Custom Display Formats for Large Numbers

Distinguishing Between Scientific and Currency Unit Abbreviation

The following steps demonstrate how to adjust the display format for currency, using the S format option. We are using the Capital Expenditure by Industry dataset, based on datafile annual-capital-expenditure-industry.csv.

1. Create a new Bars visual on the dataset Capital Expenditure by Industry.
2. Place the industry field on the X Axis shelf, and expenditure field on the Y Axis shelf.
3. Change the expenditure field in the Display Format: Currency interface to display the $ (dollar) currency symbol, and click Save.

4. Click Refresh Visual, and note the display of numbers on the axis scale and in the tooltips.

   Obviously, the standard currency form is inadequate for representing very large numbers and quickly seeing the difference in their magnitude. If the visual type was a table, it would be much harder still.

   

5. Change the expenditure field in the Display Format: Custom Formats interface by setting the value of Customize Date/Time to $,S (currency, ',' thousands separator, and 'S' for currencies). Click Save.

6. Click Refresh Visual, and notice that the new display format more clearly categorizes the magnitude of the currency, with Educational Services expenditure valued at approximately $226 Billion, contrasting with Manufacturing at nearly $2 Trillion, for the years covered by the data.

   

7. [Optional] You can see how the data format appears across the data set by creating a dashboard that contains both this bar chart and a table visual.

   • Clone the visual and change the chart type to table.
   • Name and Save that visual.
   • Click New Dashboard, and add both visuals to it.
   • Name and Save the dashboard.

   Note that some column values have the suffix B (billions), while larger columns have the suffix T (trillions).
