datalabel

Interactive labeling of data points on a plot.

Description

Have you ever looked at a plot and said "what's the value of the curve at this point?" Were you frustrated that gpinut only told you where you clicked, not the actual data value?

Well, worry no more! With datalabel, a single click on a line labels the point with its (x,y) coordinates. But wait, there's more! You can label as many points as you want, on as many lines as you've got. You can move the labels. You can add markers to the labels. You can even delete the labels.

So, don't delay. Download datalabel now, before supplies run out!

Simply superb! great work.

[Wong Yew Leong]

Cool...just what we wanted!

[Andrey Loginov]

Cool and easy to upgrade!
If you wish to get optional label backgrounds, text size, text color&style or even optional label position simply change input, store additional fields with "setappdata" and get them further with "getappdata".
It is also not difficult to modify code to get labels in between of XY line data points:).

Dear all,
I have a curve in 2d. Every point of this curve is correspond to another rows of a (n,3) matrix.
Is it possible with "datalabel" or do you know any other hint?
Thanks

For time series data you can get the 'x coordinate' as a date string by changing line 89 to ...
th = text(xv,yv,[' (' datestr(xv) ',' num2str(yv) ')']);

When you click on a feature it will tell you when it happened as a date and time rather than a cryptic matlab date number. One area where Excel seems to be better than Matlab (until now!).
