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

this is the snap shot of the code and warning message i am getting

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

[Adam Danz]

datatip() was not released until r2019b.

Thank you Adam for this information,

Is there a way I can create datatip programatically in 2019a version by some other method.

[Adam Danz]

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.
