Errorbar limit selection
Illustration of selectively drawing lower and/or upper limit symbols on errorbars using the parameters , of errorbar.uplimslolims
Alternatively, you can use 2xN values to draw errorbars in only one direction.
Similarly and can be used on the horizontal errorbars.xuplimsxlolimsxerr
