Right now MATLAB either omits the last label if XTickLabelModel is 'auto' or can display strings of the type '10^X' or can show only numbers as decimals (i.e. '0.1, 1, 10, 0.1'). Is there a way to control directly the format of axis tick labels, or I have to work it around using a text(-) object and switching XTickLabels off?

Thanks for the answer Mr Roberson, but i still have the problem, the way you suggest me doesn't change the scale, what i meant it was that i need to use decade from 0.5 to 5 and 5 to 50.

Square root: log(a) math.log(a) Logarithm, base $e$ (natural) log10(a) math.log10(a) Logarithm, base 10 6 Ratings. The formula for the exponent of 12783 is: 4 = INT (LOG10 (ABS (12783))) There MATLAB adjusts the x-axis, y-axis, and z-axis so that they have equal lengths  This plots the logarithmic scale in the x and y-axis. In the x-axis, it ranges from 10 ^-2 to 10^1 and the graph is plotted according to the above plot. Example  exams using Matlab, Agilent VEE, or even with bare hands, where the hori- logarithmic scale meaning that their horizontal axis is log10 ω (or our x!).

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. MATLAB FFT (y-axis values).

I have data in multiple y and z axis x-axis is fixed while y-axis is varying with eah value of x and z is fixed for each (x,y) pair. as shown in below figure for example red colour show the fixed value of z-axis (color bar) and y is vary w.r.t x..

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.

To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. Positive & Negitive Log10 Scale Y axis in Matlab. Ask Question Asked 7 years, 3 months ago. Active 1 year ago.

Using the imagesc function, I can shown the image. eg: imagesc(x,y,log10( image_spectrogram+1));. I am trying 

% data x = -3:0.1:3; y = sign(x).*10.^abs(x); % scaling function scale = @(x) sign(x).*log10(abs(x)); N = 7; % number of ticks desired % picking of adequate values for the labels TickMask = linspace(1,numel(y),N); YTickLabels = y(TickMask); % scale labels and plotdata, remove NaN ->inconsistency, do you really want that? Y = log10(X) returns the common logarithm of each element in array X. The function accepts both real and complex inputs.

Matlab log10 y axis

For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ). If you want negative values to be displayed where the corresponding positive value would be displayed, then plot with abs(y) instead of y. Remember, when you use log, there is an infinite distance in log scale between y = 1 and y = 0, since it has to pass through y = exp(-1), y = exp(-2), y = exp(-3), and so on, each of which needs to be allocated the same screen distance as between y = exp(0) and y = exp(1) . 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).

h = pcolor(x,y,log10(image_spectrogram(1:floor(Fs/2),:)+1)); h.EdgeColor = 'none' ; What pcolor is doing is actually creating a surface object and setting the view so that you're looking down from the top.

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. I want to change the y-axis ticks into 10 base power format.

The. semilogy(X,Y) plots x- and y-coordinates using a linear scale on the x-axis and a base-10 logarithmic 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.
