Hi, I have a series of point plot as follows using a matrix Nx3 matrix

scatter(xp,yp,100,c,'filled')

with color that changes depending of values of a third column, which has the same lenght of xp and yp.

Is there a way to display even the numerical value of the third column near each points on the plot?

hello

you can use text for that job

xp = 1:0.5:2*pi+1;

yp = 0.1*xp+sin(xp);

c = rand(size(xp));

scatter(xp,yp,100,c,'filled') ;

xlim([0 8]);

for ci =1:numel(xp)

text(xp(ci),yp(ci)+0.1,num2str(c(ci),2))

end
