Because a spreadsheet timeline can contain millions of rows of data, analysts may simply underutilize this method of analysis fearing being overwhelmed. Even if a massive spreadsheet was sorted and filtered for review, the time spent can be intensive. However, I know of no better method of showing the chronology of events than a timeline.

Charts and graphs created in spreadsheet applications are an effective means to visualize massive amounts of data. Using data in a particular spreadsheet, charts and graphs can be updated as information is updated. Visual representations of data may make it easier to comprehend the nuances of relationships between events. The visual impact of a chart as compared to a listing of information is shown in Figures 1.9 and 1.10. Figure 1.9 is an example of internet history shown in a spreadsheet that includes the number of visits per web site. Creating a chart of this data gives a clearer picture of the differences of web site visits as seen in Figure 1.10.
