Hope I can post this question here.
So I've got some data I'm pushing into a line graph. Now I want to retrieve high 'spikes' in the graph e.g.
A - 34
B - 23
C - 96
D - 54
E - 44
The value for D is much higher than the rest, this I want to retrieve. Is there any mathematical formula to do this or could help in the development of a programming algorithm?
