在 MATLAB Online 中打开

you can move the text every now and then by changing the coordinates. e.g.

data=randi(42,100,1);
m=mean(data);
plot(data);
yline(m);
tx=text(1,1.1*m,'some text','Color','r');
for xCor=2:80
    tx.Position=tx.Position+[1 0 0];
    pause(0.1)
end

在 MATLAB Online 中打开

tx=text(x(1),1.1*y(1),'lead');

creates the text label 'lead' near x(1) and y(1). i used 1.1*y(1) to be sure that the label is not exactly on the point of the curve i want to label but a bit above

similarly i use a slightly bigger y when i move the label according to the further points of the curve
