; @param TAB
; The field whose we want to make a vertical cut can be 2 kind of thing:
; 1) An 2d or 3d array.
;    If the field is 2d, indicate, with the keyword BOXZOOM, geographic delineations of the boxzoom.
;    If the field is 3d, we extract the section on we average possibly before to do the plot.
; 2) a structure respecting all criterions specified by <pro>litchamp</pro>.
;    The array contained in the structure must be 2 or 3d (See case 1)
;
; @param GIVENTYPE
;
; @param GIVENMIN {required}
; valeur minimum que l'on veut prendre en compte dans le trace
; des contours. Par defaut on prend le min de tab1 (sur les pts mer)
;
; @param GIVENMAX {required}
; valeur maximum que l'on veut prendre en compte dans le trace
; des contours. Par defaut on prend le max de tab1 (sur les pts mer)
;
; @keyword BOXZOOM
; Vector indicating the geographic zone on which we want to cut the map.
;  If BOXZOOM has :
; 1 element : The extraction is made on [lon1, lon2, lat1, lat2, 0.,boxzoom[0]]
; 2 elements: The extraction is made on [lon1, lon2, lat1, lat2, boxzoom[0],boxzoom[1]]
; 4 elements: The extraction is made on [Boxzoom, 0, max([gdept, gdepw])]
; 5 elements: The extraction is made on [Boxzoom[0:3], 0, Boxzoom[4]]
; 6 elements: The extraction is made on Boxzoom
;
; Where lon1, lon2,lat1,lat2 are global variables defined at the last
; <pro>domdef</pro> !
;
; @keyword CONTINTERVALLE
; When CONTOUR is activated, it is the value between 2 isolines
; traced by a trait. So it can be different from the one specified by INTERVALLE which,
; in this case, does not control colored isolines in color anymore. If there is noone
; specified min, we choose a contour min which goes well with the specified interval!
; If this keyword is not specified, we trace 20 isolines from the min to the max.
;
; @keyword CONTLABEL {type=integer}
; When CONTOUR is activated, if n
; is different of 0, choose the label type corresponding to n cases for
; the traced by a traitisolines. To specify the type of label of the
; colored contour, use LABEL
;
; @keyword CONTMAX {default=max of the keyword CONTOUR (on ocean points)}
; When CONTOUR is activated, max value we want to consider in the isoline
; traced by a trait's line.
;
; @keyword CONTMIN {default=min of the keyword CONTOUR (on ocean points)}
; When CONTOUR is activated, min value we want to consider in the isoline
; traced by a trait's line.
;
; @keyword CONTNLEVEL {default=20}
; When  CONTOUR is activated, it is the number of contours
; traced by a trait for drawing (active if
; CONTLABEL=0).
;
; @keyword CONTOUR
; If we want to trace contours of a different field than the one
; whose we have the colored drawing (by example E-P in color and QSR in contours).
; It must be a field respecting same characteristics than the argument number one of plt.
;
; @keyword ENDPOINTS
; keyword specifying that we want to make a vertical cut in diagonal. Then coordinated of extremities
; of these ones are defined by the 4 elements of the vector ENDPOINTS: [x1,y1,x2,y2] which are
; coordinates.
;
; @keyword INTERVALLE
; Value of an interval between two isolines. If there is none specified min,
; we choose a min contour which goes well with the specified interval!. If this keyword is not
; specified, we trace 20 isoline from the min to the max. Comment: When CONTOUR is activated,
; INTERVALLE only specify the interval between 2 colored isolines. To specify the interval
; between 2 isolines traced by a trait, use CONTINTERVALLE.
;
; @keyword INV
; Invert the color vector used to color the graph
;               (without use the black, the white and the used palette)
;
; @keyword ZRATIO {default=2./3}
; When the drawing has a zoomed part, it is the size ratio between the zoomed
; part, hz (zoom height), and the whole drawing, ht (total height).
;
; @keyword LABEL {default=0}{type=integer}
; It choose the label's type corresponding to cases in <pro>label</pro>
; Comment: When CONTOUR is activated, it only specify the label's type for colored isolines.
; For these ones traced by a trait, use CONTLABEL.
;
; @keyword MASKFILL
; set to 0 to avoid to fill the masked values
;
; @keyword MAXIN
; to specify the max value we want to plot with a keyword instead of with the
; input parameter max. If max is defined by both, parameter and keyword, the
; keyword is retained.
;
; @keyword MININ
; to specify the min value we want to plot with a keyword instead of with the
; input parameter min. If min is defined by both, parameter and keyword, the
; keyword is retained.
;
; @keyword NLEVEL {default=20}
; Number of contours to draw. active if
; LABEL=0 or is not specified.
;
; @keyword NOFILL
; To make just isolines with no filling
;
; @keyword NOMASK
; activate to suppress the use of the land-sea mask when plotting the field
;
; @keyword NO_PARTIALSTEP
; activate to suppress the use of partial steps (force key_partialstep = 0 within pltz)
;
; @keyword NOTRI
; To force not to use the triangulation. Beware, in this case, the
; drawing only works if the grid is undeformed (It means that each point of a longitude
; give one latitude and each point of a latitude give one longitude) except if we use
; the keyword CELL_FILL=2.
; Comment: if the field contain points !values.f_nan, then we even do a triangulation.
;
; @keyword MASKDTA
; 2d array defining the mask that must be applied to the data instead
; of the default mask which is defined according to the grid (t/u/v/f mask)
;
; @keyword OVERPLOT
; To make a plot over an other one.
; Comment: Contrarily to the use of CONTOUR or VECTEUR, the use of this keyword
; does not the caption and/or the color bar.
;
; @keyword SIN
; Activate this keyword if we want the x axis to be traced in sinus of the
; latitude when we make a drawing f(y)
;
; @keyword STRICTFILL
; Activate this keyword to that the filling of contours be
; precisely done between the min and the max specified. Values inferior/superior at the
; specified min/max are not filled. Note that max values a considered
; as missing values so cells containing one or more corners with
; values above max will have no contours drawn through them.
;
; @keyword STYLE {default=style=0}
; Contour's style to adopt to draw isolines. See <pro>style</pro> for more informations
;
; @keyword WDEPTH
; To specify that the field is at W depth instead of T
; depth (automatically activated if vargrid eq 'W')
;
; @keyword XZ
; Force to make a cut following xz
;
; @keyword YZ
; Force to make a cut following yz
;
; @keyword ZOOM  {default=200m or max depth if it is inferior at 200m}
; Depth where i can make our maximum zoom.
