mvpa2.misc.plot.base.plot_samples_distance(dataset, sortbyattr=None)

Plot the euclidean distances between all samples of a dataset.

Parameters :

dataset : Dataset

Providing the samples.

sortbyattr : None or str

If None, the samples distances will be in the same order as their appearance in the dataset. Alternatively, the name of a samples attribute can be given, which wil then be used to sort/group the samples, e.g. to investigate the similarity samples by label or by chunks.
