2. Introduction Graphics can be confusing Sometimes less is more Focus on the point being made Best graphics are self-explanatory Break up complicated data to make it easier to digest

3. Jumbled Mess

4. Less can be more Most important data? Remove extraneous data Don’t be afraid of multiple graphs

6. ~3100W ~2000W ~1000W ~500W

7. Observations at ~3100 W Vigorous boiling in reboiler and all trays Rapid condensation Leaking water and steam around seal

8. Observations at ~2000 W Steady boiling in reboiler and all trays Moderate condensation Seal only leaking small amount of steam

9. Observations at ~1000 W Gentle boiling in reboiler and most trays Boiling appeared to have stopped in tray 1 Very little activity in the condenser Seal stopped leaking

10. Observations at ~500W No boiling in any of the trays Slight boiling in reboiler Residual heat? No activity in the condenser

12. ~500W ~1000W ~2000W ~3100W Tray 1 Reboiler

13. Close but not quite

15. ~3100W ~2000W ~1000W ~500W Cooling Water Supply Cooling Water Return ΔT = 6.7 ΔT = 3.7 ΔT = 0.6

16. Summary Graphics can confuse audience Done properly, graphics convey a lot of information Useful for illustrating your words Big point sizes and high contrast
