Since I took a little poke at charting in my REPT post (or maybe I took a poke at morons, I’m not sure), I feel obligated to provide you with some real charting information. Unfortunately, my charting skills are quite lacking. But fellow MVP Jon Peltier is a charting wiz. If you’re interested in charting, his website is a must bookmark.
If you’re more into the printed page, check out John Walkenbach’s Excel Charts. Guess who the Technical Editor was for that book. John’s excellent writing style combined with Jon’s knowledge of charting is a can’t-miss combination.
