def pyclustering.cluster.optics.ordering_visualizer.show_ordering_diagram (   analyser,   amount_clusters = None  )

static

Display cluster-ordering (reachability-plot) diagram.

Parameters

[in]	analyser	(ordering_analyser): cluster-ordering analyser whose ordering diagram should be displayed.
[in]	amount_clusters	(uint): if it is not 'None' then it displays connectivity radius line that can used for allocation of specified amount of clusters and colorize diagram by corresponding cluster colors.

Example demonstrates general abilities of 'ordering_visualizer' class:

# Display cluster-ordering diagram with connectivity radius is used for allocation of three clusters.
ordering_visualizer.show_ordering_diagram(analyser, 3);

# Display cluster-ordering diagram without radius.
ordering_visualizer.show_ordering_diagram(analyser);
