Poly Arc does a good job

It all depends on how your data should be interpolated. If you want to try and simulate a smooth trajectory then interpolating the points with a Nurbs curve (test which degree works best for you) is probably a good idea.

If you don't like the idea of the interpolation generating potentially spurious detail, then using a polyline is probably best.

Ultimately, you can even interpolate your points using the [Interpolate Data] component which allows you to switch between linear, cubic and Catmull quickly.

Incidentally, if all your points are in polar coordinates, perhaps it makes more sense to then also interpolate them in a polar system rather than interpolating them in Euclidean space.

Ah, the second group should be called "Map from polar to XYZ"....

Works beautifully. Thanks!

are you the real man behind grasshopper? did you build this up on your own? Are you THE david rutten?

Is there any document out there, where I can find each component in this way:

Vector ===> Point ===> Point XYZ

Or do I have to do this list on my own?

If there is a list flying around on the world wide web, that you know, I would be glad, if you give me it ... Thank you ...

The tabs+toolbars work in that way. You can browse through all components sequentially...

I don't think I understand the question.

For every component a sentece like: category ==> subcategory ==> component ... does a text document for this exist?

for example:

Vector ===> Point ===> Point XYZ

Run the attached file to get such a list.
