Besides Georg's suggestion there is a file in SAGEHOME/examples/calculus called field_plot2d.sage which does some very crude DF plotting of 1st order ODEs. (Designed specifically for teaching purposes.) You need to read it into SAGE using the attach command, edg
sage: attach "SAGEHOME/examples/calculus/field_plot2d.sage" The docstring of the file has examples.
