Adding field comments in dataset

When working with big data, it can be very helpful to have access to comprehensive field-level descriptions. In CDP Data Visualization, you can use field comments to provide the context and meaning of each dataset field.

The following steps demonstrate how to add description to a column of a dataset, as a 'comment'. In this example, we are using the column iso_cc (the ISO-compliant country code) in the dataset World Life Expectancy [data source samples.world_life_expectancy].

  1. On the main navigation bar, click Data.

    The Data view appears, open on the Datasets tab.

  2. In the left navigation menu, click samples.
  3. In the Datasets area, select World Life Expectancy (samples.world_life_expectancy).
  4. In the Dataset Detail menu, select Fields.
  5. In the Fields interface, select Edit Field.
  6. Under Dimensions, find the field iso_cc, and click the down arrow icon on the right.
  7. From the menu, select Edit Fields.

    The Edit Field Parameters window modal appears.

  8. Under Field Comment, add the following text:
    ISO 3166 Country Code Standard, Numeric, described in Mappings are at
  9. Click Apply.
  10. Under Dataset: World Life Expectancy, click Save.
  11. Click Show Comments.
  12. To hide column comments, click Hide Comments.
