Try using the correct values for the FrameTicks option: instead of
FrameTicks -> {True, True, False, False}, use FrameTicks ->
{Transpose[{Range[1, 25], ToString /@ midpoints}], Automatic, None, None}.
Incidentally, to use BinCounts you need the AddOn
Statistics`DataManipulation` , instead of Statistics`DescriptiveStatistics`.
