Hello all, i would like to ask you if there is any way to count/print in a graph the number of points that are out of the range of y axis. I use like ylimit the mean value of my points +-3 standard deviations
ylimit([(mean-3*std) (mean+3*std)])

Thanks in advance,
Kostas

How about
yMean = mean(y(:));
yStd = std(y(:));
numberOutsideRange = sum(y<yMean-3*yStd) + sum(y>yMean+3*yStd) ;

This is just the number of points, a scalar, so I'm not sure what kind
of graph you were thinking of to graph it.
