Creates and draws a streamline plot.
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl" function gsn_streamline ( wks  : graphic, u [*][*] : numeric, v [*][*] : numeric, res  : logical ) return_val  : graphic
The u and v data for the streamline plot; must be two-dimensional.res
A variable containing an optional list of plot resources, attached as attributes. Set to True if you want the attached attributes to be applied, and False if you either don't have any resources to set, or you don't want the resources applied.
A scalar id of the streamline plot created is returned. The id of the data object is also returned as an attribute called data. This is useful if you want to use setvalues to change some data options after this function has been called.
This function creates and draws a streamline plot on the given workstation.
If either u or v have a _FillValue attribute, these values will be used as missing values.
You should use gsn_csm_streamline if you want a more customized streamline plot and/or if your data has coordinate arrays.
To maximize the area that the plot is drawn in, set the special resource gsnMaximize to True.
In NCL V6.1.0, this function was updated to automatically create a labelbar if stMonoLineColor is set to False.
