Scaled time series?

  Hi.
  
  To ignore null values use property TfcChart.SkipNullPoints.
  But You need to fix fcChart.pas:
  

  procedure TfcCustomChart.SendChartData(ATypeChartData: TfcTypeChartData;
  ... line 864
        if (TVarData(AValues[i]).VType in [varEmpty, varNull]) then
          Series[i].AddNull(AStr) // !!! fixed from Series[ASerIndex].AddNull(AStr)
        else
        begin
          if Series[i] is THorizBarSeries then
            Series[i].AddX(AValues[i], AStr, clTeeColor)
          else
            Series[i].AddY(AValues[i], AStr, clTeeColor);
        end;
  ...
  ... line 890
        if (TVarData(AValues[i]).VType in [varEmpty, varNull]) then
          Series[i].AddNull(AData1[i])  // !!! fixed from Series[ASerIndex].AddNull(AData1[i])
        else
        begin
          if aSeries is THorizBarSeries then
            aSeries.AddX(AValues[i], AData1[i], clTeeColor)
          else
            aSeries.AddY(AValues[i], AData1[i], clTeeColor);
        end;
  ...

  Hi Oleg
  
  Thanks for your reply regarding the null values. Do you also have a suggestion for my question regarding time series?

  Hi Oleg
  
  Tried your suggestion regarding null values, and it worked fine.
  
  Have you had time to think about my other problem? I really need the possibility to scale the axis intervals according to the distance between the labels, as I wrote in my first post.
  
  Hope you can help me!
  
  Have a nice weekend
  
  Best Regards

  Hi.
  
  There is no way to do it in FastCube 1.

  Hi Oleg and CM
  
  I have "solved" this problem by making alterations to fcChart.pas:
  
  1) I have added the properties IsXYChart, XIsDateTime and YIsDatetime
  2) I have altered the SendChartData routine, so that if the IsXYChart property is set and the series is Line or point, it tries to convert aStr to either datetime or float (depending on whether XIsDatetime or YIsdatetime is set), and then Calls AddXY instead of AddX/AddY
  3) I also set the datetime property on the series.xvalues and series.yvalues according to the XIsDatetime and YIsDatetime properties.
  
  These alterations are of course complete hacks and only works under given circumstances. The best would be to alter the input parameters to the SendChartData routine so that we dont have to convert a "legend" string into something, but already know the datatype. Here, it should also be possible to detect the datatype of the series, so that its datetime proerty can be set automatically.
  
  Can we hope to see something like this in FC2, Oleg?
  
  Best Regards
  Kristian

  Hi Kristian.
  
  Please send me the modified modules.
  I will analyze and update the FC1 and FC2 to support Scale time series.
