I have a series grouped by month.
I want it to sorted correctly.
How?

Hi jls,
If you go to the Series -> General tab how are series sorted? You should try sorting them by text. If the problem persists could you please attach a simple example project we can run "as-is" to reproduce the problem here?
Thanks in advance.

Hi jls,
To achieve what you request you can change your datasource to use a dataset like this:
- jlsDataset.jpg (60.22 KiB) Viewed 16595 times
Which produces this chart:
- jlsResult.jpg (164.6 KiB) Viewed 16614 times
Is that what you were looking for?
Thanks in advance.

No
It should be grouped my month and sorted by month (dec2010,jan2011,feb2011....)
It can be more than one row in each month

Hi Jørgen,
Ok, I see. We have done some modifications to DBChart.pas here that would let you achieve what you request. Since you are a source code customer you could try doing the modifications below to your code. If that's what you are looking for we will investigate further if those modifications can make into a production release.
Go to
TCustomDBChart.RefreshDataSet method, at
AddToSeries a nested method of another nested method(
ProcessRecord), change this:
Code: Select all
ASeries.Add(tmpMand,tmpXLabel,tmpColor);
for this:
Code: Select all
if (GroupPrefix=dgNone) then
ASeries.Add(tmpMand,tmpXLabel,tmpColor)
else
ASeries.AddXY(tmpNotMand,tmpMand,tmpXLabel,tmpColor);
Also, in the same nested method (
ProcessRecord) in
TCustomDBChart.RefreshDataSet method, change:
Code: Select all
if Assigned(tmpData) then
tmpNotMand:=TField(tmpData).AsFloat
// ADataSet.GetFieldData(TField(tmpData), @tmpNotMand) // v7 speed opt.
else
tmpNotMand:=0;
to this:
Code: Select all
if Assigned(tmpData) then
tmpNotMand:=TField(tmpData).AsFloat;
Please let us know if that's what you are looking for.
Thanks in advance.

Better, but the x location of the bars is not correct.
It should not care about the date, just the month.

Hi Jørgen,
With the code as it stands the bars are set at the location of the date of the last value in that month. We assume that you would prefer the bars to centre on that month. Is that correct?
Thanks in advance.

Think it is tha same for me if it is first, midle or last day in the month, the problem is that it doesn't work like this for me. It uses the actual date. Take a look at the second image.

Any solution?

Hi Jørgen,
Yes, we have a new solution proposal. Besides the changes I posted here last week you should also make a change at
TCustomDBChart.RefreshDataSet in
DBChart.pas at its nested
CalcXPos function. You'll need to do the following:
1. Add a
Word variable called
WeekNum.
2. Replace this code:
Code: Select all
dgWeek: result:=TeeStr(DateToWeek(tmpNotMand,Year))+'/'+TeeStr(Year);
dgWeekDay: result:={$IFDEF D15}FormatSettings.{$ENDIF}ShortDayNames[DayOfWeek(tmpNotMand)];
dgMonth: result:=FormatDateTime('MMM/yy',EncodeDate(Year,Month,1));
dgQuarter: result:=TeeStr(1+((Month-1) div 3))+'/'+TeeStr(Year); // 5.02
dgYear: result:=FormatDateTime('yyyy',EncodeDate(Year,1,1));
for this:
Code: Select all
dgWeek: begin
WeekNum := DateToWeek(tmpNotMand,Year);
result:=TeeStr(WeekNum)+'/'+TeeStr(Year);
tmpNotMand := EncodeDateWeek(Year,WeekNum,4);
end;
dgWeekDay: begin
result:={$IFDEF D15}FormatSettings.{$ENDIF}ShortDayNames[DayOfWeek(tmpNotMand)];
DecodeDateWeek(tmpNotMand,Year,WeekNum,Day);
tmpNotMand := Day;
end;
dgMonth: begin
result:=FormatDateTime('MM/yy',EncodeDate(Year,Month,1));
tmpNotMand := EncodeDate(Year,Month,15);
end;
dgQuarter: begin
result:=TeeStr(1+((Month-1) div 3))+'/'+TeeStr(Year); //5.02
tmpNotMand := EncodeDate(Year,((1+((Month-1) div 3)-1)*3)+2,1);
end;
dgYear: begin
result:=FormatDateTime('yyyy',EncodeDate(Year,1,1));
tmpNotMand := EncodeDate(Year,6,30);
end;
3. Finally add
DateUtils at class' uses section.
Which produces this chart:
- jlsProposal.jpg (96.93 KiB) Viewed 16429 times
Is that what you expected? Notice there are some more DateTime grouping options now.

Hi Jørgen,
Thanks for your feedback. We will include this in the next maintenance release then.
