Create data tips at multiples points on a figure programatically

I have a matrix "MyData" with size 592 by 1. After plotting I want to place datatips at 2 points. How can I create datatips programatically?

My code is

figure (1)
plot(MyData)

X_r1 = ((l +0.15)*8)/0.05  % X_r1 and X_r2 are calculated from 'l' which I input while running the code
X_r2 = (((l +0.15)*8)/0.05) + ((2*l+0.15)/0.05)

I want to crate datatips at X_r1 and X_r2! How can I create? Thank you.

h = plot(MyData);

X_r1 = ((l +0.15)*8)/0.05  % X_r1 and X_r2 are calculated from 'l' which I input while running the code
X_r2 = (((l +0.15)*8)/0.05) + ((2*l+0.15)/0.05);

dcm_obj = datacursormode();
createDatatip(dcm_obj, h, [l, X_r1]);
createDatatip(dcm_obj, h, [l, X_r2]);
