For example, plot two lines and a scatter plot. Then reset the hold state to off. x = linspace (0,10,50); y1 = sin (x); plot (x,y1) title ( 'Combine Plots' ) hold on y2 = sin (x/2); plot (x,y2) y3 = 2*sin (x); scatter (x,y3) hold off. When the hold state is on ... Oct 19, 2021 · Answers (3) You are on the right track. You can use polyfit to fit a trend line to the data. The output of polyfit is a vector of coefficients corresponding to the polynomial you fit to the data. You can then use polyval for those coefficients to create the trend-line to add to the plot. Your x-data for polyfit will be the dates, and the y-data ...

To add text to multiple points, specify x and y as vectors with equal length. text (x,y,z,txt) positions the text in 3-D coordinates. example.1 Answer Sorted by: 3 That's usually done by annotation, and I think it is done manually. Since you have a lot of graphs and not much space, I suggest you use text to add the label at the end of the line. So in the loop add (under ylabel for example) str = sprintf (' n = %.2f',n); text (x (end),H (end),str); This will result in
