The easiest way may be to create two graphs for the data, identically sized and labeled, so that they can invisibly overlay each other. Chart the pre-1998 data on the first graph, and set its build so that all the lines build in together. Chart the later data on the second graph, setting it to build in each line separately. This should give you the effect you want.
