Those syntax plot by considering one value of err. I want to plot different axes errors (error in x axis and error in y axis. If I plot with
errorbar(x,xerror,'s',y,yerror,'o') or errorbar(x,xerror,y,yerror,'o') or errorbar(x,y,xerror,yerror,'o') where xerror=sqrt(x) and yerror=sqrt(y)
nothing works at all.
