Detailed Description

Draw an arrow between two lon/lat points.

Handles conversion from lon/lat to Easting/Northing internally. Currently doesn't have the fancy Draw behaviour that TGraphAntarctica does. I suppose that could be added if required.

Constructor & Destructor Documentation

TArrowAntarctica::TArrowAntarctica ( )

inline

Default constructor for ROOT, pretty useless

Definition at line 25 of file TArrowAntarctica.h.

TArrowAntarctica::TArrowAntarctica ( Double_t  lon1, Double_t  lat1, Double_t  lon2, Double_t  lat2, Float_t  arrowSize = 0.01, Option_t *  option = "|>"  )

inline

Slightly useful constructor

Parameters

lon1	is the longitude of the first point
lat1	is the latitude of the first point
lon2	is the longitude of the second point
lat2	is the latitude of the second point
arrowSize	is the size of the arrow (default = 0.01)
option	arrow draw option (default is "|>", which is a solid arrow head pointing towards the second point)

Definition at line 37 of file TArrowAntarctica.h.

TArrowAntarctica::TArrowAntarctica	(	TGraphAntarctica *	gr1,
		TGraphAntarctica *	gr2,
		Int_t	i1 = 0,
		Int_t	i2 = 0,
		Float_t	arrowSize = 0.01,
		Option_t *	option = "|>"
	)

Perhaps an even more useful constructor. Draws an arrow between two points of two TGraphAntarcticas (or the same one, if you pass it twice)

Parameters

gr1	is the first TGraphAntarctica, defines the first point
gr2	is the second TGraphAntarctica, defines the second point
i1	is the point of the first TGraphAntarctica to use as the first point (default =0)
i2	is the point of the second TGraphAntarctica to use as the second point (default =0)
arrowSize	is the size of the arrow (default = 0.01)
option	arrow draw option (default is "|>", which is a solid arrow head pointing towards the second point)
