Learn more about plotting 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. If I plot in the following way, I am working on a MATLAB script that iterates over several values and the code is attached. How to fix the semilogx function for figure 5. The data that it I'm trying to graph prints correctly in the workspace and the graph prints with the correct axis labels but my data unable to plot semilogy properly. If you do not specify a color when plotting more than one line, semilogx and semilogy automatically cycle through the colors and line styles in the order specified by the current axes ColorOrder and I have to plot two different electrical RTG outputs on a log linear graph but am stumbling on the plot. 4 (R2007a) to include the following statement in the help for LOGLOG, SEMILOGX/SEMILOGY function: MATLAB Answers A problem with section of code days after entered 0 Antworten how to insert multiple data sets in one plot 1 Antworten Contour plot not working (but contour3 plot does In the PLOTYY function I specify ‘semilogy’ as an argument to produce the graph with logarithmic scales for the y-axis. Quite simply, both plots are semilogx, although the range of x values isn't 10^0, 10^1, etc, as is on the bottom plot (which is what I desire), and the 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. For some reason it doesn't see semiology. If Y contains complex numbers, semilogy plots the imaginary part of Y versus the real part of Y. The reason is that you are using a logarithmic x -axis, and the first point has x =0, so the logarithm is −∞. The work also had to be done by hand and my code is outputting all the numbers I got with the equations. Unable to complete the action because of changes made to the page. The semilogx function plots x-coordinates on a log scale by setting the XScale property of the axes to 'log'. If you move the hold command after the first call to semilogx, it should work The hold on command is the culprit you're issuing it before you plot, so the linear axis is being held throughout. 6k次，点赞14次，收藏6次。当MATLAB的loglog或semilogy函数不显示对数坐标时，可能是因为`holdon`语句的位置不当或者数据点差异过小。解决办法是将`holdon`语句移 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.

If I plot each value of r individually, but within the script This MATLAB function plots x- and y-coordinates using a linear scale on the x-axis and a base-10 logarithmic scale on the y-axis. This is a guide to Semilogy Matlab. But once I have plotted with semilogx I am unable to revert I'm trying to use "semilogx ()" in my code but it's not working. In your situation it would be good to If you do not specify a color when plotting more than one line, semilogx and semilogy automatically cycle through the colors and line styles in the order specified by the current Axes ColorOrder and unable to plot semilogy properly.

MATLAB Answers A problem with section of code days after entered 0 Risposte how to insert multiple data sets in one plot 1 Risposta Contour plot not working (but contour3 plot does work) I'm trying to understand semilogy function which is normally used for plotting data in MATLAB. As you pointed out the semilogx function cannot work with x is 0. 1:10; subplot (1,2,2); I am working with this code for two adjacent semilog subplots (y axis is in log-scale, x axis is a time series). This bug was fixed in MATLAB 7. I tired different method to have y-axis in log scale but all of them are having linear results. Only the last figure appears in semilogy The hold on command is the culprit you're issuing it before you plot, so the linear axis is being held throughout. Is it working correctly for simpler data that doesn't involve all the file I have a CSV file which includes three columns. I have a problem with semilogx command. Please help this semilogy error message.

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. Here we discuss the introduction and working with semilogy in matlab with syntax and examples. I am trying to plot using semilog and want to plot BER in log scale but its not working. produces this nice figure, with the FaceAlpha feature working The same code but changing plot with semilogx in both commands produces with unable to plot semilogy properly. 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. for e. I have been working with my code, earlier it plotted fine the BER curve with semilogy but now when I added another case to semilogy it plots the curve fine but the it doesn't show the grid lines of semilogy.

Sign in to comment. semilogy (Y,LineSpec) Hi there, I have code here to analyse some data, I need two of the plots in a semi-log scale on the x-axis. 3. I want all the plots to figure on one same figure. However, if you specify both X and Y, MATLAB ® ignores the imaginary part. Sign in to answer this question. loglog () and semilogy () and semilogx () have no effect if "hold on" is already in effect for the axes. Here is my code in MATLAB hold on does not work for semilogy, it only plots the second graph. I am working on a numerical algorithm and I want to plot the error for 5 different shape parameters of my function. Learn more about semilogy, plot, qam, modulation MATLAB This MATLAB function plots x- and y-coordinates using a linear scale on the x-axis and a base-10 logarithmic scale on the y-axis. 31 Learn more about semilogx function and graphing help with nan MATLAB The hold on command is the culprit you're issuing it before you plot, so the linear axis is being held throughout. Your code works already in octave (and I don't have matlab at this computer), but I think the problem is that you do hold on before the first plot, hence preventing the initial axis to be created. Any help appreciated. example semilogy 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. Reload the page to see its updated state. I suppose it can therefore also not interpolate between log 0. You cannot mix log coordinates and linear coordinates in the same axes. I basically want to read the first two columns and then draw a semilogy plot with the values. To work around this issue, you can create a blank figure, use the HOLD ON loglog () and semilogy () and semilogx () have no effect if "hold on" is already in effect for the axes. loglog function displays tthe same result too. Learn more about semilogy, log As you can see, it does not work, the y axis does not have a logarithmic scale. g. However, if the axes hold state is 'on' before you call semilogx, the property does If Y contains complex numbers, semilogy plots the imaginary part of Y versus the real part of Y. This MATLAB function plots x- and y-coordinates using a linear scale on the x-axis and a base-10 logarithmic scale on the y-axis. I have the following loglog () and semilogy () and semilogx () have no effect if "hold on" is already in effect for the axes.
