[dxs]: style of x-axis ('auto' for 'pretty')
'Nfix', values computed at even 'Ndx'
'Vfix', values computed at even 'Ndx' increments
'pretty', values computed following aprox. 'Ndx' at 'pretty' intervals (2.,2.5,4,5,10)

[mapvalues]: drawing coastaline ([proj],[res]) or None
[proj]: projection
* 'cyl', cilindric

* 'f', full
[kindfigure]: kind of figure
'legend': only points in the map with the legend with the names
'labelled',[txtsize],[txtcol],[txtbckgcol]: points with the names and size, color of text and background
color ('None' for without)
[pointcolor]: color for the points ('auto' for "red")
[pointlabels]: ',' of labels [only used if [collab]='None'] ('None' for no labels, '!' for spaces)
[legvals]=[locleg]|[fontsize]:
[locleg]: location of the legend (0, autmoatic)
1: 'upper right', 2: 'upper left', 3: 'lower left', 4: 'lower right',

9: 'upper center', 10: 'center'
[fontsize]: font size for the legend (auto for 12)
[figureko]: kind of the output file (pdf, png, ...)
[figuren]: name of the figure
[close]: Whether figure should be finished or not
[filen]= [ncfile],[lonvarn],[latvarn][,[varn],[dimvals],[vargn],[min],[max],[colbarn],[fmtcolorbar],[orientation],[varu]]

Optional values:
[varn]: optional variable to add staff into the graph
[dimval]: '@' list of [dimn]|[dimval] to get the values for [varn]
[dimn]: name of the dimension
[dimval]: value of the dimension variable a given value is required:
* [integer]: which value of the dimension
* -1: all along the dimension
* -9: last value of the dimension
* [beg];[end];[inc] slice from [beg] to [end] every [inc]
* NOTE, no dim name all the dimension size
[vargn]: name of the variable in the graph
[min]: minimum value for the extra variable
[max]: maximum value for the extra variable
[colbarn]: name of the color bar
[fmtcolorbar]: format of the numbers in the color bar 'C'-like ('auto' for %6g)
[orientation]: orientation of the colorbar ('vertical' (default, by 'auto'), 'horizontal')
