I have a 2D plot. I plotted a curve and the average of the data in the same plot. I want to write the average value beside the Y-axis to indicate the average value. How to write it ?

@Jan Yes.. Using 'text' solve my problem. I inserted a value beside axis with 'text', then it was easily adjustable using plot edit options.

在 MATLAB Online 中打开

x = rand(1, 10);
m = mean(x);
axes('XLim', [1, 10], 'NextPlot', 'add', 'Box', 'on');
plot(x, 'b');
yline(m, 'g');
text(10.01, m, 'Mean', ...
    'Color', 'g', ...
    'HorizontalAlignment', 'left', ...
    'Units', 'data');
