Hi Ingrid, I appreciate your reply & interest to help in our project.our project scope is more interesting .i'll explain it below.at this stage i'm trying to discover the new chart2 API which still remains obscure to me.i'll need some time to understand well the structure of this chart2 module.your feedback in mailing list was quit helpful to get started. I hope you will continue supporting us during our project. I hope you don't mind i discuss with you my project goals for you are the OO chart expert & your advise will be very helpful to me. actually our project aim is to extend the openoffice.org com:sun:star:chart2 module using java and openoffice.org UNO API.
we believe The charting component in OO could be improved and we are looking at ways to improve it to match the functionality of Excel. we are considering looking at com:sum:star:chart2 because we feel that SUN had already work on com:sum:star:chart2 for more than 2 years and they have already developed most of the infrastructure, what it needed is a way to extend it in UNO to suit my need. our first aim is to use the chart2 API to programatically draw an OO combined chart .( candlestick chart combined with line chart in same graph ). a second project iteration will be to create and deploy a new java OO UNO service that extends com:sun:star:chart2 by adding the new chart type (CandlestickAndLineType). i think that Netbeans OO Integration tool provide easy features to create and deploy a new OO service. 2) we also thought of a second approach : It seems to me that in OO UNO all it matters is the interface. Therefore if i can redefine the interface, i may even use the jfreechart library behind the scene to draw the chart in the canvas. what do you think of this approach ? can you give me Ideas how to marry the OO chart API with the jfreechart library ? (http://www.jfree.org/jfreechart/ ) if i use the jfreechart library, i need a way to map the spreadsheet data to the format expected by jfreechart. I believe i need to marry the jfreechart with chart2 in UNO. The jfreechart library is a good candidate to physically draw the chart in the canvas while the chart2 interface already have the infrastructure in place to understand the data in the spreadsheet like range, columns etc. can you please advise us how to rewrite the UNO interface so it can use jfreechart behind the scene to draw the complex chart type (using java ) ? I Hope i could receive advice, Ideas and hopefully some sample java code from you Regarding this project. -- View this message in context: http://www.nabble.com/combined-chart-type-using-com%3Asun%3Astar%3Achart2-tp19003238p19159774.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]
