How to Stack ScatterPlots in Categories ?

[MarkU]

Hi, I’m trying to create a single chart with a X-axis of Categories; each Category then contains up to three Series of Y-axis data to be expressed as a Scatterplot (actually a vertical scatter-’line’) or XYLineChart. In principal this is not very different to a simple stacked barchart (e.g. StackedBarChartDemo1) BUT with each bar segment replaced with Series data. Any ideas how to go about this ?
