  • Uninformative with too much data

Scatter plot


Line graph

  • Also ubiquitous!
  • Good for showing one variable (e.g., time) as continuous even though you have discrete measures
  • Can compare several discrete groups

Line graph


Bar graph

  • aka "dynamite plot"
  • Ubiquitous!
  • Can be used for lots of discrete grouping factors
  • Natural semantics of grouping 
  • Conceals data
