Hiding dataset fields from applications

You may find it useful to hide dataset fields that are not typically used for visualizations to prevent unintended bias in BI and analytics, or even to obscure confidential data. In CDP Data Visualization, you can do this by turning off the default visibility option of a particular dataset field.

The following steps demonstrate how to prevent data fields from appearing in visualizations and applications of dataset World Life Expectancy [data source samples.world_life_expectancy]. The fields comments, lat, and lng are empty, so they are good candidates for this operation.

  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 (main.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 comments.
  7. Click (eye) icon on the comments line.

    The icon next to the comment field changes to (slashed eye).

  8. Under Measures, find the fields lat and lng, and hide them.
  9. Click Save.

In the updated Fields interface, Dimensions table has a total of 11 fields and Measures table lists a total of 7 fields, as before.

  • The number of Dimensions is 11. This is calculated as All Dimensions (11) - Hidden Dimensions (1) + Segment (1).
  • The number of Measures is 6. This is calculated as All Measures (7) - Hidden Measures (2) + Record Count (1).

However, when using Visual Designer, the hidden fields do not show.
