Visualization

[lbugnon]

When running

som = SOMFactory.build(traindata, mapsize, lattice='rect', normalization=None) som.train(n_job=1,verbose=0) from sompy.visualization.mapview import View2D view2D = View2D(10,10,'title') view2D.show(som)

I get error:

File "main.py", line 60, in view2D.show(som) File "/usr/local/lib/python3.5/dist-packages/SOMPY-1.0-py3.5.egg/sompy/visualization/mapview.py", line 62, in show File "/usr/local/lib/python3.5/dist-packages/SOMPY-1.0-py3.5.egg/sompy/visualization/mapview.py", line 10, in _calculate_figure_params AttributeError: 'NoneType' object has no attribute 'denormalize_by'

Any thoughts?

Also, if using normalization='var' instead of 'None', I had to add a plt.show() inside view.show(), otherwise figure is not displayed
