So I would like to add std bars to each individual value on this graph I made and am unsure how to do it. Here is the code I used to produce the graph. The Standard Deviation is different for each value as well. I apologize if the code is poor or if it is confusing. The chc and cnhc does have meaning to me but probably not to anyone else so I apologize if that is confusing.

chc6 = [3875.1 3875.1 3874.9 0 0 0 0 0 0 0 0];
chc8 = [0 0 0 3875.4 3874.9 3871.5 3871.7 3874.5 3874.9 3876.9 3879.6];
nchc2 = [3882.8 0 0 0 0 0 0 0 0 0 0];
nchc4 = [0 3891.2 3886.5 0 0 0 0 0 0 0 0];
nchc8 = [0 0 0 3895.5 0 0 0 0 0 0 0];
nchc10 = [0 0 0 0 3900.6 3900.4 0 0 0 0 0];
figure(1), plot(chc6, 'ko')
figure(1), hold on, plot(chc8, 'go')
figure(1), hold on, plot(nchc2, 'rd')
figure(1), hold on, plot(nchc4, 'bd')
figure(1), hold on, plot(nchc8, 'gd')
figure(1), hold on, plot(nchc10, 'md')

That doesn't allow me to have different error bars for each value tho. Unless I am missing something

Errorbar is super flexible (see the examples " Control Error Bars Lengths in All Directions" or " Plot Vertical Error Bars that Vary in Length") in the doc. Overlapping points or bars can be solved by adding a small value to x.
