function plotVolumes(OPT,volumes)
%PLOTVOLUMES  Plot the given volume series
%
%   The call was done because OPT.plotname was given. Now the available
%   series are plotted. If volumes is empty nothing is plotted. The legend
%   is predefined for a specific volume type.
%
%   Syntax:
%   plotVolumes(OPT,volumes)
%
%   Input:
%   OPT       = options used to inform what plotting is asked for
%   volumes   = possible series  to be plotted
%
%   Output:
%   varargout =
%
%   Example
%   plotVolumes
