Has anyone found a good way to represent two pieces of data that may be skewed? For instance, when building a bar chart to show sales of a production against the budget of a production. The issue lies in the budget and sale amounts of productions. One budget may be 6 million, and another 200,000. To put them on the same chart ion a realistic scale doesn't work out so well.
Drawing on Tom's second to last paragraph, I would create a stacked bar using % based reporting = budget/revenue. This would normalize the comparisons and provide an easy graph explanation and a simplified foot note citing the total budget for each production.
