        Description

        This procedure is used as a post-processor of the results of
        DARCYTRA or PASAPAS.

        Contents :
        ----------

        TAB2 is a TABLE result of  DARCYTRA or PASAPAS.

        MOT1 is the index name of the function to be studied
             in TAB2. TAB2.MOT1 must be a CHPOINT.

        MOT2 is a word that replaces MOT1 in the captions of the curves.

        LENTI1  list of  indexes of TAB2.'TEMPS' which are considered

        LREEL1 list of values of TAB2.'TEMPS' which are considered.
              If LENTI1 or LREEL1 are not specified we take into
              account all the times of TAB2.'TEMPS'.

        LMOTS1 list of the names of the components of TAB2.MOT1 to be
              taken into account. ( Default all )

        TAB3 is a TABLE indexed by numbers. Each index contains
             a word associated with the name with the same rank in
             LMOTS1 (Default names of components). Its index 
             'SOUS_TYPE' (optional 'SOUSTYPE' index) contains 
             'NOM_COMPOSANTE'.

        TAB4 is a TABLE indexed by numbers. Each index contains
             a word associated with the point of the same rank in
             GEO1.(Default number of the point). Its index 
             'SOUS_TYPE' (compulsory if TAB3 is not given) contains 
             'NOM_POINT'.   

        GEO1 mesh. The procedure generates an evolution for each point
             of this mesh.

        TAB1 table indexed by integers. TAB1.i is a table indexed by
             three indexes 'VALEUR' 'LEGEND1' et 'LEGEND2'.
             TAB1.i.VALEUR contains an evolution, function of
               time, for a component at one point.
             TAB1.i.LEGEND1 contains the name of this function MOT2.
               (Default MOT1).
             TAB1.i.LEGEND2 contains a string composed of the name
               associated with the component TAB3.i (Default
               LMOTS1(i)) and the name of the point TAB4.i (Default :
               word 'PT ' followed by the number of the point in GEO1),
