you have to know the xy coordinates of those points to mark them . suppose i have a graph Y(X) : X=1:10;Y=randn(1,10); plot(X,Y), holdon, Marked=[X(2) Y(2); X(4) Y(4)]; plot(Marked(:,1),Marked(:,2),'o'); 댓 8
So basically, I made a graph by using the value of X and y (not Y) and my professor asked us to import the data points as well to show the regression coeeficient. However, I don't know what the data points is and how to import the data points and plot the line at the same ...
Add a title and y-axis label to the plot by passing the axes to the title and ylabel functions. Repeat the process to create the bottom plot. Get % Create data and 2-by-1 tiled chart layout x = linspace(0,3); y1 = sin(5*x); y2 = sin(15*x); tiledlayout(2,1) % Top ...
This MATLAB function adds a text description to one or more data points in the current axes using the text specified by txt.
Add Text to Multiple Data Points Copy Code Copy Command Plot a line. Add the same text to two points along the line. Get x = linspace(-5,5); y = x.^3-12*x; plot(x,y) xt = [-2 2]; yt = [16 -16]; str = 'dy/dx = 0'; text(xt,yt,str) Add different text to ea...

plot(X,Y) creates a 2-D line plot of the data in Y versus the corresponding values in X. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of...
Use the scatter function to draw a scatterplot, specify the size of the dots to be 30 points, the fill color is turquoise, and the outline color is magenta. (3) 指定一系列绘图中的颜色 (3) Specify the colors in a series of plots ...
plot(x,y1,'--go',x,y2,':r*') Plot Only Data Points This example shows how to plot only the data points byomitting the line style optionfrom the line specification string. Define the dataxandy.Plot the data and display a star marker at each data point. ...
plot(sfit) plots the surface given in the sfit object sfit over the range of the current axes (gca). If no current axes exist, the function plots the surface over the range of the data used to create sfit. example plot(sfit,[x,y],z) plots sfit together with a scatter plot of the...
