![]() Where, m and n are the number of rows and columns of the plot array and p specifies where to put a particular plot.Įach plot created with the subplot command can have its own characteristics. The subplot command is used for creating subplots. ![]() When you create an array of plots in the same figure, each of these plots is called a subplot. When you run the file, MATLAB generates the following graph − Generating Sub-Plots The following example shows this − Example After the getting plot and x & z axes converted into log scale, colorbar is not changing. You can provide minimum and maximum values for x and y axes using the axis command in the following way − I am trying to plot a 3d surface which has two axes in log scale. The axis command allows you to set the axis scales. When you run the file, MATLAB generates the following graph − Setting Axis Scales #Matlab log plot code#The following table shows the colors and their codes − Code MATLAB provides eight basic color options for drawing graphs. MATLAB generates the following graph − Setting Colors on Graph The following example demonstrates the concept − Example You can draw multiple graphs on the same plot. MATLAB generates the following graph − Drawing Multiple Functions on the Same Graph ![]() The axis square command generates a square plot. The axis equal command allows generating the plot with the same scale factors and the spaces on both axes. The grid on command allows you to put the grid lines on the graph. The title command allows you to put a title on the graph. The xlabel and ylabel commands generate labels along x-axis and y-axis. MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph. MATLAB draws a smoother graph − Adding Title, Labels, Grid Lines and Scaling on the Graph Please note that as we decrease the increment, the graph becomes smoother.Ĭhange the code file a little, reduce the increment to 5 − In this example, we will draw two graphs with the same function, but in second time, we will reduce the value of increment. Let us take one more example to plot the function y = x 2. You can also plot multiple variables and matrices with. Output: In the above figure, only the x-axis is in the log scale of base 10. a 1:100 b 2a lg semilogx(a,b) grid on axis tight. When you run the file, MATLAB displays the following plot − If you want to plot the variables on the x-axis of base 10 log scale and y-axis of linear scale. Let us plot the simple function y = x for the range of values for x from 0 to 100, with an increment of 5.Ĭreate a script file and type the following code − ![]() ![]() For more examples, go to MATLAB Plot Gallery - Cite As MathWorks Plot Gallery Team (2022). Read about the 'loglog' function in the MATLAB documentation. #Matlab log plot how to#For example, you can use a command like this: plot main.To plot the graph of a function, you need to take the following steps −ĭefine x, by specifying the range of values for the variable x, for which the function is to be plottedįollowing example would demonstrate the concept. This is an example of how to create a log-log plot in MATLAB. However, you can set a explanation other parameters that are included in the function. The good news is that in the previous version of Matlab, the arguments to the function were set in a completely separate file. However, if the axes hold state is 'on' before you call loglog, those properties do not change, and the plot might display on a linear or semilog scale. trend The loglog function plots coordinates on a log scale by setting the XScale and YScale properties of the axes to 'log'. How To Plot A Log Function In Matlab You already know that Matlab shows you a lot of high-level functions in a single file. Log-log scale plot - MATLAB loglog - MathWorks. ![]()
