Graphs, Diagrams, and Tables

• Graphs, diagrams, and tables show relationships, comparisons, and changes

• Graphs should not contain much detail and should be concise

• Graphs should be used only to portray concepts.

• Different graphs serve different purposes

• A pie graph divides a whole into component parts.
• Bar graphs show relationships between two or more things.
• Line graphs show trends.
  • Remember, lines need to be bold!

• Diagrams are used to demonstrate

• Diagrams demonstrate ideas, facts, plans, concepts, processes, and sequences.
• Examples include:
  • Organizational charts
  • Flow charts
  • Gantt charts
  • Critical path networks
  • Time lines

• No more than two graphics or diagrams per slide

• More than two per slide would be WAY too much information and inundate your audience.

• When using graphs and diagrams, remember the basics

• Select appropriate type.
• Illustrate abstract concepts rather than detailed facts.
• If possible, read from left to right label directly to avoid a legend.
• Use scale values in rounded elements.
• In bar graphs place time scales on the horizontal line and other information on the left.
