MAKEDATATIP

Allows programmatically adding datatips to any valid graphical object.

Description

MAKEDATATIP allows programmatically adding datatips to graphical objects.

Creation of this function was motivated because I was unable to find any simple built-in method. If there is a better method, I would love to know about it.

Note that this function was only tested in R2007b.

Example:
  x = 1:10;
  y = rand(1,10);
  hPlot = plot(x,y);
  makedatatip(hPlot,[3 8])

Example:
  [X,Y,Z] = peaks(30);
  hObj = surf(X,Y,Z);
  I = [5 8; 20 12; 22 28];
  hDatatip = makedatatip(hObj, I);

• MATLAB release: MATLAB 7.5 (R2007b)

A nice idea. Good help, lots of examples, good error checking, an H1 line. Well done.

Very useful! Sometimes, it's hard to find and select exactly the point, especially for 3-D complex surface.

Just what I was looking for on the Newsgroup a few months ago. Works perfectly on 2006b as well.
Thanks!

Very useful indeed. I don't know why Matlab itself doesn't provide this feature, I spent a lot of time searching the documentation for a way to do this.
