Hello,

Probably a really basic question, but the Delphi-only helpfiles/example code
for TChart make it very difficult for a C++-only user to understand. I am
trying to add a TLineSeries to a TChart at run time. The Delphi help says
to use:

procedure TForm1.Button2Click(Sender: TObject);
var tmpLineSeries:TLineSeries;
begin
tmpLineSeries:=TLineSeries.Create(self);
Chart1.AddSeries(tmpLineSeries);
tmpLineSeries.FillSampleValues(10);
end;

I tried to implement this as:

TLineSeries *tmpLineSeries = new TLineSeries;
Chart1->AddSeries(tmpLineSeries);

but then using either
tmpLineSeries->Clear();

or
tmpLineSeries->AddXY(1,2);

causes my program to crash! There appears to be no C++ equivalent of
TLineSeries->Create(); used in the Delphi example code.

Anyone able to provide a quick set of C++ example code for adding series to
TCharts?

Thanks,

Ben.
