Description sandra pazos 2017-01-02 10:31:18 EST 
The Chart Draw method causes an EInvalidOperation Excetpion. The problem doesn't occur using Steema TeeChart Pro VCL/FMX 2016.18 when the chart is drawn in GDI. In latest Teechart release the problem is produced always. 

The code below shows the problem:

uses Series, TeEngine, TeCanvas, Chart;
var Chart1:TChart;
procedure TForm1.Button1Click(Sender: TObject);
begin
  Chart1 := TChart.Create(nil);
  Chart1.Color := clWhite;
  Chart1.Canvas := TTeeCanvas3D.Create;
  Chart1.Draw;
end;
