I am trying to figure out how to update a custom datatip. The process is straight forward if it was for a regular plot however, when using a GUI figure it seems like that callback function does not update. I tried adding the following lines of code to the existing Callback function but was not successful.
dcm_obj= datacursormode (gcf);
datacursormode on
set (dcm_obj,'updatefcn',@myfunction)
where myfunction is the custom function that I am using to customize the font/color etc...
I would apperciate any suggestions.
Thanks in advance.

No static would be enough. I would like to custom the blue color on the text given in the image attached to black.

The update function callback is only applied to new datatips, or datatips that are moved. (I am not certain at the moment whether it is called if the axes resizes.)

Ah I see. Everything works now when I deleted the old datatips and added new ones. I was under the assumption it auto updates which is not the case. Well thanks alot for your help !
