Even if I the plot is original? I mean the plot came with the y-axes as the log-scale and it is not I who converted it to log scale. Can Matlab still get the linear y-values of those log scale y-values in the figure?

Thanks

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
