PDP Chart / 2D

The PDP Chart shows a partial dependence plot: the marginal effect of one parameter (PDP Chart) or two parameters (PDP Chart 2D) on the objective predicted by a surrogate model, with the remaining parameters averaged out. It answers "how does the objective change as this parameter varies, in general?"

Because it is model-based and marginal, it differs from the Response Surface 3D widget, which shows a conditional slice through one anchor design instead of averaging.
