[pstricks] pst-bar With Non-Numeric Data?

   Reading the pst-bar doc tells me that the external data file must have
only numeric values following the header line. This makes me ask if PSTricks
is the appropriate tool to produce a bar chart/histogram for precipitation
amounts at a station.

   The data consist of a date (from 2008-01-01 through 2010-12-31 inclusive)
and the precipitation amount (comma separated). However, there are 50 dates
for which no measurements are available. A pst-bar data file constraint is
that each row have the same number of elements. Having no measurement is
different from a recorded 0.00 and the file currently uses NA for use in R.

   Because my data violate the two pst-bar constraints (only numeric and the
same elements on each row), I'd appreciate suggestions on how to illustrate
these data effectively.
