"The logarithmic scaling does not work if the problemScale is ambiguous and therefore set to -1L in ProblemBenchmarkResult.class.
While creating a chart having problems with ambiguous scale JfreeChart is throwing a Runtime Exception:"

Solution proposals:
Proposal A) don't add a point on the graph for a result with a problem scale of -1. Problem X: Given result A, B, C: if A and C have a problem scale, and B has -1, then the color of C will be different in graphs with the problem scale and graphs without it. That's not acceptable, because it is extremely misleading. Make sure to manually test problem X by configuring a benchmark to reproduce that case!
Proposal B) Like proposal A, but still add with a problem scale of 0.
Any other proposals we can think of?
