# Documentation

import the grace class
>>> from pygrace import grace

instantiate the grace class
>>> pg = grace()

get help
>>> pg.doc()
prompt() --> start interactive session
eval(command) --> execute a grace command
put(name,val) --> put variable into interactive session
get(name) --> get variable from interactive session
who([name]) --> return the existing grace variables
delete(name) --> destroy selected pylab variables
restart() --> restart a grace window
grace and Numpy must be installed, grace also relies on (open)motif

"pygrace: python bindings to the Grace plotting package", Michael McKerns,

use grace methods directly from the python interpreter
>>> from Numpy import *
>>> x = []
>>> for i in range(21): x.append(i*pi/10)
>>> pg.plot(x,sin(x))

push python variables into grace and interact with grace scripting language
>>> pg.put('x',x)
>>> pg.put('y',cos(x))
>>> pg.eval('s0 line color 2')
>>> pg.eval('plot(x,y)')

use the interactive grace prompt
>>> pg.prompt()
grace interface:
grace> histoPlot(y)
grace> s0 fill color 3
grace> redraw()
grace> exit

check variables in grace session
>>> pg.who().keys()
['y', 'x']
>>> pg.who('x')

get variables back into python from grace
>>> cosx = pg.get('y')

use shortcuts for put, eval, and get
>>> pg.z = 0.5
>>> pg('print z')
>>> pg.z + 1

delete variables from grace
>>> pg.delete('x')
>>> pg.delete('y')
