say, F1(X)=\int_0^X Y^2 dY,

it does plot (you can see some dots being plotted), but without a connecting line, and in Num view, all X values get evaluated correctly.

When I enter the expression manually as you suggested, I do see points plotted. However, when I assign the function indirectly via an assignment (as previously described), I see no points (initially). Eventually, the plot does appear. This is because it takes "Forever and a day" (~1.5-2 min) for the calculator to do all the requisite integral evaluations. Needless to say, one can forget about scrolling around in the plot given this lag.
It seems the adaptive plotting routines could use some refinement- as the manually entered plot does not show enough detail (unconnected points) and the one entered programmatically generates too much (perhaps) detail in generating the plot.
