must be missing something as you have it right there
plot("your other column",i./max(i),'.')
then you'd fit a line and error bars? not sure how or what data you'll be using to calc the error bars and the smooth curve

that's not what i'am looking for, i want to plot the current vs voltage and the result should be a sigmoid function,that sigmoid function what i'm looking for.did you saw the capture that I joined?
