I am wanting to use the TPolygonSeries, used by TMapSeries. I am getting an access violation error when assigning to the chart yet the
parent chart series TChartSeries will assign fine. What is the problem.

PS I don't want to use the TMapSeries as I wish to inherit from TPolygonSeries and add my own functionality.

Hi InfoDeck,

Sorry but we don't provide support for sourcecode modifications. However, if you can reproduce the issue using the binary release of TeeChart please send us a simple example project we can run "as-is" to reproduce the problem here and we will investigate it.

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi Narcis

I don't understand your response. I'm not altering any source code simply
attempting to use the existing TPolygonSeries which is a valid TChart series and iherited from TChartSeries ?? Surely you shold be able to use this series?

Hi InfoDeck,

I'd like to apologise if I didn't express myself correctly. I don't think doing what you are trying to do is not valid but we can not commit to provide technical support to TeeChart customisations. Anyway, would you be so kind to provide a simple example project we can run "as-is" to reproduce the problem here?

Thanks in advance.
