You cannot mix log coordinates If you attempt to add a loglog, semilogx, or semilogy graph to a linear axis mode plot with hold on, the axis mode will Whenever I try to create a figure using the command semilogy, the figure opens up but it's a blank page and it doesn't I'm having trouble plotting multiple figures using subplot and semilogy. Whenever I try to create a figure using the command semilogy, the figure opens up but it's a blank page and it doesn't This MATLAB function plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and a linear scale on the y-axis. Try semilogy() live — edit code, see output The semilogy function is plotting the y-axis on a logarithmic scale, but I think you can't tell because the data points are not separated I have a script with several semilogx plots -on OSX10. The reason is that you are using a logarithmic x -axis, and the unable to plot semilogy properly. Only the last figure appears in semilogy h = figure(2); for k = Hey, I sometimes notice that MATLAB refuses to plot in a logarithmic x- or y-scale, even though there are no zero or negative values MATLAB Answers semilogy, loglog do not work in order to set the y axis on a logarithmic scale 2 Antworten Why This is a bug in the documentation in MATLAB R13. If loglog () and semilogy () and semilogx () have no effect if "hold on" is already in effect for the axes. semilogx (Y) creates a plot using a base 10 Discover the art of creating stunning semilog plots in MATLAB.

I'm having trouble plotting multiple figures using subplot and semilogy. semilogx (Y) is equivalent to semilogx (real (Y), imag (Y)) if Y If you attempt to add a loglog, semilogx, or semilogy graph to a linear axis mode plot with hold on, the axis mode will remain as it is If you do not specify a color when plotting more than one line, semilogx and semilogy automatically cycle through the colors and line As you pointed out the semilogx function cannot work with x is 0. I loglog () and semilogy () and semilogx () have no effect if "hold on" is already in effect for the axes. The command ppval can be used to Here's the one from the semilogx page: Thesemilogxfunction plotsx-coordinates on a log scale by setting The official home of MATLAB software.
