Parameters
data
in
required
The field we want to display can be:
1) an array. If the array is not a 2D array, its mean along
the z and t direction will be automatically performed
(as it is done in plt).
2) a structure respecting all criterions specified by
litchamp
min
in
optional
default: min of DATA (on non-masked points)
max
in
optional
default: max of DATA (on non-masked points)
Keywords
BOTTOM
default: 1
The lowest color index of the colors to be used.
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
domdef !
C_MASK
default: 0
The color number that should be used for the mask values.
C_NAN
default: !d.n_colors < 255
The color number that should be used for the NaN values.
INV
Reverse the color order
MININ
MAXIN
MASKVAL
default: 1.e+20
The mask value. Note that if abs(mask) < 1.e6, then the
exact value of the mask is used to find the maskwd point.
if abs(mask) > 1.e6, the test to find the masked value is ge
abs(mask)/10. This is necessary to avoid the rounding errors
NCOLORS
default: (d.n_colors < 256) - 1 - BOTTOM
number of colors to be used.
NOINTERP
Used this keyword if you don't want that the values
are interpolated from BOTTOM using NCOLORS colors.
This can be for example useful when working on byte type arrays.
_EXTRA
Used to pass keywords to placedessin, TV,
axe, legende, barrecouleur,
terminedessin
