Applying labels to specific data points
显示 更早的评论
I have a scatter plot of x = [0 1 2] and y = [8 7 6] with corresponding labels in N = ['A', 'B', 'C']. I know how to add labels to all the data points using the text() or labelpoints() functions but I was wondering if there was a way to apply labels to certain data points only, e.g. (1,7) and (2,6)?

Share the (relevant) code you currently have so we know what to work with.
Also, what is labelpoints? If you're using non-bundled functions, it helps to say so.

If you're already using text, just throw an index into the mix... Assuming you have:
text(x,y,N);
Change it to:
N = ['A';'B';'C']; % If "N" is not cellstr or string datatype, must be column vector
labelinds = [2,3];
text(x(labelinds),y(labelinds),N(labelinds));

Objects returned by the text function have a 'Color' property. I doubt you can set each one to a unique color in a single call to text, but you can loop through the output afterward.
htext = text(...);
C = [1,0,0; ... red
0,1,0]; % green
for itext = 1:length(labelinds)
htext(itext).Color = C(itext,:);
end
