I think that's a serious problem. This is now trac #3350. Seems like
the problem must be close to the call on "setup_for_eval_on_grid" in
sage/plot/plot.py but I haven't totally tracked it down yet.

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/ca
You can use the plot_vector_field command:
# Declare your variables:
var('x t')
# Define you function, for instance:
def f(t,x):
return t*x
# Plot the associated vector field:
plot_vector_field((lambda t, x: 1, f(t,x)), (-1, 1), (-2, 2))
There seems to be something awry, however, compare
