> I still couldn't find the equivalent of xticklabels Ok. Figured it out. The description of xlabel in jwiki is wrong - It is not "datapoint" (based on the error message, it should be "one label per tic position"). xlabel* c [#none ] x labels (one label per datapoint) It works wonderfully. Thank you very much for the package!
