Unable to format Line Chart as per the requirement

I have a requirement to format the graph visual in such a way , I need to show two different colours on a same line with respect to a condition ( The values that are in range btwn 0 to 4 need to be differentiated from rest of the range ) i can able to show the two different colors in same line with using of below measures

orange_line = SUMX(FILTER('Sheet1',Sheet1[Projected_Sales]<=3),'Sheet1'[Earnings])

Blue_line = SUMX(FILTER('Sheet1',Sheet1[Projected_Sales]>=3),Sheet1[Earnings])

but i can able to see the two earning values when i was overhere on sales 3 but i want to see the only single earnings value when i was overhere on value 3,

 

Projected_Sales	Earnings
0	0
1	425
2	850
3	1275
4	1700
5	2125
6	2550
7	2975
8	3400
9	3825
10	4250
