Re: Real-Time charts

[User (Legacy)]

Yes, NSeries is the total number of series.  If you examine it under the 

scenario I mentioned (setting NSeries to 20 in design time and back to 2 

again) you'll see that NSeries stays at 20 - a good indication that the 

component has pre-allocated 20 and not returned to 2. 

Deleting and reinserting the component has no effect - I've already done it. 

Note also that I'm inserting a series into a real-time chart - they're won't 

be any history for the series, just new data going forward.

Is the nSeries the Total number of series?  If you had 1 series and wanted 

to add 1 more nSeries would now be 2. 

The following bit of code works for me in Access2k.  Sometimes before I go 

"over the edge", I delete the control and reinsert it.  Seems to help.

Private Sub Form_Load() 

    'set chart with 1 series 

   ChartFX1.OpenDataEx COD_VALUES, 1, 5 

   ChartFX1.Series(0).Yvalue(0) = 30 

   ChartFX1.Series(0).Yvalue(1) = 76 

   ChartFX1.Series(0).Yvalue(2) = 43.5 

   ChartFX1.Series(0).Yvalue(3) = 90.75 

   ChartFX1.Series(0).Yvalue(4) = 12.5 

   ChartFX1.CloseData COD_VALUES 

End Sub 

Private Sub cmdAdd_Click() 

    'add another series to existing chart 

   ChartFX1.OpenDataEx COD_VALUES, 2, COD_UNCHANGE 

   ChartFX1.Series(1).Yvalue(0) = 40 

   ChartFX1.Series(1).Yvalue(1) = 86 

   ChartFX1.Series(1).Yvalue(2) = 53.5 

   ChartFX1.Series(1).Yvalue(3) = 100.75 

   ChartFX1.Series(1).Yvalue(4) = 22.5 

   ChartFX1.CloseData COD_VALUES 

End Sub
