I have written the following code in MuPAD. And now I tried to plot "Pb versus sigmas" in Matlab using "semilogy" command. But my Y-axis is still linear, it did not change to logarithmic scale.

This is the linear image: This is the Y axis log scale image: They are same except the fake log scale Y axis. My original code is : imagesc (x,y,log10 (image_spectrogram (1:floor (Fs/2),:)+1)); cmap = colormap ('gray'); colormap (flipud (cmap)); caxis (log10 ( [0.9,max (image_spectrogram (:))*0.2])); set (gca,'YScale','log','YDir','normal','YTick',

Edited: David J. Mack on 3 Oct 2017. Have you tried to use semilogy instead of loglog, e.g.: semilogy (x,y); If you have to use loglog, use the 'XScale'-Property instead: loglog (x,y); set (gca,'XScale','linear'); In both cases you can set the x-tick & the x-axis limit, using: Deletting X and Y axes ticks; Plotting multiple Magnitudes in one plot; Problem with 2nd axis Yticks with plotyy and semilogy; Logspace boundary of 2*10^b; Spectrogram x axis logarithmic; Defining matlab logspace for semilogx plot; Fontsize and properties of Xticklabels using figure handles; X Tick Labels skipping certain values The y axis is log10 the x axis is linear loglogxy Plots vector x versus vector from PRO 2514 at Davenport University Log scale on both axes. To create a plot using a log (base 10) scale for both the x-axis and and the y-axis you can use the function loglog. Plot the values k -0.4 for k = 1, 4, 9, 100 2 using linear scales on both axes, a log scale on the x-axis and log scales on both axes.

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. I want to change the y-axis ticks into 10 base power format. Actually, the y-axis is the log of any data. but i need y-axis in 10^ format.

My original code is : imagesc (x,y,log10 (image_spectrogram (1:floor (Fs/2),:)+1)); cmap = colormap ('gray'); colormap (flipud (cmap)); caxis (log10 ( [0.9,max (image_spectrogram (:))*0.2])); set (gca,'YScale','log','YDir','normal','YTick', MATLAB: Log ticks on Y-axis. I am new to matlab and try to reproduce ticks on the Y-Axis according to a %b=log10(8000); %yc1=logspace(2,b,23); yc2=linspace 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.

% 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. For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ).

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.

Why is the y-axis labeled in kg rather than the log of kg? The semilogy function, chooses major tick marks that  Plotted lines are: y = 10x (red), y = x (green), y = log(x) (blue).

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. I am plotting x-y plot using plot function. I want to set only y-axis as log scale and x-axis as linear?
