Expensive graph

For a report on a model I produced some summary graphs that turned out to be rather time-consuming to generate.

Each point represents the solution of a different MIP model. In total we have 9 series × 21 points = 189 models. Each model takes between 10 seconds and 500 seconds to solve, on average about 200 seconds. So this single chart took 10 hours to generate. And there were a few others like this.
