I think I understand what you are saying, but it still does not make complete sense vis-a-vis my experience with stacked charts. In fact, I am using a custom renderer in some of my charts, so I realize that I can apply that separately for each series: but a stack represents multiple (usually all) of the series together as a single visual item (stacked boxes). What does not seem possible is to apply styles to a single set of the data in the chart (effectively one 'row' of data). BTW, I made a mistake earlier when I said I could get to the individual 'box' element drawn for a chart item. While this might be possible, what I am actually doing is dynamically changing the style on the ColumnSeries. The effect of this is shared across all of the data elements in each stack which are part of that series, but in this case I have a single stacked column so I am able to use it as a highlight effect. oliver
