When carrying out probabilistic simulations, you may often run hundreds or thousands of realizations. In order to analyze the results, it is often quite useful to classify the realizations into categories. A category is simply defined by a condition relating one or more outputs in the model (e.g., those realizations in which the discount rate was above 3.5%; those realizations in which the profit exceeded $1,000,000; those realizations in which the peak concentration was between 1 mg/l and 10 mg/l).
Classification categories are defined at the bottom of the Monte Carlo Result Display Properties dialog:
This dialog can be accessed from the Monte Carlo tab of the Simulation Settings dialog (via the Result Options… button), and is also accessible by pressing the Options… button available in the Result Properties dialog of a Time History Result element.
When viewing a Time History result, if 1) you have run multiple realizations; 2) you have defined more than one category; and 3) you are displaying All Realizations, GoldSim will label the curves in the Time History Chart based on the categories you have defined:
In the example shown above, three categories have been defined. The chart is displaying all realizations for a single result, with each curve having a style defined by its category. (Note that for each category, you can edit the Style via the Monte Carlo Result Display Properties dialog.)
In addition, screening by category is applied when displaying time histories. That is, if you have chosen to screen out one or more categories (by clearing the Include box in the dialog above), the results (e.g., statistics, realizations) that are shown (in charts and tables) only include those realizations in the categories which you have chosen to include. In the example below, realizations falling into the Medium and High categories have been screened:
Note that the legend indicates that some categories have been screened out.
