In excel charts, you plot several columns on the Y axis and then specify the line style, marker style that you desire, and the style can be completely different for each columns. For example, choose one line to be dotted and another only showing markers. Currently in Spotfire, you can choose to show/hide markers for all the columns together, or show/hide lines of all the columns together. You can not individually choose the style of each columns. So, this idea is to enhance the plotting capabilities of Spotfire to be able to do what simple excel graphs do already.
