  x    <- list(rnorm(42), rnorm(42)+2)
  br   <- seq(-3, 5, length=13)
  cols <- c("#1D267B", "#ceffc0")
  histStack(x, breaks=br, col=cols)

  histStack(x, breaks=br, col=cols,
            midsFun=function(z) {
              z <- paste(round(z, 3))
              z[seq(2, length(z), by=2)] <- NA
              return(z)
            } )
