If you use xlim([5000 8000]) the plots are superficially the same because the range of x-values is so limited the difference in scaling between the log and linear axes isn't much at all. Widening the scale as I did show how the log axis is foreshortened in the upper half significantly, IF there's a wide-enough range for the log to make any difference.
semilogx (X,Y) plots x - and y -coordinates using a base-10 logarithmic scale on the x -axis and a linear scale on the y -axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. For axes in a 2-D view, the y-axis is vertical with values increasing from bottom to top.
Actually, the y-axis is the log of any data. but i need y-axis in 10^ format. I tried it manually from figure properties settings but when I change it, it shows ^ sign but I need it in the standard format. kindly help me I will be highly thankful to you Hi again.

Buscar Answers Clear Filters axis MATLAB Dear all, I have y-axis with time starting from 0 seconds to 14,000 seconds and I assigned it manually to get the values from an excel sheet and it plots all seconds which is a difference of 10 seconds each and it was too clustered and not able to see it properly because of too many data point in it. How do I present an audio signal in a time Learn more about time-domain_db Hey! I would like to automatically have the y-axis label updated based on the input values for the variable y. In this case I would like the line "-5" in the y-axis label replaced by "10^-5" (with the -5 shown as an exponent).

How to do that? I used loglog function but it scales both axis but I want only Y. semilogy function. Alternatively, you can set the 'YScale' property on the axes:.
The most common base of any logarithmic equation is always considered to be 10 if it is not specified. The log of negative real values is equal to the log of the positive value, plus (pi*1i) -- that is the result is complex. When you set YScale to log, then internally it would take the log of the negative values you have, and would found that the log is complex.
