I'm drawing a stacked bat chart, with a single bar and a variable number of "slices". So a bit like a pie chart but as a vertical rectangle. I find I need to dynamically add TChartStyle items to the TChartStyles component I am using. This seems necessary ij order to get the legend having the correct number of entries. My problem is that I cannot find the relevant "Clear" and "Add" methods for the TChartStyles. Each time the chart is drawn I want to delete all styles from the TChartStyles and then add a TChartStyle for eacj slice that I am adding to the bar. Can you tell me the methods to do this please?
