These two arguments can be given to select a fit range.
//  Fit range
//  =========
//  The fit range can be specified in two ways:
//    - specify rxmax > rxmin (default is rxmin=rxmax=0)
//    - specify the option "R". In this case, the function will be taken
//      instead of the full graph range.
