Thanks Linda, I am not sure that is exactly what I am looking for, but thank you anyway. I am interested in showing the error estimates on a line graph, e.g. see the second answer here: https://stackoverflow.com/questions/12957582/matplotlib-plot-yerr-xerr-as-shaded-region-rather-than-error-bars
It seems, J plot does not have this feature.
