TChartSeries.Assignformat uses unsafe Assignment

TeeChartSeries.AssignFormat

Can you change following 4 lines

Self.FHorizAxis := FHorizAxis;
Self.FCustomHorizAxis:= FCustomHorizAxis; // 6.01
Self.FVertAxis := FVertAxis;
Self.FCustomVertAxis := FCustomVertAxis; // 6.01

Into

Self.HorizAxis := HorizAxis;
Self.CustomHorizAxis:= CustomHorizAxis; // 6.01
Self.VertAxis := VertAxis;
Self.CustomVertAxis := CustomVertAxis; // 6.01

In order to make sure the Assign method is called? This is required to ensure (reloaded) series will be linked onto the correct axis.

Thanks for your suggestion Hans.

I've added your request to our wish-list to be reviewed and considered for inclusion in next releases.

Actually, it is a bug present from teeChart 5 already.

When loading chart settings, the chart becomes the 'owner' of the Tpersistent derived objects from another chart, causing AV's later on when the other chart is freed!

I guess I'll have to keep my patch for now...

Hi Hans,

Could you please send us a simple example project we can run "as-is" to reproduce the problem here?

Thanks in advance.

I am currently under some time pressure.

This problem, however appeared during Teechart5 days when assigning a TChart (and copying series) to a TQRChart. My problem demo project got lost somewhere in time...

I'll let you known asap when I have some mini project to demonstrate the problem.
