I have a list of integers between 0 and 100 - to signify percentages. I calculate another list that is the items in the first list subtracted from 100. I feed these to a callback so I can see the pie chart change.
The pie chart is to show positive reactions versus negative reactions by a group of survey takers
pie_positive = line3_coords[n]
pie_negative = 100 - (line3_coords[n])
line3_coords [80, 80, 80, 81, 81, 82, 82, 82, 83, 83, 84, 84, 85, 85, 85, 86, 86, 87, 87, 88, 88, 88, 89, 89, 90, 90, 90, 91, 91, 92, 92, 93, 93, 93, 94, 94, 95, 95, 96, 96, 96, 97, 97, 98, 98, 99, 96, 94, 92, 90, 88, 85, 83, 81, 79, 77, 74, 72, 70, 68, 66, 63, 61, 59, 57, 55, 52, 50, 48, 46, 44, 41, 39, 37, 35, 33, 30, 28, 26, 24, 22, 19, 17, 15, 13, 11, 8, 6, 4, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 18, 18, 18, 18, 18, 18, 18, 18, 18, 19, 19, 19, 19, 19, 19, 19, 19, 19, 19, 20]
When pie_positive is greater or they are equal - works fine the positive slice follows line3_coords[n] values but …
when pie_negative is greater the the positive slice follows (100 - line3_coords[n]) values …??

Here is the output from the print statements when it starts to go wrong…
