A plot with a log (base 10) scale on the x-axis (semilogx), on the y-axis (semilogy) or both axes (loglog), can be very useful when plotting very large or very small (positive) values.

The messy tick labels are also a pita that's been a continual pet peeve of mine that TMW didn't allow the TeX interpreter in the 'ticklabel' so you have to use text to write them formatted when faced with the problem of log axes with other than the standard decade ranges. There've been a coupld of postings on the subject with the last month or so that illustrates how to solve that minor

In this tutorial, we will go over how to scale a Matlab figure's axes using semilogx, semilogy, and loglog. 3 examples are shown in the video: In the first e

Alternatively, you can set the ‘YScale’ property on the axes: set(gca, 'YScale' , 'log' ) Se hela listan på educba.com And if the data was originally log10(~something~). Can I change the axes in a way that I will see 10^(~something~) in both axes? Meaning the original data, althogh I rescieved it as log(A) Vs log (B) (I didn't get the figure in loglog scailing, it's in linear scailing but the data itself is a log)?

Y = log10(X) returns the common logarithm of each element in array X.The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf,Inf).For complex and negative real values of X, the log10 function returns complex values.

The Horizontal Axis Should Have A Logarithmic Scale That Spans 10° (that Is, 1) To 102 (that Is, 100).

In other words, Matlab tries to use log10(log10(F)) on the y-axis. OP can fix the problem by doing this  value of y where the line crosses the x-axis.

This would help me visualize the data both in terms of wavevector and wavelength. The codes and files are attached herwith.

This is a pretty poor way to represent the y-axis, however,  In science and engineering, a semi-log plot, or semi-log graph has one axis on a logarithmic scale, the other on a linear scale. It is useful for data with  This MATLAB function plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and a linear scale on the y-axis. told Matlab he wants the axis to be logarithmic.
