Many thanks Narcís I have found the SaveToStream and LoadFromStream in the TeeStore unit. However, I need to save these to an XML document but the .tee format contains characters not allowed in XML. As a result I get an error when I try to write to my XML document. Is there another format I can save...

Is it possible to deafult the datasource to dataset and set the dataset value automatically when a new series is added to a chart?

Is there a way to limit the datasets in the drop down list?

many thanks

Is there a way to save the specification of a chart (Datasource, series, Titles etc) rather than the whole chart?

many thanks
