The compare machenism is as following:
The value block in the figure means a position which is going to be
compared and users can use _7443_check_compare_data() to
check it. Notice that at the final compared point, it will still load a
“after-final” point into the “value” block. Please fill a dummy point into
the compare table array at the final position and this value must be
far away from table’s stroke.
If using _build_compare_function() , it will load a dummy “after-final”
point automatically. This value is (End point + Interval x Total counts )
