I want to include a vertical line on the histogram, so it shows the location of the mean. The mean value is 5.12, how can I modify this code?

subplot(2,1,1)
 histogram(LotH); 
 grid on;
 title("Graph of (LotH)");
 xlabel("LotH");
 ylabel("Scores");
  hold on;
 line([0,5.12], ylim, 'LineWidth', 2, 'Color', 'r');

xline() starting from R2018b https://www.mathworks.com/help/matlab/ref/xline.html

You are not plotting a vertical line. The coordinates you're using are (0,y_min) and (5.13,y_max), which is not a vertical line. You need to use this:

line(5.12*[1 1],ylim)

Or consider using the xline function (introduced in R2018b)

how can I include vertical dotted lines on histogram to show the cutoff of the outliers?

xline(LOCATION, ':')
