For axes in a 2-D view, the y-axis is vertical with values increasing from bottom to top. ij — Reverse direction. For axes in a 2-D view, the y-axis is vertical with values increasing from top to bottom.

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

I have the signal in the time domain. Is there a way to check if the FFT plotting is correct? Thanks. I want to change the y-axis ticks into 10 base power format. Actually, the y-axis is the log of any data.

I have the signal in the time domain. Is there a way to check if the FFT plotting is correct? Thanks. 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.

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.

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.

The ability to directly plot a histogram with a logarithmic x-axis is not available in MATLAB. To work around this issue, use the HIST function to plot the histogram, and them use set(gca, 'xscale' , 'log' )

Widening the scale as I did show how the log axis is foreshortened in the upper half significantly, IF there's a wide-enough range for the log to make any difference.

but i need y-axis in 10^ format. I tried it manually from figure properties settings but when I change it, it shows ^ sign but I need it in the standard format. kindly help me I will be highly thankful to you I have written the following code in MuPAD. And now I tried to plot "Pb versus sigmas" in Matlab using "semilogy" command.

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.

Use your actual data as labels, but scale the plotted data with log10. % 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?

I cannot get to implement correctly neither of the two solutions given here. I just wanted to make a quick image from a "rows x columns" matrix, where the Y axis must be plotted in log scale. I thought it would be simple, but it seems matlab has so much complexity that my approach is not working.
