![]() Let's assume that we want to plot the following elegant exponential and sinusoidal function: let's draw a simple discrete function % Avoid superimposed operations and close previous figs. 'stem' does not join the circles with a line, and it is very helpful to stress the fact that the function is not continuous but discrete. It draws vertical lines (with a little circle at the tip) proportional to the value of the function at that particular horizontal value. In this example, we study the 'stem' instruction to plot Matlab functions. H = stem(.) returns handles to line graphics objects Examples Create a stem plot of 10 random numbers. Stem(.,LineSpec) specifies the line style, marker symbol, and color for the stem plot. stem(.,'fill') specifies whether to color the circle at the end of the stem. When I plot any of the examples from the website, all the lines have a gradient color on them, which makes my dataset confusing. Additionally, X can be a row or a column vector and Y a matrix with length(X) rows. Learn more about stem, color, 2016a MATLAB I am trying to do a stem plot with all the lines the same color. X and Y are vectors or matrices of the same size. Do a stem plot of these points, and store the. stem(X,Y) plots X versus the columns of Y. Matlab: Create an x vector that has 30 linearly spaced points in the range from 2p to 2p, and then y as sin(x). When Y is a matrix, stem plots all elements in a row against the same x value. ![]() stem(Y) plots the data sequence Y as stems that extend from equally spaced and automatically generated values along the x-axis. A circle (the default) or other marker whose y-position represents the data value terminates each stem. A two-dimensional stem plot displays data as lines extending from the x-axis.
