Plot 2d with pyvista

[HumbertHumbert7]

Hi, is it possible to realize a classical 2d contour plot with pyvista? If it is possible how can I do? (I can add my code if needed).

Please refer code in this link.

Hi tkoyama010, thank you for your reply.

That's my plot obtained with pyvista (I can also add the code, if you need to see it). I just would like, if possible, to mantain it in this way and just add the axis and possibly a grid. Do you know how can I do it?

You can find instructions on how to add contour lines to a mesh here.

Thank you tkoyama010, however I would like to know if there is the possibility to obtain a plot like this with pyvista

So, just add the axes in this way.
(This one was done with matplotlib).

You can show the bounds axis using the show_bounds method. See show_bounds method API document for more detail.
(Edit: To make a 2D view, you can control cpos arg in the show method. See show method API document for more detail. Also, enable_parallel_projection is also useful to make it a 2D view.)

import pyvista as pv
from pyvista import examples

mesh = pv.Sphere()
plotter = pv.Plotter()
actor = plotter.add_mesh(mesh)
actor = plotter.show_bounds(
    grid='front',
    location='outer',
    all_edges=True,
)
plotter.enable_parallel_projection()
plotter.show(cpos="xy")
