  • the proportion of concerts that each dress was used for.
  • the dresses in the European leg were new.

Analysing a Plot

  • What data has gone into the plot?
  • What information do we want to get out?
  • What are the data symbols?
  • How are the data values encoded as data symbols?
  • How well can we decode information from the data symbols?

Data symbols

  • I can count seven different data symbols
    • Bars
    • Dress icons
    • Text labels
    • Data points
    • Solid lines
    • Dotted lines
    • Grey rectangles

Encodings

  • I can count twenty-two different encodings

  • Dress name is encoded as …

    • text and y-position of labels
    • colour and y-position of bars
    • colour and y-position of dress icons
    • colour and y-position of data points

Problem Encodings

  • x-position encodes frequency and time
  • frequency encoded as bar length and dress icon x-position and text label x-position
  • lack of concerts is encoded as grey rectangle
  • colour encodes dress name and album name
  • abbreviated album names encoded as text label

Encoding Importance

  • Which elements of the plot are largest/brightest?
  • Are they the most important elements?
