Inclusion of a 3d lines functionality ?

[thejasvibr]

The Scatter3d function allows users to plot separate points in 3d space. - which is useful for many kinds of data visualisation. However, in the case of trajectory visualisation or to visualise overlayed data - it would be useful to be connect these points with lines.

In addition to Scatter3d would it be possible to include something like a 'Line3d' option in the Holoviews library ?

This should be a fairly straightforward addition and seems worthwhile.

[jlstevens]

What would it be called Path3D seems like the most consistent match?

[philippjfr]

I think I'd prefer Line3d or Curve3d, Path has specific connotations in HoloViews which differs from a simple line.

Seems like this is the 3D extension of hv.Curve, so it should be hv.Curve3d, right?

[philippjfr]

Agreed, I'm wondering whether we should slowly migrate to Curve -> Line, in which case Line3D would be more consistent and future compatible.

[jbednar]

Ah. Coincidentally, Gus just brought that up again, and we do need a way for people to find "Line" plots, so maybe indeed Line3d.

All of this brings up the question of interpolation between Points.
In 2D, hv.Curve has a (limited) number of interpolation options.
In 3D, the options are even more interesting...

[jlstevens]

Honestly, I don't mind the name Line or Line3D. The problem is maintaining backwards compatibility nicely and I don't really want to documented different 'elements' that are essentially aliases of each other.

[philippjfr]

Matplotlib and plotly implementations of a 3D line were added in 1.11.

[jbednar]

To clarify, this was added as Path3D.
