Show persistence as a barcode
-----------------------------
This function can display the persistence result as a barcode:
.. testcode::
import gudhi
periodic_cc = gudhi.PeriodicCubicalComplex(perseus_file=gudhi.__root_source_dir__ + \
'/data/bitmap/3d_torus.txt')
diag = periodic_cc.persistence()
plt = gudhi.plot_persistence_barcode(diag)
plt.show()
.. plot::
import gudhi
periodic_cc = gudhi.PeriodicCubicalComplex(perseus_file=gudhi.__root_source_dir__ + \
'/data/bitmap/3d_torus.txt')
diag = periodic_cc.persistence()
print("diag = ", diag)
plt = gudhi.plot_persistence_barcode(diag)
plt.show()
Show persistence as a diagram
-----------------------------
This function can display the persistence result as a diagram:
.. testcode::
import gudhi
point_cloud = gudhi.read_off(off_file=gudhi.__root_source_dir__ + '/data/points/tore3D_1307.off')
rips_complex = gudhi.RipsComplex(points=point_cloud, max_edge_length=0.3)
simplex_tree = rips_complex.create_simplex_tree(max_dimension=3)
diag = simplex_tree.persistence()
plt = gudhi.plot_persistence_diagram(diag)
plt.show()
.. plot::
import gudhi
point_cloud = gudhi.read_off(off_file=gudhi.__root_source_dir__ + '/data/points/tore3D_1307.off')
rips_complex = gudhi.RipsComplex(points=point_cloud, max_edge_length=0.3)
simplex_tree = rips_complex.create_simplex_tree(max_dimension=3)
diag = simplex_tree.persistence()
plt = gudhi.plot_persistence_diagram(diag)
plt.show()
