%> This hachure typically represents confidence intervals, prediction intervals, or standard deviations.
%>
%> The hachures interfere with the line width of the axes and legend border - weird but this is a MATLAB's problem
%
%> @param xaxis
%> @param intervals must be a [2]x[number of points] vector with one interval in each column, where the first element is the lower value
%> @param color
