Hi,
I have a data that looks like this (snippet) -
104.000000 128.599991 3876.100211 1921
98.199997 135.800003 2103.948191 1922
132.299988 135.199997 6265.961561 1923
I have made a heat map of this data using X Y and Z columns. I would now like to label only the points that fall in a certain region of the heat map. The labels may be taken from the 4th column. I have attached the heat map. Can someone please help me with this..

For instance in the image attached the plot is "labeled" with x and y co-ordinates. Similarly I want to label only the dark colored points with values appearing on the 4th column.
Basically I want to know the identity of only those points (in terms of values in the 4th column) that are darkly colored.

Which heatmap routine are you using? Knowing that might make it easier to figure out which points are "darkly colored"

For example,
mask = (X >= 50 & X <= 100) & (Y < 50 | Y > 250);
xm = X(mask);
ym = Y(mask);
Lm = cellstr( int2str(Labels(mask)) );
text(xm, ym, Lm);
