Description
[iOS]
TeeChart is very slow on my iPad3. It uses 20 sec to rotate.
The iOS simulator works OK.

To reproduce:

Create a simple project like this

procedure TForm1.FormCreate(Sender: TObject);
begin
FChart := TChart.Create(Self);
FChart.AddSeries(TBarSeries);
FChart.Align := TAlignLayout.alClient;
FChart.Width := 400;
FChart.Height := 400;
FChart.Series[0].FillSampleValues(9);
FChart.Parent := self;
end;


Also reported it on Teechart support forum:

and the answer is that FireMonkey iOS must improve it's performance on iOS.
Steps to Reproduce:
create the test application and run it on an IOS device

Are you using TeeChart Pro?
Have you already contacted technical support of Steema?

> create the test application and run it on an IOS device
and, could you please attach sample project to reproduce/confirm your issue?
