### how to plot solution of differential system

Hi, everyone!
I got a question.
I have a system of three Newton's ~~equations
x''=-x/(x~~*x+y*y+z*z)^3/2-F(t)
y''=-x/(x*x+y*y+z*z)^3/2
z''=-x/(x*x+y*y+z*z)^3/2equations

```
x''=-x/(x*x+y*y+z*z)^3/2-F(t)
y''=-x/(x*x+y*y+z*z)^3/2
z''=-x/(x*x+y*y+z*z)^3/2
```

I use ~~odesolve() ~~`odesolve()`

to solve numerically the system by using ~~y[0] ~~`y[0]`

for x, ~~y[1] ~~`y[1]`

for y, ~~y[2] ~~`y[2]`

for z like in example in the manual without using ~~jacobian:
~~jacobian:

`j_1= lambda t,y: [ y[3], y[4], y[5], `~~-y[0]/(y[0]~~*y[0]+y[1]*y[1]+y[2]*y[2])^(1.5)-F*cos(w*t), -y[1]/(y[0]*y[0]+y[1]*y[1]+y[2]*y[2])^(1.5), -y[2]/(y[0]*y[0]+y[1]*y[1]+y[2]*y[2])^(1.5)]-y[0]/(y[0]*y[0]+y[1]*y[1]+y[2]*y[2])^(1.5)-F*cos(w*t), -y[1]/(y[0]*y[0]+y[1]*y[1]+y[2]*y[2])^(1.5), -y[2]/(y[0]*y[0]+y[1]*y[1]+y[2]*y[2])^(1.5)]

How may I plot the curve (x(t), y(t)) or (x(t), z(t))?

`T.plot_solution(i=0, `~~filename=outfile) ~~filename=outfile)

allows to plot only (x(t), t), (y(t), t) or (z(t), t)
Thank you
