Simple reason: log10(0) is a very small "number". So that is an impossible request. Also when you set the axis limits before plotting the actual plotting command gives you a new axis limits - that are determined by the data you plot. Sometimes, when the "raw" values in the yticks are very small, matlab y axis automatically toggles to scientific notation, whereby the power of ten giving the order of magnitude appears in the top left corner, and the yticks are given in units of that power. Hi again. If the 20*log10 is not included, what would be the y-axis units please?

semilogx (X,Y,LineSpec) 은 지정된 선 스타일, 마커, 색을 MATLAB FFT (y-axis values). Learn more about matlab, fft Python program to plot logarithmic axes using matplotlib.

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.

**kwargs. Different keyword arguments are accepted,  [In MATLAB, log(x) = ln(x) and log10(x) = log10(x).] It's pretty clear that this data is exponential.

works fine. I can change the color scale, axes ranges, and everything through the menus from the created image. However, transforming the image so it displays a log Y axis does nothing to the image. Pixels are still squares of equal size (I think that is the key around my issue). Maybe I need another type of plot? I'm a complete newbe in matlab.

The equation for decibels is A = 10*log10(P2/P1). So is it power?

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.

To plot multiple sets of coordinates on the same set of axes, … 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 … The MATLAB M-file used to create this plot is experr.m. X-axis log scale. To create a plot with a linear scale on the x-axis and a log (base 10) scale on the x-axis you can use the function semilogx.

the image is positioned so that the center of the first pixel is on 0.1, and the center of the last one at 100. That makes each pixel approx. 0.2 wide. However, this is now internally translated to the image patches laying between -0.1 and 100.2. This is apparently calculated in the same way, no matter what mode (lin/log) the axis is in.
