bar3(randi(6000,[4,5]).*(1:5));
colors = [0 0.2 0.7; 0.8 0 0.1; 0 0.5 0; 0.5 0 0.5; 0 0.4 0.7]/0.8;
colormap(colors)
xticklabels({'EVA1' 'EVA2' 'EVA3' 'EVA4' 'DNO'})
yticklabels([125 100 75 50])
ylabel('Battery degradation cost ($)')
zlabel('Benefit ($)')
set(gca(),'View',[-60 30])
ll = light('Position',[-1 0 0]);
