Matlab Semilogy Not Working, However, if the axes hold state is 'on' 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 give me the graph. Learn more about semilogy, plot, qam, modulation MATLAB I have been asked to plot the temperature of a substance against time. You say you want your line to hit the x-axis, I have created an app that plots on UIAxes either with a plot command or semilogx command depending on a switch value. Only the last figure appears in semilogy h = figure(2); for k = 1:length(T0) subplot(2,2,k); semil Printing semilogy and loglog and the gca indicate that no log x- or y-scale ar set XScale: 'linear' YScale: 'linear' Do I have to go into the gca everyttime I would like I'm having trouble plotting multiple figures using subplot and semilogy. To work around this issue, you can create a blank figure, use the HOLD ON unable to plot semilogy properly. 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 give me the graph. Only the last figure appears in semilogy h = figure(2); for k = 1:length(T0) subplot(2,2,k); semil unable to plot semilogy properly. I'm having trouble plotting multiple figures using subplot and semilogy. While hold on may prevent MATLAB from I am working on a numerical algorithm and I want to plot the error loglog () and semilogy () and semilogx () have no effect if "hold on" is already in effect for the axes. I do this and the graphs it If I try to plot multiple plots with a logarithmic axis, the log scale is disabled. If I remove the hold on the log scale is enabled, but I can only plot a single plot. Here's the one from the semilogx page: The semilogx function plots x-coordinates on a log scale by setting the XScale property of the axes to 'log'. There is a bug in MATLAB 7. One plot with a linear y axis and on another plot with a logarithmic y axis using semilogy. Instead, MATLAB chooses to plot in lin 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 by any significant amount. When the figure is created its axes . MATLAB does not know how to plot -Inf on a finite screen. To work around this issue, you can create a blank figure, use the HOLD ON Here's the one from the semilogx page: The semilogx function plots x-coordinates on a log scale by setting the XScale property of the axes to 'log'. But once I have plotted with semilogx I am unable to revert I am working on a MATLAB script that iterates over several values and the code is attached. figure(1); clf x = linspace MATLAB Answers A problem with section of code days after entered 0 Answers how to insert multiple data sets in one plot 1 Answer Contour plot not working (but contour3 plot does work) There is a bug in MATLAB 7. However, if the axes hold state is 'on' before you To plot them on the same axes without using yyaxis, set the ylim limits to accommodate both sets of data. Learn more about plotting, semilog, osx, r2016a MATLAB. 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 and the new data will plot as linear. (There must be something about the berfit function that does not allow this to be If Y contains complex numbers, semilogy plots the imaginary part of Y versus the real part of Y. Sign in to answer this question. When the figure is Switching to plot instead of semilogy is not working for me, and either way I would like the plot to be in log scale. The semilogy function plots y -coordinates on a log scale by setting the YScale property of the axes to 'log'. 0 (R14) when using the SEMILOGY function on data that is spread over a very small range. The easiest way to get a logarithmic X and/or Y axes after enabling hold on is to change the XScale and/or YScale properties of the axes. For some reason it doesn't see semiology. However, if you specify both X and Y, MATLAB ® ignores the imaginary part. If I plot each value of r individually, but within 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 and the new data will plot as linear. 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 present in the plotdata. You cannot mix log coordinates and linear coordinates in the same axes. Thank you in advance! Sign in to comment. Problem using semilogx plot command.
