linkdatatips

Creates and maintains linked datatips in all plots as the user moves around the first plot

Description

I often find myself trying to compare the results of different functions z=f(x,y), using datatips in the plots. This function provides a way of exploring results in one plot while observing values in the other plots as well. Linkdtatips works with plots formed by image, imagesc, mesh,meshc, pcolor, surf and surfc.

Added feature. To shift the primary datatip focus to the kth plot, call again as linkdatatips(hg(k))
 

Linkdatatips is compatible with linkaxes.

EXAMPLE:
z = peaks(50);
figure
h(1) = imagesc(z);
figure
subplot 121
h(2) = surf(z.^2);
subplot 122
h(3)=mesh(z+3);
linkdatatips(h);

Pretty nice. It's about time someone figured out how to do this. My one wish would be that it be possible to trigger a linked datatip from any of the plots in the set, and not just fig(1). That way I wouldn't have to relaunch the function and reorder the input handles everytime I need a different image to serve as the reference.

Very nice ! I need a helping hand from the author to modify the code such that it works also with imshow.

Is there a work-around to use this function with a regular plot/subplot? I have 4-5 subplots of data time-histories and I would like to link datatips between the plots. The data are in simple arrays and are currently plotted using subplot(5,1,X); plot(...)
