Matlab plots can display data-tips but these cannot be interactively moved except to the 4 corners of the data point.
This utility enables the user to interactively drag any newly-created data-tip, anywhere in the Matlab figure. A dashed line connects the dragged data-tip with the original data point.
The new draggable functionality only affects new data-tips, so it can be turned on/off to enable standard and new data-tips to co-exist in the same plot (see screenshot).
Syntax: draggableDataTips(newState)
Examples:
draggableDataTips('on') or draggableDataTips(true) turns the new functionality ON for new data-tips.
draggableDataTips('off') or draggableDataTips(false) turns the new functionality OFF for new data tips.
Warning:
Relies on undocumented functionality.
This utility fails in HG2 (R2014b+) - please don't bug me about it, unless you found a solution...
On HG2 (R2014b+), use Allen's submission: https://www.mathworks.com/matlabcentral/fileexchange/69799-dragdatatip

Yair,
Just wanted to pass along a solution for allowing draggable data tips on newer versions of MATLAB (see attached link).

Aditya - a new version was just uploaded that fixes this minor problem.
Yair,
I like this a lot. Thanks.
I found what could be a bug:
- create a datatip
- drag it so that the dashed line appears
- click on the dashed line and an error appears and the datatip goes away.
This is in 2013b 64 bit.
Here is the error:
err =
