I want to plo the data with different errorbar. I have plot the data using following code but my all errorbars of same lenght. I want erroerbars with the different lenght and auto generted. what do I need to change in my code? I am plotting the standard error .
thanks in advance!
pulsewidth_5v = 1×10
20.0000 10.0000 4.0000 2.0000 1.0000 0.4167 0.2000 0.0952 0.0645 0.0323
diameter_5v = 1×10
0.3122 0.2924 0.2624 0.2475 0.2057 0.1977 0.1797 0.1723 0.1673 0.1400
% 5v data
N = length(diameter_5v);
err = std(diameter_5v)/sqrt(N)*ones(size(diameter_5v));
errorbar(pulsewidth_5v,diameter_5v,err,"mo");

This section of the documentation explains how to control error bar length in all directions.

Just because something is a common data analysis technique, does not make it right for your data. I strongly suspect it is not.
Can you explain your data a little bit more? For example is pulsewidth_5v an independent variable that you have control over, and diameter_5v is something you are measuring? In that case, perhaps you are looking for a model to fit a function to that relationship?
In that case your "error" would be the residual between the predicted diameter and the measure diameter.
