Autocorrelation plot with 95% confidence intervals for each sample

Dear All, When I ue autocorr(x, length(x)-1, numLags), it plots the autocorrelation of x, and the confidence intervals of the vector as two lines above and below 0. But what I need is a way to plot the autocorrelation of a x with the 95% confidence intervals of each autocorrelation sample (local confidence interval). Is there a way? Thanks
