           plot type

          There group is always the last available one. Subgroup is
          always the first one.

           steppar  - Plot a 2-dim parameters/chi^2 dependency of
                      last computed values  created with the command
                      "steppar". For this the first parameter of the
                      steppar command is taken.

           Apart from IDL oplot keywords following special
                      are defined:
          deviation - Flag. If true (=1) the parameter values are
                      measured in deviation from the best-fit
                      parameter value.
          nofancy   - Flag which disables plotting of significance
                      levels etc.

           Plots in current window.
