So you build a horizontal bar chart showing some values over time...let's say by month. You start off building it with a discrete date, but you decide to show a trend line. Denied! You can't show a trend line with that discrete date. So you change it to a continuous date, you add your trend line without a problem, but then you realize the labels are not centered to the bar. And there is no way to center them. Argh!!!!!!! This blog post will help you solve this problem!
