PS Ch. 8--"Options, Options, Options"

There is a humongous variety of chart options, for instance: column, bar, line, pie, scatter, area, doughnut, radar, surface, bubble, stock, cylinder, cone, and pyramid. They give you so many different options for good reasons. First it all depends on the data. If you have data tables were you are comparing seasons to sales you might need a column chart? Second you might have more than one form of data in your data table. Like you have a certain amount of days, and different plants that you are watching grow, because you added different amounts of water to them you might need a scatter chart. Last it depends on what you want to learn from the data. Say you want to know which country has a higher population then you might need a pie chart. They give you a variety of charts for a reason not just to show how many different designs of charts you can have.
