Description yeray alonso 2014-10-10 05:19:51 EDT 
As the customer says in the forums, the hover feature is modifying the behaviour of old projects.

We could do what we did with GDIPlus: add an option at the "New Chart" tab in the design time options that writes a key in the registry.
Then Hover could be disabled when this key isn't set, meaning that's an old chart.

The problem with a registry setting is, when the exe moves to another PC, the setting is not there.

This setting could be used for new Charts added at design-time, but not for existing ones.

>>the hover feature is modifying the behaviour of old projects.

Is there any example? Can we fix this?

There is a global per-chart setting to disable Hover:

  Chart1.Hover.Visible:=False;

We can't consider this as a bug to be fixed. It's a new feature important enough to be enabled by default.

We consider we haven't broken backwards compatibility because the charts made with previous versions still work.

And, there's a simple call that can be added to existing projects to disable this feature when undesired.
