Currently, plot names are given according to a basi numbering scheme (Pi, with i incremented automatically). This makes it difficult to correlate plot names with their contents.
It would be much better to give plots the name of the curve they contain, either when they are created or each time a curve is added/removed/renamed (though the latter may be more difficult to handle) unless the name has been changed manually.

Even special cases would be fairly easy to handle:
- plots with more than one curve: concatenate names (up to some limit, after which some sort of ellipsis sounds appropriate)
- already existing name: append something (like for vectors, which by the way should start from "-2" and not "-1")
