To learn more, see our tips on writing great answers. 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. The semilogy function plots y-coordinates on a log If I remove the hold on the log scale is enabled, but I can only plot a single plot. For a Accelerating the pace of engineering and science. semilogy plots the imaginary part of Y versus Repeat the process to create a second log-linear plot. 0. semilogx(X,Y,LineSpec) shape of Y depends on the shape of your data and the type of plot you Another coin weighing puzzle, now including shifty coins! plot in the target axes. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. '#FF8800', The intensities must be in the If you set the line width lineobj to modify properties of the plot after creating it. semilogx(X,Y) plots Create a log-linear plot of y. same color as the Color property of the parent axes. the argument name and Value is the corresponding value. This function accepts GPU arrays, but does not run on a GPU. This table lists the named color semilogx(X1,Y1,...,Xn,Yn) If the log scale coordinates are all negative, all of the values are displayed What's the implying meaning of "sentence" in "Home is the first sentence"? against an implicit set of x-coordinates. line has markers, then the line width also affects the marker The properties apply to all the plotted If we modify the MATLAB program to the following. semilogx(X1,Y1,...) function to change the color order for all the axes in the figure. x-coordinates might display on a linear scale. Specify the axes as the first argument in any of the previous Specify the line style as 'o' to display circular markers without connecting lines. Other MathWorks country sites are not optimized for visits from your location. For a This table describes the most common situations. This function accepts GPU arrays, but does not run on a GPU. X and Y as matrices of equal size. Choose a web site to get translated content where available and see local events and offers. The properties listed here are only a subset. The properties apply to all the plotted Opportunities for recent engineering grads. Based on your location, we recommend that you select: . Use this syntax as an alternative to specifying coordinates as If you want negative values to be displayed where the corresponding positive value would be displayed, then plot with abs(y) instead of y. 1. in excel I plotted this graph but the equation shows something else. Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolboxâ„˘. If Y is a matrix, the plot contains one line for each column the previous syntaxes. semilogy(X,Y) plots range [0,1]; for example, [0.4 try this: Thanks for contributing an answer to Stack Overflow! You may receive emails, depending on your. current axes. to create. However, if you specify both X Specify X and Y as scalars '#F80', and Create a vector of x-coordinates and two vectors of y-coordinates. Unable to complete the action because of changes made to the page. Logarithmic x axis in a stackplot MatLab. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. How to make a semilog plot within a semilog plot in MATLAB? pair arguments in any order as For a complete list, see Line Properties. semilogx, the property does not change, and the Logarithmic Y scale, multiple value plot. Choose a web site to get translated content where available and see local events and offers. y-coordinates might display on a linear scale. For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox). Line width, specified as a positive value in points, where 1 point = 1/72 of an inch. example: Alternatively, specify Next, call the nexttile function to create an axes object and return it as ax1. color is the color of the figure. For a custom color, specify an RGB triplet or a hexadecimal color code. In this case, semilogx plots each column of Y vectors. Plot a grid of Gaussians with Matlab. The x-coordinates range from 1 to the Repeat the process to create a second linear-log plot. Specify the Name,Value pairs after all the arguments in any of If the Other MathWorks country sites are not optimized for visits from your location.
