Hi,

I create a certain amount of CustomAxes in my TChart, e.g. by using: However, it's not clear to me whether I need to destroy (Free) these axes myself or is the parent chart (MyChart) taking care of this?

In my Project Source I have If I don't explicitely destroy the CustomAxes, no leaks are reported. However, I cannot find anything in the documentation. Can you please advise on the correct approach to remove (destroy) all CustomAxes? Is there something like: or should it be
Thanks,
Mark

Hello Mark,

CustomAxes is a public property in the TCustomAxisPanel (and derived such as TChart) to access the private FCustomAxes : TChartCustomAxes property (TChartCustomAxes, inherits TOwnedCollection).
Indeed, at the TCustomAxisPanel.Destroy destructor method, the CustomAxes are freed:

Clear, thank you! It's a bit counter-intuitive (typically manual creation requires manual destruction in Delphi) so perhaps an idea to add this to the documentation?

Hello,

Note the CustomAxes (and many other objects) can also be created at design time or at runtime via the editor. So I guess that would be an obstacle to that "manual creation requires manual destruction" rule.
But yes, I'll check if we can add a note somewhere in the docs.
