Partial dependence plot (PDP)

The average model prediction as one feature is set to each value on a grid, with all other features left at their observed values.

In detail

PDP(v) = mean over rows of f(v, other features of the row). Opposing effects in different segments average to a flat line, and for correlated features it evaluates combinations that never occur. Draw ICE curves beside it.
