Instead of `plot_vector_field3d`

, use the method `plot`

of vector fields:

```
vf.plot(chart=c_cart, chart_domain=c_spher, ranges={r: (2, 10)}, scale=0.2, width=2)
```

The output is

See the documentation of VectorField.plot() for explanations and more examples.

See the documentation of VectorField.plot() for explanations and more examples.

*Side note:* there are some typos in your example (`E.vectorfield`

--> `E.vector_field`

, `cart`

--> `chart`

); it should read

```
vf = E.vector_field((r,0,0), frame=f_spher, chart=c_spher, name="vf")
```

Besides, instead of `f_spher = E.frames()[2]`

, you can use `f_spher = E.spherical_frame()`

.
