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.
Positive & Negitive Log10 Scale Y axis in Matlab (4 answers) Closed 5 years ago. I have a set of data, which should be plotted in a loglog scale. x-values are always
Specifically I'd like log y-axes. It appears that the relevant properties are not exposed so I'll have to do it the long way, unless anyone has any suggestions. Dear all, an annoying issue when plotting on log scales, is apparently not being able to control the format of axis tick labels. For example: given XTick = [0.1,1,10,30]; I want to manually set my own labels, e.g.
For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( … MATLAB: FFT from measured data – Scaling y-axis. digital signal processing fft MATLAB scale scaling signal unless you square ‘FFT’ or use the equivalent ‘20*log10 clarified explanation. Related Question. How to convert data from dBW units to dBm in MATLAB 7.5 (R2007b) MATLAB FFT (y-axis values) I get the peaks at the wrong loglog (X,Y) plots x - and y -coordinates using a base 10 logarithmic scale on the x -axis and 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. loglog (X,Y) plots x - and y -coordinates using a base 10 logarithmic scale on the x -axis and the y -axis.
p <- 10^(seq(-4,0,0.2)). Du vill att dina x-värden ska vara jämnt fördelade på en log10-skala. plot(p,trans, ylim = c(0,1), ylab='coeff', log='x', axes=F). Då kan du
So is it power? I have the signal in the time domain. Is there a way to check if the FFT plotting is correct? Thanks.
Hi again. If the 20*log10 is not included, what would be the y-axis units please? The equation for decibels is A = 10*log10(P2/P1). So is it power? I have the signal in the time domain. Is there a way to check if the FFT plotting is correct? Thanks.

how to plot both axis (X and Y axis) as log Learn more about log scale on axis 2. When plotting, why do we need to plot with 10*log10(pxx) instead of only using pxx? Even when I use either ways of plotting, I cant seem to emulate the yrange in the example plot (attached). The closest plot seems to be plot(fxx, 10*log10(pxx), fyy, 10*log10(pyy)) but the yrange is different.
