About UMatrix visualization (question)

[rosaguilar]

I am modelling a time series with a certain number of points (rows). I want to plot the UMatrix but filter the labels to specify only those belonging to a certain year. I know how many rows are per year. So, does passing a range to the _view_matrix make sense?
My code only has a little modification as follows:
if labels is not None:
for label, col, row in zip(_filter_array_local(som, labels, zoom),bmu_coords[:, 0], bmu_coords[:, 1]):
line 456--> if label is not None and label in label_range:
axes[i].annotate(label, xy=(col, row), xytext=(10, -5),
textcoords='offset points', ha='left', va='bottom',
bbox=dict(boxstyle='round,pad=0.3', fc='white', alpha=0.8))

Where label_range is the range of rows I want to plot.
Does it make sense? I am generating several plots, and effectively, low numbers are displayed corresponding to the first years (the numpy array is ordered per years).
