Detailed Description

Class to greatly simplify the task of drawing TGraphs on a background of Antarctica This class expects you to provide lon, lat as the X, Y inputs. Get it the right way round! It then talks behind the scenes to RampdemReader and converts those numbers to Easting/Northing The Draw option has been redefined to plot everything on a background of Antarctica.

Getting something approximating standard TGraph drawing behaviour was a massive pain... There's probably a few bugs in here still, but I'm happy enough with the current functionality.

Constructor & Destructor Documentation

TGraphAntarctica::TGraphAntarctica	(	const BaseList::path &	p,
		UInt_t	interpSeconds = 0
	)

Constructor for BaseList::path

Parameters

p	is the const reference to the path
interpSeconds	is a time to interpolate between point, if 0 the raw data is used and no interpolation is done (default=0)

Member Function Documentation

void TGraphAntarctica::ExecuteEvent	(	Int_t	event,
		Int_t	x,
		Int_t	y
	)

Interactive magic.

Parameters

event	is the user interaction
x	is the x-coordinate of the pixel under the mouse
y	is the y-coordinate of the pixel under the mouse

TGraphAntarctica * TGraphAntarctica::makeGpsGraph ( int  firstRun, int  lastRun, int  gpsTreeStride = defaultGpsTreeStride, bool  quiet = true  )

static

Construct a TGraph antarctica from run firstRun to lastRun (inclusive) This is mostly for plotting purposes, otherwise

Parameters

firstRun	is the first run
lastRun	is the last run
pointEvery
quiet	default true

Returns

the newly constructed TGraphAntarctica

Definition at line 76 of file TGraphAntarctica.cxx.

void TGraphAntarctica::SetPoint ( Int_t  i, Double_t  lon, Double_t  lat  )

virtual

Set the ith point of the Graph to a longitude/latitude Handles the conversion to easting/northing internally

Parameters

i	is the graph point
lon	is the longitude
lat	is the latitude

Definition at line 43 of file TGraphAntarctica.cxx.

void TGraphAntarctica::SetPoint ( Int_t  i, const AntarcticCoord &  coord  )

virtual

Set the ith point to the position held in the AntarcticCoord

Parameters

i	is the point to set
coord	is the position (is internally converted to WGS84)

Definition at line 57 of file TGraphAntarctica.cxx.

void TGraphAntarctica::SetPointEastingNorthing ( Int_t  i, Double_t  easting, Double_t  northing  )

virtual

Don't do the conversion from lon/lat to easting/northing

Parameters

i
easting
northing
