My aim is to have a plot that has all scatter points above the diagonal a different colour than the points below the diagonal.
I came across answers for colouring partcular points in the plot that are already known. But In my case I have n number of plots that have random scatter points. The only thing common in all the n plots is the diagonal line and the x,y scale.
A = [1,3,5,7,2,5,3,7,9,5];
B = [2,6,3,5,8,6,4,2,7,3];
Diag_X = [0,10];
Diag_Y = [0,10];
scatter (A, B, '*');
plot (Diag_X, Diag_Y, 'k');
I'd like a function that could be used on any of the n scatter plots such the diagonal line is taken a reference and all the points above it are red and all below all blue.
