Wayne: What's crowded are my x axis labels. The bars look fine on my graph but the labels are being displayed from 29 to 170 one by one. I need something like a seq(29,170 by:10) or something like that. I don't want to treat my FL as factor because I don't want a bar per each FL value, I only want to count the number of FL at any given FL size. Thanks
