Hello, in the help of show I read:
``figsize``- [width, height] (same for square aspect)
I'm wandering, are width and height expressed in pixels, centimeters or
what? Can I change this? (I.e. spell it in pixels or centimeters as I
need)
thanks

Hello, with plot_vector_field I can draw the vectors of a given field.
However, how can I plot field lines? I.e. the curves that have the
vectors show by plot_vector_field as tangents.
If there is not a built-in function, any idea on writing one ad-hoc?
kind regards,

Hello, I can't understand how the ticks option works in plot()... I
want to have no ticks or labels on the axis.
Also, is it possible to show the arrows on the axis? like this:

d of course just launch from a terminal and then Ctrl+C, but I'm
wondering, shouldn't there be a way to quit from the browser? My
situation is the one which anyone launching Sage from a desktop icon,
menu etc. will find himself

hello,
why is the below code plotting a flat function rather than a box one?
renato
def box(x,c):
if abs(x) < c:
return 1

var('x')
plot(box(x,1),(x,-3,3))
