Hi,

I have serious problems with the TLineSeries in the new TeeChart for VCL. Using AddXY to add a point does not work properly. The following code snippet shows an empty plot:

void __fastcall TForm1::FormCreate(TObject *Sender) {

for (double i = 0; i < 10; i++) {
Series1->AddXY(2 * i, i);
}
}


Furthermore, the following snipper raises an EAccessException.

void __fastcall TForm1::FormCreate(TObject *Sender) {

Series1->Clear();
}


As does the following:

void __fastcall TForm1::FormCreate(TObject *Sender)
{
Series1->FillSampleValues(100);
double max = Series1->MaxYValue();
}


Is the TLineSeries completely broken, or am I doing something wrong? I'm using TeeChart 2010, C++ builder XE and Windows Vista.

best regards

Hi again,

an update:

I found the AddXY not working under c++ is already known:
http://www.teechart.net/support/viewtop ... dxy#p51484

However, the fix given there does not work either.

Also, the following functions raises exceptions:
* Series1->Color = clRed;
* Chart1->Title->Caption = "asfsdf";
* Chart1->Title->Color = clRed;


Does not raise exception, but does not do anything:
Series1->SeriesColor = clRed;

I did not test systematically, but it seems a whole lot is not working. A bit too much even, which makes me suspect that there is something wrong with my setup. Could anyone test if the given code works? If there is a problem with TeeChart 2010, is there any way of getting an older version?

best regards

Oh, I'm using the latest (Feb 2011) Pro version of TeeChart.

Found the problem. Include files had to go at the top in c++ builder.

Hi Fredrik,

I'm glad to hear you've found it.
