George -
You could make box and whisker charts, which don't show every point but
give an indication of the variability within the data set. I'd probably
start with a small number of charts, using ball type, drop height, and
surface as the categories in the first three charts. Then I'd get
fancier, breaking out multiple categories in the same chart. For a clue
on setting up data and axis tick labels, see these posts from yesterday:
