Data source

Is there a possibility to share the data in my internal data structures with a Series, so that my program internal data and the Series data are consistent? I see it is possible with a database or a file, but I want to use only memory.

Does Series copy the data or access it by reference?

Hi deha,

To achieve that you should define an event for your recordset being updated and call series' CheckDataSource method there.

Hi Narcís, thanks for your answer.
How do I tell a Series where the data is found? Like CheckDataSource says, it check the data source. As written in documentation DataSource may be a database or an other Series. But I want to use my memory data structure. Any ideas?

Hi deha,

In that case you should manually iterate through your data structure and populate TeeChart series using Add/AddXY methods. Assigning a database datasource does the same internally.
