Create a 2D matplotlib plot from Slices

[jacobgrasmick]

Say I create a slice via the Slicing tools:
https://docs.pyvista.org/examples/01-filter/slicing.html?highlight=slicing

I would like to be able to achieve any of the following:

1. extract a numpy array of the slice(s)
2. plot a slice in a 2D plot such as matplotlib

I can see this being a challenge if the slice is generated via slice_along_line...

There are a few examples of doing this with a planar slice: see #70 and #89

As for doing this with a curvilinear slice produced from slice_along_line that is a bit more complex but doable. I will come back to this (hopefully this evening) to post an example.

Hello.

This question is still relevant. How to get the right order of points from slice that was created by slice_along_line?

Matplotlib 2D (using points attribute from slice):

Pyvista 3D (everything looks good):

[banesullivan]

I believe the problem is that you are projecting the 3D line onto a 2D plane in your Matplotlib plot, that's why you see the line going back on itself...( from an quick glance)

Hi, @banesullivan , thanks for the reply. I got the answer in this discussion pyvista/pyvista#2798 there is a more suitable example.
