Draw Vertical Reference Line On Plot Matlab вђ Boredmonday Superimpose a least squares line on the scatter plot. refline. add a reference line at the mean of the scatter plot. mu = mean(y); hline = refline([0 mu]); hline.color = 'r'; the red line is the reference line at the mean of the data. Call the nexttile function to create the axes objects ax1 and ax2. then plot into each of the axes. add a dotted vertical line and label to each plot by passing the axes to the xline function. tiledlayout(2,1) ax1 =nexttile; x = linspace(0,10,200); y1 = cos(x); plot(ax1,x,y1) ax2 = nexttile;.
6 Graphing In Matlab Engineering Libretexts Line style and color, specified as a character vector or string scalar containing characters and symbols. the characters and symbols can appear in any order. you can specify the line style, line color, or both. marker symbols such as 'o' are ignored. example: ' g' is a green dashed line. Superimpose a least squares line on the scatter plot. refline. add a reference line at the mean of the scatter plot. mu = mean(y); hline = refline([0 mu]); hline.color = 'r'; the red line is the reference line at the mean of the data. If you can organize the x and y coordinates of your line segments into 2 by n arrays, you can use the function plot to plot each column of the matrices as a line. here's a simple example to draw the four lines of a unit square: x = [0 1 1 0; 1 1 0 0]; y = [0 0 1 1; 0 1 1 0]; plot(x,y); this will plot each line in a different color. Matlab draws a smoother graph −. adding title, labels, grid lines and scaling on the graph. 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. the xlabel and ylabel commands generate labels along x axis and y axis. the title command allows you to put a title on.
