Conditional Format segments of Line Chart

[Excelam]

Hello All,

I'm looking for a way to conditional format each segment of a line chart. Basically, if the segment is positive (from a lower point to a higher point) I want to the segment to be green. If the segment is negative ( higher point to a lower point) I want to the segment to be red. Any thoughts. All help is sincerely appreciated!
