We need to pass the role of the data sequence in order to avoid unreliable guess work when importing static value array. Also, not all Excel's scatter plots have real numeric X values; some have textural X values in which case Excel switch to generating 1, 2, 3, ... as X values. When importing to our chart implementation, using "categories" role in such cases instead of "values-x" results in a more faithful chart rendering. Change-Id: If4bc1f650bb024dcd1b1b36537f457fb38404a78
