We memoize the checksum of the x first models, and we check that one of these models is still present when the graph view appears. If so, we do not reload the range, other wise we reload it. Scenario: f(t) = [t^2 t+1] in parametric Display the graph f(x) = 1 on ]-inf;0] g(x) = 2 on [0;inf[ Display the graph -> the range did not change
