The standard graphing library used in astronomy is PGPLOT. It is available free only for non-commercial use (see copyright.readme in the distribution tar ball). Thus, I cannot distribute a program that uses code derived from both PGPLOT and from GPL sources, because allowing commercial use would violate the PGPLOT license and forbidding commercial use would violate the GPL.
