Where would we be without charts? Not only are charts more appealing to our eye than raw data, but they also make it much simpler for us to spot trends. The old saying “a picture is worth a thousand words” also applies to charts. Managers don’t always want to look at every record in a spreadsheet; they would rather make their decisions based on trends, whether they be good or bad. By looking at trends, management can decide what actions the company should take in the future. Charts can summarize vast amounts of data and also show relationships between data. Charts make it easier to see such things as what lines of product are more profitable, what the most profitable time of year is, whether the profitability of the company is on the rise or going down, what departments are doing well and which are not, and on and on.
