Thank you , that did the trick ! However there remains a small issue : for candlestick chart only the series with Role "values-last" is displayed in legend. it is labeled "Close". so why the chart doesn't display the other candle series with roles "values-max" ,"values-first" , "values-min" ? it seems for candle chart only the "close" series are displayed in the legend. is there a way to add the other candle series to legend entries ? thanks much. othman. -- View this message in context: http://www.nabble.com/discussing-com%3Asun%3Astar%3Achart2-API-tp19268400p19435378.html Sent from the openoffice - api dev mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
