Say, for instance, that you're interested in whether a particular set of values is significantly different from zero. Get More Info When error bars are added to a data plot, the error data is output to a new column on the source worksheet.

When X is a 2D array, the i-th row of Y contains the percentiles p(i). Not the answer you're looking for? For a list of properties, see Errorbar Series Properties. Do not display the line that connects the data points by omitting the line style option for the linespec input argument.x = 1:10:100; y = [20 30 45 40 60 65
