sphere-histo is a graphical tool to depict a distribution of points in 3D space on a sphere approximated by congruent triangles. The triangles' colors indicate the density of points lying in the respective direction.

In this answer there is a solution for 2D and 3D Histograms of scattered points. The usage is simple: points, sub = hist2d_scatter( radius, density, bins=4 ) points, sub = hist3d_scatter( temperature, density, radius, bins=4 ) Where sub is a matplotlib "Subplot" instance (3D or not) and pointscontains the points used for the scatter plot.

Create rich histogram objects from numpy or dask arrays, from pandas and polars series/dataframes, from xarray datasets and a few more types of objects. Manipulate them with ease, plot them with matplotlib , vega or plotly .

Using VectoRose, it is possible to: Construct spherical histograms of directions and orientations in 3D. Construct 1D scalar histograms of vector magnitudes. Construct nested spherical …

May 25, 2023 · The code below is very much like the 3D polar plot from the Matplotlib gallery. The only difference is that you use np.meshgrid to make 2D arrays for PHI and THETA instead of R and THETA (or what the 3D polar plot example calls P).

Demo of a histogram for 2D data as a bar graph in 3D. Created using Sphinx 8.2.1. Built from v3.10.1-1-g280135670a.

Oct 23, 2024 · In this tutorial, you’ll learn how to create 3D plots using spherical coordinates in Python. Spherical coordinates provide a unique way to represent certain types of data and mathematical functions. You’ll use NumPy for data manipulation and Matplotlib for plotting. To begin, you’ll need to generate data for your spherical coordinates.

Mar 23, 2025 · In this blog post, we'll explore how to generate a 3D plot of a spherical shell using Python's Matplotlib library. Suppose you have spherical coordinate data characterized by radial distances (r_sphere), polar angles (theta), and azimuthal angles (phi).

Jan 30, 2016 · All you need is to compute a color map which is an array reprensenting the weighted density of orientation present in each subdivision of the plot and pass it as the color kwarg. (I'll look into that tomorrow but that should get …
