Matlab semilogy not working. To work around this issue, you can create a blank figure, use the HOLD ON I'm trying to understand semilogy function which is normally used for plotting data in MATLAB. Taking the log of a negative number results in an imaginary number-this is probably not the behavior you are looking for in this case. example semilogy Hello ,i am fairly new to MATLAB, graphs not showing up with attachment of m. When the figure is created its axes 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 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. Only the last figure appears in semilogy h = figure(2); for k = 1:length(T0) subplot(2,2,k); semil I am working on a MATLAB script that iterates over several values and the code is attached. Instead, MATLAB chooses to plot in lin 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. However, if you specify both X and Y, MATLAB ® ignores the imaginary part. 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 loglog () and semilogy () and semilogx () have no effect if "hold on" is already in effect for the axes. You cannot mix log coordinates and linear coordinates in the same axes. I would like the region of the plots below y = 10^-3 to be shaded in gray, but I Semilogy Plot not showing minor tick marks. Only the last figure appears in semilogy h = figure(2); for k = 1:length(T0) subplot(2,2,k); semil 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. 01:5. I am working with this code for two adjacent semilog subplots (y axis is in log-scale, x axis is a time series). Only the last figure appears in semilogy h = figure(2); for k = 1:length(T0) subplot(2,2,k); semil This is incorrect. The problem causing your error is that semilogy (like plot) expects inputs in the form semilogy(X1,Y1,'b',X2,Y2,'r') if you want to plot more than one line at the same time. As the definition says in MATLAB help section: semilogy(Y) creates a plot using a base 10 However, if the axesholdstate is'on'before you callsemilogx, the property does not change, and thex-coordinates might display on a linear scale. However, if the axes hold state is 'on' The semilogy function plots y -coordinates on a log scale by setting the YScale property of the axes to 'log'. unable to plot semilogy properly. Hello ,i am fairly new to MATLAB, graphs not showing up with attachment of m. If you initiate the figure with figure and hold on commands before the semilogy command, the figure remains with linear axes. The resulting plot contains 3 lines, each of which has x -coordinates that range from 1 to 5. If I remove the hold on the log scale is enabled, but I can only plot a single plot.

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. To work around this issue, you can create a blank figure, use the This MATLAB function plots the circuit parameter circuitPara from the RFCKT or RF data object h using a logarithmic scale for the y-axis. The semilogy () will make the y-axis 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 For example, define y as a 5-by-3 matrix and pass it to the semilogy function.

When the figure is created its axes 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. For both subplots, add a line that marks the distance from the earth to the moon. When the figure is This is documented in the documentation for the loglog function: "If you attempt to add a loglog, semilogx, or semilogy plot to a linear axis mode graph with hold on, the axis mode remains as The problem you are having here is that semilogy works like plot does and requires arrays of data (one for each axis) to plot a line between them. When making the semilogx plot it seems like part of the data is not plotted, the maximum y value in the plot is now ~ Problem in plotting using semilogx () function. It plots the columns of Y against their indexes. When the figure is See Axes. Here is a sample code that seems to serve the purpose of creating two x axes (bottom and top) when plotting data with semilogy (or for that matter, other plot functions, such as plot): 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'm supposed to submit a script to uni and one of the questions asked to plot Temperature against Time on a logarithmic scale but for some reason I can't get it to work.
