Visual Analytics: How Catwoman Influenced My Data
A format is a way to change how your data appears in a chart or table. You can think of a format like a costume. For instance, even if I had a Cat Woman costume, it would not suddenly empower me with any special powers other than looking similar to her. You wouldn’t find me thinking I had new agile jumping abilities or for that matter deciding to embark upon a criminal enterprise with my new friend the Joker. So the costume would make me look different, but inside I’m still just a geeky SAS programmer.
Think of a format the same way (this is an important concept litter mates!) Your underlying data does not change because you changed the format. For instance, using the same example from last week,here is my data. The data item, Arrival Date (Original), is the true value; it shows the calls per minute. There were several ways to change the data item so it could appear as more than one superhero (or date value). Actually I guess CatWoman was super villain not a hero.
