Support plotting objects orbiting around different attractors

[anhiga]

When there are two (or more) different attractors in a plot, all of them are located in (0, 0), what leads to:

Can you upload a minimal version of the code as well?

I'm sorry, here it is 😄 :

from poliastro.neos import neows
from poliastro.plotting import OrbitPlotter

# Attractor: Earth
from poliastro.examples import iss

#Attractor: Sun
eros = neows.orbit_from_name('eros')

frame = OrbitPlotter()
frame.plot(iss, label='iss')
frame.plot(eros, label='eros')

[anhiga]

Well, actually the first plot is previous to #199 fix. Currently the problem is still the same, altough:

[astrojuanlu]

The first plot sets the frame and the attractor. We are projecting the following orbits to the correct frame, but not centering them in the correct attractor. With better reference frame handling (#218) and better hyperbolic handling (#111, itself blocked on the former) this should be possible.

Won't arrive in time for November, postponing.

[astrojuanlu]

In #332 we added a NotImplementedError, so at least now the result is not garbage. We still have to address #111 before working on this one.

Is there any reason this should be blocked now?

[astrojuanlu]

Thanks @shreyasbapat, this is not blocked anymore.

Modern way to reproduce this:

from poliastro.twobody import Orbit
from poliastro.plotting.static import StaticOrbitPlotter

# Attractor: Earth
from poliastro.examples import iss

# Attractor: Sun
eros = Orbit.from_sbdb("eros")

frame = StaticOrbitPlotter()
frame.plot(iss, label="iss")
frame.plot(eros, label="eros")
