I have bee trying to plot two data set according to their efficiency. If efficiency is greater than .8 the set should be plotted in red or if it less that .8 the data set should be plotted in blue. I am having trouble related the effeminacy with the appropriate data set to plot it. how would i do this, with out hard coding the date set. Efficiency is 'n'
D=[1 2 3 4;2 5 7 5;2 6 7 9;2 4 8 4];
n1= (D(2,:)/D(1,:));
n2 = D(4,:)/D(3,:);
V =[n1 n2];
%plot
figure('color','white');
axis([0 12 0 10]);
xlabel('Energy Input (E1) [MJ]');
ylabel('Kinectic Energy (E0) [MJ]');
title('Efficiency Analysis of Spacecraft Engines','FontSize',20);
grid
for x = min(V):max(V)
if x> 0.80
hold on
elseif x< 0.8
hold on
end
end

No plot calls there. You do not have any line() or plot() or surf() or surface() or patch() or hist() or anything else that actually plots.
