multiple datatip value extraction

i have plotted my graph and have marked certain peaks in the graph with datatips. now i would like to extract all the marked values to either work space or anywer else so that i can plot those data again. i'm using R2009b

Hi Kumaresan, You can get the values of datatip positions using the datacursormode and getCursorInfo functions:

d = datacursormode(fig);
vals = getCursorInfo(d);

where fig is the handle to your figure and vals is a structure containing positions and data indices.

[kumaresan]

this is the comand i use to plot

h=semilogx(t1fft1hz,t1fft1g),

then i placed 5 datatips on my graph.

then i entered,

d = datacursormode(h);

vals = getCursorInfo(d);

mathlab showed,

??? Error using ==> datacursormode at 138

Invalid figure handle

wher did i went wrong?

datacursormode() must be applied to a figure as a whole, not to a plot within a figure.
