📖 Creating Groups

Group Your Data

  • Group is used only for Dimensions (X)
  • 데이터 패널(Dimensions Shelf) → 차원 우클릭 후 그룹 생성 → 클립 모양 아이콘

    1) visualization using labels (막대 하단의 라벨 클릭)
    Tableau will add a new consolidated mark

    2) visualization using marks (막대 클릭)
    Tableau will use color to distinguish the group from all oher values
    → 그룹으로 묶인 것 + Other

📖 Creating Sets

1) a dynamic set
2) a fixed set
3) Combined Set

  • Data pane - right click a dimension and select Create - Set
  • Using Label in the view
  • From Mark in the view
  • 연결된 원본 데이터를 수정하면 Set를 만들때 걸어둔 조건에도 반영됨

📖 Creating Hierarchies

  • using hierarchies for unknown geographic locations
  • It is possible to add a field to more than one hierarchy
  • to organize related fields together
  • to add drilldown functionality for fields

📖 Adding a Filter

  • viewing only certain fields in your view
  • ONLY filtering the values from the particular worksheet
  • When creating a new sheet, original data will be present by default
  • 차원, 측정값에 적용되는 필터가 다르다.
  • 날짜도 차원 또는 측정값 필터로 적용 가능
    • Relative dates
      For a relative date filter, the default anchor is Today's date
    • Range of dates
    • Starting date
    • Ending date
    • Special
  • discrete dimension → General / Wildcard / Condition / Top
  • filter options(discrete dimension)
    • Single Value (list)
    • Single Value (dropdown)
    • Single Value (slider)
    • Multiple Values (list)
    • Multiple Values (dropdown)
    • Multiple Values (custom list)
    • Wildcard Match
  • filter options(continuous measures)
    • Range of values
    • At most
    • At least

📖 Create Clusters

  • To identify marks with similar characteristics
  • Clustering helps to reduce data noise based on measure values.

📖 Create Parameters

  • Allowable values
    • All
    • List
    • Range
  • Parameter is used to replace constant value in Calculated Field, Reference line, Set, and Bins
  • We cannot use Multi-Select option in Parameter
