Not able to create datatip

Hello all,
I am trying to create a datatip for my plot at a specific point.
my example code is-
x= (1:10);
y = x;
p=plot(x,y);
Whenever I am using- datatip(fig,x,y)
I am getting a warning message- This function is no longer supported. I am using 2019a version.
My second option was to use this-
dcm_obj = datacursormode();
createDatatip(dcm_obj,p, [x(2),y(2)]); But it doesn't show me the correct info instead of creating a datatip at 2nd x and y point it is creating dattip at first point of x&y.
Is there any way this problem can be resolved.
Thanks

The warning you're seeing is probably something left over from an older undocumented version of datatip() prior to it being released in r2019b.

datatip() was not released until r2019b.

I don't know a method to programmatically place a datatip prior to r2019b.
You could use a text object. Method #5 in this answer is a more elaborate example than the demo below.
x= (1:10);
y = x;
p=plot(x,y);
hold on
txt = sprintf('x = %g\ny = %g',x(2),y(2));
th = text(x(2)-.1,y(2)+.1,txt,'BackGroundColor','w','EdgeColor','k',...
'HorizontalAlignment','right','VerticalAlignment','Bottom');
ph = plot(x(2),y(2),'ko','MarkerFaceColor','c');

You could search the forum for undocumented methods of setting data tips prior to r2019b.
