Not all modules are the same; stats and sfunctions are tools (there are
also other kinds, file, graph or layer module functions). You cannot
‘call’ them as data processing functions. In fact, it would be probably
quite difficult to use tools from a script as they are inherently
interactive and their interface is immensely idiosyncratic.

The following should work as a standalone script (only with stadnalone
gwy available in nightly snapshots at this moment). Removing the last
two lines should make it suitable for the console. Anyway, hopefully it
demonstrates how to create a graph window with data from a DataLine.
import gwy, gtk
c = ... load or get the container ...
f = c.get_object_by_name('/0/data') # or some other data...
l = gwy.DataLine(1, 1.0, True)
f.dh(l, 0)
gm = gwy.GraphModel()
gcm = gwy.GraphCurveModel()
gcm.set_data_from_dataline(l, 0, 0)
gm.add_curve(gcm)
g = gwy.Graph(gm)
w = gtk.Window()
w.add(g)
w.show_all()
w.connect('destroy', gtk.main_quit)
gtk.main()
