31	------------------------------------------------------------------------
32
33	This function is used by uvmat to plot fields. It automatically chooses the representation
34	appropriate to the input field structure:
35	2D vector fields are represented by arrows, 2D scalar fiedlds by grey scale images or contour plots, 1D fields are represented by usual plot with (abscissa, ordinate).
36	The input field structure is first tested by check_field_structure.m,
37	then split into blocks of related variables by find_field_indices.m.
38	The dimensionality of each block is obtained by this fuction
39	considering the presence of variables with the attribute .Role='coord_x'
40	and/or coord_y and/or coord_z (case of unstructured coordinates), or
41	dimension variables (case of matrices).
42
43	function [PlotType,PlotParamOut,haxes]= plot_field(Data,haxes,PlotParam,KeepLim,PosColorbar)
44
45	OUPUT:
46	PlotType: type of plot: 'text','line'(curve plot),'plane':2D view,'volume'
47	PlotParamOut: structure, representing the updated plotting parameters, in case of automatic scaling
48	haxes: handle of the plotting axis, when a new figure is created.
49
50	INPUT
51	Data: structure describing the field to plot
52	(optional) .ListGlobalAttribute: cell listing the names of the global attributes
53	.Att_1,Att_2... : values of the global attributes
54	(requested) .ListVarName: list of variable names to select (cell array of char strings {'VarName1', 'VarName2',...} )
55	(requested) .VarDimName: list of dimension names for each element of .ListVarName (cell array of string cells)
56	.VarAttribute: cell of attributes for each element of .ListVarName (cell array of structures of the form VarAtt.key=value)
57	(requested) .Var1, .Var2....: variables (Matlab arrays) with names listed in .ListVarName
58
59	Variable attribute .Role :
60	The only variable attribute used for plotting purpose is .Role which can take
61	the values
62	Role = 'scalar': (default) represents a scalar field
63	= 'coord_x', 'coord_y', 'coord_z': represents a separate set of
64	unstructured coordinate x, y or z
65	= 'vector': represents a vector field whose number of components
66	is given by the last dimension (called 'nb_dim')
67	= 'vector_x', 'vector_y', 'vector_z' :represents the x, y or z component of a vector
68	= 'warnflag' : provides a warning flag about the quality of data in a 'Field', default=0, no warning
69	= 'errorflag': provides an error flag marking false data,
70	default=0, no error. Different non zero values can represent different criteria of elimination.</pre></div>
