  values= [lonlatbox]:[mapres]:[colorbarvals]:[xtrmbasin]:[mapdraw]:[veclength]:[plotcountry]:[basinidn]:
      [gtit]:[kindfig]:[figuren]
    [lonlatbox]= [lonSW],[lonNE],[latSW],[latNE] coordinates of the lon/lat box
    [mapres]= resolution of the mapping information to lon/lat
      * 'c': cure
      * 'l': low

      * 'h': high
      * 'f': full
    [colorbarvals] = [cbarname],[fmtcolorbar],[orientation]
      [cbarname]: colorbar name for the colors
      [fmtcolorbar]: format of the numbers in the color bar 'C'-like ('auto' for %6g)
      [orientation]: orientation of the colorbar ('vertical' (default, by 'auto', 'horizontal')
    [xtrmbasin]= [minbasin],[maxbasin] minimum and maximum basin numbers to define color range
    [mapdraw]= whether to draw the map (and project the data) or not ('True/False')
    [plotcountry]= whether country lines should be plotted or not ('True/False')
    [plotbasinid]= whether id of the basins should be plotted or not ('True/False')
    [gtit]= title of the graph ('|', for spaces)
    [kindfig]= kind of figure
    [figuren]= name of the figure
    [closefig]= whether figure should be closed or not
