Lost in Transformation / Scaling

[Nicole]

I have a huuuuge chart and 4 vertical axes. The chart looked nice. Suddenly the time axes collapsed to a certain point. Not sure, what I did. I use TDateTimeIntervalChartSource for the horicontal axes and this works fine in all my charts and worked fine for this one "before".

I found out, that the collapse happens, the moment I set one of the series to active, which have a certain vertical axes.

Code: Pascal  [Select][+][-]

1.    for i := 0 to Length(COT_DisA_) - 1 do  begin
2.  
3.      if series_OPEN_INTEREST.Active   then  // not under comments for testing and now at a 5th axes for testing
4.        series_OPEN_INTEREST.AddXY(COT_DisA_[i].datum, COT_DisA_[i].OPEN_INTEREST);
5.    {  series_PROD_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].PROD_LONG);
6.      series_PROD_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].PROD_SHORT);
7.  
8.      series_SWAP_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].SWAP_LONG);
9.      series_SWAP_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].SWAP_SHORT);
10.      series_SWAP_SPREAD.AddXY(COT_DisA_[i].datum, COT_DisA_[i].SWAP_SHORT);
11.      series_SWAP_LONG_net.AddXY(COT_DisA_[i].datum, COT_DisA_[i].SWAP_LONG - COT_DisA_[i].SWAP_SPREAD);
12.      series_Swap_short_net.AddXY(COT_DisA_[i].datum, COT_DisA_[i].SWAP_SHORT - COT_DisA_[i].SWAP_SPREAD);
13.  
14.      series_MMONEY_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].MMONEY_LONG);
15.      series_MMONEY_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].MMONEY_SHORT);
16.      series_MMONEY_SPREAD.AddXY(COT_DisA_[i].datum, COT_DisA_[i].MMONEY_SPREAD);
17.      series_MMONEY_LONG_net.AddXY(COT_DisA_[i].datum, COT_DisA_[i].MMONEY_LONG - COT_DisA_[i].MMONEY_SPREAD);
18.      series_MMONEY_SHORT_net.AddXY(COT_DisA_[i].datum, COT_DisA_[i].MMONEY_SHORT - COT_DisA_[i].MMONEY_SPREAD);
19.  
20.      series_OTHER_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].OTHER_LONG);
21.      series_OTHER_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].OTHER_SHORT);
22.      series_OTHER_SPREAD.AddXY(COT_DisA_[i].datum, COT_DisA_[i].OTHER_SPREAD);
23.      series_NONREP_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].NONREP_LONG);
24.      series_NONREP_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].NONREP_SHORT);
25.  
26.  
27. all in comment causes the issue and all is added to a certain axes, the values below are another axes and are fine                                                                          }
28.  
29.      series_CONC_4_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_4_LONG);
30.      series_CONC_4_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_4_SHORT);
31.      series_CONC_8_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_8_LONG);
32.      series_CONC_8_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_8_SHORT);
33.      series_CONC_NET_4_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_NET_4_LONG);
34.      series_CONC_NET_4_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_NET_4_SHORT);
35.      series_CONC_NET_8_LONG.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_NET_8_LONG);
36.      series_CONC_NET_8_SHORT.AddXY(COT_DisA_[i].datum, COT_DisA_[i].CONC_NET_8_SHORT);
37. end;  

 


Sometimes I watched this cumulation line-of-points on the time axes "hopping".   
So probably the issue may be a matter of scaling.

Ok, I added a new left axes and found: The cumulation effect of the left axes is healed, - but the independent scaling of the 2 axes is shot.

So the solution is anywhere deep in the interaction of scaling, time axes and transformation, but how to find it?
I add a zipfile showing all three graphic effects and the frame, where it happens. Unfortunately the frame is linked to a database, which I cannot post.

Thank you all for looking at it.
There shall be 2 attachments, which trouble me in uploading.
I try to add one more posting.
