Hi Joe,
Curly vectors are implemented under-the-hood as an alternate form of streamlines. When a vector is long enough to pass over grid boxes neighboring its point of origin, those boxes are excluded from consideration for starting a new vector. So yes, there is some automatic thinning taking place, and there is for now no way to turn this feature off. The only possibility is to set the reference length to a short enough value that high magnitude vectors stay within a single grid box. Not a satisfactory solution I expect. We can consider adding an option to override this behavior.

In both cases I want to plot every single vector, i.e. not skipping any. The only difference in my two scripts is the definition of vcGlyphStyle, yet when I plot using curly vectors, the arrow density is significantly less than when using straight arrows. Does using curly vectors thin the array by default? Is there a way to turn this off?
