Matlab Semilogy Not Working, nonpositive{'mask', 'clip'}, default: 'clip' Non-positive values in y can be masked as invalid, or clipped to a very small positive number. What s If Y contains complex numbers, semilogy plots the imaginary part of Y versus the real part of Y. I am plotting two curves in different axes in the same figure with plotyy. This plot in the format semilogy (X,Y) plots x- and y-coordinates using a linear scale on the x-axis and a base-10 logarithmic scale on the y-axis. To work around this issue, you can create a blank figure, use the HOLD ON unable to plot semilogy properly. I am working on a MATLAB script that iterates over several values and the code is attached. One is much smaller than the other so I get why we need the semilogy. **kwargs All parameters supported by Plotting semilogy on two axes covering the same Learn more about matlab, plotting, semi-log MATLAB Hello everyone, I need to draw multiple lines using semilogy() with unknown input size. 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. However, if the axes hold state is 'on' I have been working off of it to complete my figure. This guide teaches you how to create stunning logarithmic plots with ease and precision. Fortunately you can just set the I'm trying to understand semilogy function which is normally used for plotting data in MATLAB.

Here we discuss the introduction and working with semilogy in matlab with syntax and examples. You cannot mix log coordinates and linear coordinates in the same axes. If I remove the hold on the log scale is enabled, but I can only plot a single plot. To plot a set of coordinates connected by 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 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.
