  The Herschel Interactive Processing Environment (HIPE) was developed by the
European Space Agency (ESA) in collaboration with NASA and the Herschel
Instrument Control Centres to provide the astronomical community a complete
environment to process and analyze the data gathered by the Herschel Space
Observatory. One of the most important components of HIPE is the plotting
system (named PlotXY) that we present here. With PlotXY it is possible to
produce easily high quality publication ready 2D plots. It provides a long list
of features, with fully configurable components, and interactive zooming. The
entire code of HIPE is written in Java and is open source released under the
GNU Lesser General Public License version 3. A new version of PlotXY is being
developed to be independent from the HIPE code base; it is available to the
software development community for the inclusion in other projects at the URL
