  We can easily see a 'part-of-a-whole' methodology being used here as well-we are seeing the breakdown of Segments within each Category.

  To easily visualize trends over time-This is the definition of a line chart. To visualize each discrete category using a separate bar-This can be accomplished using a simple bar chart, why use a stacked one?
