I have done this. The default value is to print the descriptives because
that is the pareto.chart default result and also it good for someone to see
the values because they are not displayed at the plot.

Yes that remain from the plot I hacked. Also changed it to the barplot
plugin.

3) It would be nice to supply some options from the plot_options plugin (do

 I have done this, however there are not many options.

3b) For the problem with main, I've added some more defaults to

I can not make this work. I still get "Pareto chart for rk.temp.x." Can you
take a look at this please?
