What is a Dynatable™?

Concept

This is a table of data that is dynamic—not static. It changes constantly as you view it to reflect the fact that the underlying data also is changing constantly—in this case over time. For example, every 15 seconds another American uses marijuana for the first time. If you were to view the dynatable™ in this section for a minute, you would see the marijuana totals increment by 4. If you accessed the dynatable™ 24 hours later the totals would show 5,760 more first-time marijuana users.

Printing Dynatables™

Despite the fact that the dynatable™ is constantly being updated, you may print it at any point in time. You will print the then current data together with the current time on which they are based. Print a dynatable™ the same way as you would any other Web material. Use the "PRINT" button on your browser as you usually would.

Saving Dynatables™

Dynatables™ and files containing dynatables™ can be saved just as any other material on the World Wide Web. However, when you do save a file containing a dynatable™, you will obtain a static table with the data that was in place at the exact time of the download and save. If you want more current data at a later time, you must access the dynatable™ on the Web again, and you will have the latest information.
