Questions and Answers

What is the primary consideration for determining if a column should be used for slicing and dicing in time series charts?

  • How Superset should parse the datetime format
  • Whether the column is filterable
  • Whether the column is temporal (correct)
  • Whether the column is dimensional

    • Why is it important to consider if a column is filterable when customizing column properties?

  • To ensure the column can be used for slicing & dicing in charts (correct)
  • To determine if the column is temporal
  • To decide how Superset should parse the datetime format
  • To ascertain if the column is dimensional

    • When customizing column properties, what determines how Superset should parse the ISO 8601 datetime format?

  • The column's datatype (correct)
  • The dimensionality of the column
  • The filterability of the column
  • The temporal nature of the column
