  • 1. Lines © http://www.flickr.com/photos/twinysam/4988273864/
  • Never use 0pt line width Wrong Right Visible from the far end of the room
  • Have consistent line width Wrong 0.06 0.32 0.10 Right 0.06 0.06 0.32 Maybe two very different widths; not more
  • Use only one line ending Wrong Right People at the far end wont see the difference
  • Use one dashed style Wrong Right Guess
  • Arrows instead of lines vs. When? See example on next slide
  • Use connectors, not straight lines With lines With connectors
  • Shapes instead of lines (sometimes) Phase 1 Phase 2 Phase 3 vs. Phase 1 Phase 2 Phase 3 They look better on simple workflows
  • Colors instead of outlines (sometimes) vs. Useful to reduce the number of colors

  • One nesting level per slide Wrong Unique slide
  • One nesting level per slide Right Slide 1
  • One nesting level per slide Right Slide 2
  • One nesting level per slide Right Slide 3
  • One nesting level per slide Right Slide 4? Is this level really needed?
  • But, wont adding slides increase the presentation complexity?Yes, it will.But less than nested shapes.
  • Complexity → → ting Nes Sli d es → 1 slide / 1 nesting level
  • If you need everything in one place You are not making a presentation Consider other formats

  • Color count Fill + Text + Lines - Background Fill = Green + Red = 2 Hi Text = White = 1 Lines = Black = 1 Background = White = -1Bye! 2+1+1–1=3
  • Color count should be ≤ 3
  • The magic of combinatoryIm only using threestill but here colors combi-can make many nations
  • When in doubt, use Primary colors Red Yellow Green Blue #c5000b #ffd320 #008000 #0084d1 In LibreOffice: Chart 11, Chart 3, Green, Chart12 These are awesome for diagrams
