title: How to create a TfrxChartView in code?
body: <p>I'm using Fast Reports 4.13.1. I need to display a number of charts on my summary band, and I'm trying to dynamically create them in <code>OnBeforePrint</code> event handler of the band. The problem is, while the charts are created correctly, the series don't show the data I'm adding to them. Here's my <code>OnBeforePrint</code> event:</p>
  
  <pre><code>var
    dsSections,
    dsTests,
    dsHistory: TfrxDataSet;
  
    Chart: TfrxChartView;
    ChartCount: Integer;                                               
  begin
    dsSections := Report.GetDataSet('frdTestSections');
    dsTests := Report.GetDataSet('frdResults');
    dsHistory := Report.GetDataSet('frdTestHistory');
  
    ChartCount := 0;
    dsSections.First;
    while not dsSections.Eof do
    begin
      dsTests.First;
      while not dsTests.Eof do
      begin
        if dsHistory.RecordCount &gt; 0 then
        begin
          Chart := TfrxChartView.Create(rsHistory);
          Chart.Left := (ChartCount mod 2) * 8 + 1;
          Chart.Top := (ChartCount div 2) * 5 + 0.5;
  
          Chart.Width := 8;
          Chart.Height := 5;
          Chart.Chart.Title.Text.Text := dsTests.Value('Name');
          Chart.Chart.View3D := False;
  
          Chart.AddSeries(csLine);
          dsHistory.First;
          while not dsHistory.Eof do
          begin
            ShowMessage(dsTests.Value('Name') + #13#10 + IntToStr(dsHistory.RecNo + 1) + ' ' +dsHistory.Value('Result')); // this is for debugging only
            Chart.Series[0].Add(dsHistory.Value('Result'), IntToStr(dsHistory.RecNo + 1), clBlue);                                                                                                                                                                                                                 
            dsHistory.Next;
          end;                                                                                                       
  
          Inc(ChartCount);                                          
        end;
        dsTests.Next;
      end;
      dsSections.Next;
    end;                  
  end;

  <p>What am I missing? Is there any property of <code>TfrxChartView</code> I should set that I'm ommiting?</p>
