map a hexagonal grid in matplotlib

Question

I\'m wanting to draw a figure with a hexagonal grid. The end result should look like a honeycomb. However, I\'m having trouble getting my hexagons sized correctly using matp

Answer 1

Whoever struggles with the same issue in 2020+, check out my hexalattice module: It allows to create hexagonal grids (hexagonal lattices) in 2D with fine control over spatial distribution of the hexagons, circular clop of the lattice and rotations around the central slot.

Usage and graphical output:

from hexalattice.hexalattice import *
hex_centers, _ = create_hex_grid(nx=10,
                                 ny=10,
                                 do_plot=True)
plt.show()    # import matplotlib.pyplot as plt

Installation:

'>> pip install hexalattice'

Advanced features

The module allows stacking of few grids, arbitrary grid rotation around its center, advanced control over gaps between the hexagons etc.

Example:

hex_grid1, h_ax = create_hex_grid(nx=50,
                              ny=50,
                              rotate_deg=0,
                              min_diam=1,
                              crop_circ=20,
                              do_plot=True)
create_hex_grid(nx=50,
                ny=50,
                min_diam=1,
                rotate_deg=5,
                crop_circ=20,
                do_plot=True,
                h_ax=h_ax)
