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.

here is a sample

Hi jls,

To achieve what you request you can change your datasource to use a dataset like this:

: jlsDataset.jpg (60.22 KiB) Viewed 16698 times

Which produces this chart:

: jlsResult.jpg (164.6 KiB) Viewed 16717 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?

Posted: **Thu Sep 29, 2011 3:21 pm**

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 16532 times

Is that what you expected? Notice there are some more DateTime grouping options now.

This is exactly what I want,
Thanks

Hi Jørgen,

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