Analyzing data_2

📖 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
