How to insert a Data Cursor on a specif location from command ?

Hello,

I have done some plots and I need to insert a Data Cursor to "highlight" the maximum of a curve.

Of course I could do it from the plot itself, but it would be better to do it automatically from the .m script.

Do you know how to d it ?

Thanks a lot, Bastien

Update: as of r2019b you can use datatip(__) to programmatically place a data tip.

Demo:

fig = figure(); 
ax1 = subplot(1,2,1); 
h1 = plot(magic(5));
datacursormode on
datatip(h1(2), 2, 5);

subplot(1,2,2)
h2 = plot(rand(10), 'sb');
datatip(h2(3),'DataIndex',5);

Is it possible to have multiple data cursor points in the same plot through programmatically?

Yes, call datatip() as many times as you'd like.
