Should have noted that the data (atmospheric emissions) in * the second dataset is heavily positively-skewed. (This leads to a problem with the legend when plotting deciles--all but one or two of the decile labels overprint near the bottom of the scale--but will post separately about that.) * the first dataset is much more evenly distributed over its range. (This is due to a bug in its logging, hence the need to correct it.) >> First plots to PDF as expected (title, data, legend).

Thanks, but :-) given the non-list call works on the more- evenly-distributed source data, but fails on the skewed target data, there would seem to be a bug, if only in the doc. (If you've got a bugzilla or similar, please let me know, and I will make an entry.) Your assistance is appreciated!
