I have a measure grouped by year. How can I calculate the differences between the two years?

I need ventas(2024) - Ventas(2025)

thank you

The reason this topic is of concern to me is a problem that I just fixed.

I am in the process of converting code to Fast Reports that formerly used Quick Reports. The code I just converted began producing range errors because of accesses to an empty list that should not have been empty.

The problem was due to my cleanup code in the OnAfterPrint event. In Quick Reports, this event is not triggered until the report was finished printing. In Fast Reports, this event is triggered even before the 'First' event! I fixed the problem by moving the cleanup code to the OnEndDoc event.

This problem was particularly insidious because the OnAfterPrint event code had not changed. I spent much time scanning the code that I had changed for the cause of the problem.

I'm trayiing to change the format of a measure to a custom format. How can I do it? I selct custom but in format teaxt I can't write

Thank you

I use FastReport and FastCube Ultimate in Delphi 11.2, but I can't find the "Formular Editor" for Input PascalScript in FastCube. In the documentation sehr ist only a picture, but not more information.

Thanks for help

I am testing FastCube.NET trial version. When I load data programmatically and setting up axes and measures, the horizontal header of the grid is cut off. The curious thing is that when I am trying to change the height or the width of one of grid's columns by dragging the column edge, even a little bit, the header "unfold" and has the right height.

The code:

var list = new List<TestModel>

       {

         new TestModel{ Count = 1, Date = DateTime.Now.Date, Name = "Test", Kind = "K1" },

         new TestModel{ Count = 2, Date = DateTime.Now.Date, Name = "Test", Kind = "K2" },

         new TestModel{ Count = 3, Date = DateTime.Now.Date, Name = "Test", Kind = "K1" },

         new TestModel{ Count = 4, Date = DateTime.Now.Date, Name = "Test2", Kind = "K2" },

         new TestModel{ Count = 5, Date = DateTime.Now.Date, Name = "Test2", Kind = "K3" },

         new TestModel{ Count = 6, Date = DateTime.Now.Date, Name = "Test2", Kind = "K1" },

       };

     cube1.Close();

     cube1.SourceType = SourceType.DataSource;

     cube1.DataSource = new FastReport.Olap.Cube.DataSource()

     {

       DataSet = new FastReport.Olap.Cube.ListDataSet()

     };

     (cube1.DataSource.DataSet as ListDataSet).DataSource = list;

     cube1.Open();

     slice1.MeasuresContainer.AddMeasure(new MeasureField(slice1)

     {

       Name = "Count",

       Caption = "Count"

     });

     slice1.XAxisContainer.AddMeasuresField();

     for (int i = 0; i < list.Count; i++)

     {

       var filterField = slice1.SliceFields.GetFieldByIndex(i);

       slice1.FiltersContainer.AddSliceField(filterField);

     }

     var field = slice1.SliceFields.GetFieldByName("Name");

     slice1.YAxisContainer.AddSliceField(field);

     field = slice1.SliceFields.GetFieldByName("Date");

     slice1.YAxisContainer.AddSliceField(field);

     field = slice1.SliceFields.GetFieldByName("Kind");

     slice1.XAxisContainer.AddSliceField(field);

I've tried to follow this tutorials ( https://www.fast-report.com/nl/blog/show/using-fastcube-multidimensional-data-analysis/ ).

Since I want to connect PostgreSQL via FDConnection / FDTable.

I can make things work so far, except the date fields.

No matter how I setup pgsql field "date" to be "date" only or "timestamp without timezone", I can't make this date field automatically create "DayDate", "Monthweek" , etc. like the tutorial

What should I revisit and take a look again? So far, I didn't add any customcode yet.

This is the database table setup

This is the Fields setup and result when I run the project

Hello guys,

I have a populated grid and I need to click on the - sign of the item it shows the data in the line, it being in the collapsed state.
How can I do this programmatically?

How I can do this type of report in FastReport?

I need a code that allows me to reach a page on memoclick event. my first page is like a summary I want to allow the user to reach the desired page by clicking on the chosen memo. get to the page a memo (summary) allows the user to return to the summary

when compiling the program gets such an error :

[dcc32 Fatal Error] Unit7.pas(8): F2051 Unit fcxFilterPopup was compiled with a different version of fcxMeasureEditor.TfcxMeasureEditorForm

how to solve it ?

FMX is the only way to develop both for Windows and OSX!

Once we have installed FastCube 2 VCL Trial version on delphi XE8 we have checked the demos and they are working without problems, but when we create a new form on a developed vcl application with a fastcube it raises the following error:

[dcc32 Fatal Error] RejillaBITTOLAP.pas(14): F2051 Unit fcxFormats was compiled with a different version of fcxTypes.TfcxDateTimeConsts

We want to try the cube first on our application before to purchase it but we can't try on this way. What is wrong? thank you very much.

I did open one of the datasets and work with data, thitching raises an erroren saved it onto a cube file. After, I did the same with the other dataset. Now, I open the cube file of the first dataset and work with it and could see their field list, then I open the other dataset, but in this case I reach the following error message on the last line of the code: "FastCube error: Field CODIGOPRODUCTO not exists in DataSet fcxDBDataSet1;" as if the fcxCube remains with the previous dataset.

How could I solve this problem and switch between these two dataset's or more?

This is the code that I'm using:

fcxCube1->Close();
fcxDBDataSet1->DataSet = NULL;
PanelCubos->Width = PanelGraficosCubos->Width - 20;
if(RG_TipoPivot->ItemIndex == 0) { // Caso Compras
   DM_FRep->IBQ_VistaDetComprasIngred->Close();
   DM_FRep->IBQ_VistaDetComprasIngred->Params->ParamByName("INICIO")->AsDate 
      = StrToDate(F_Inicio);
   DM_FRep->IBQ_VistaDetComprasIngred->Params->ParamByName("TERMINO")->AsDate
      = StrToDate(F_Termino);
   DM_FRep->IBQ_VistaDetComprasIngred->Open();
   fcxDBDataSet1->DataSet = DM_FRep->IBQ_VistaDetComprasIngred;
} else if(RG_TipoPivot->ItemIndex == 1) { // Caso Ventas
   DM_FRep->IBQ_VistaDetHistVtasProd->Close();
   DM_FRep->IBQ_VistaDetHistVtasProd->Params->ParamByName("INICIO")->AsDate = StrToDate(F_Inicio);
   DM_FRep->IBQ_VistaDetHistVtasProd->Params->ParamByName("TERMINO")->AsDate 
      = StrToDate(F_Termino);
   DM_FRep->IBQ_VistaDetHistVtasProd->Open();
   fcxDBDataSet1->DataSet = DM_FRep->IBQ_VistaDetHistVtasProd;
}
fcxCube1->Open();

Having a cube with a Quarter dimension and a Net price measure, I would like to add a calculated measure that calculates the portion of a dimension versus the same dimension subtotal:

It is possible?

It is possible to do the same on totals and grand totals too?

And, if it is, how?

Thanks in advance.

Lorenzo Radice

Having two dimensions (Year and Quarter) and one measure (Net price), it is possible to add a new calculated measure (Delta on previous year) that calculates the increment of a year versus the previous?

Here the formula used to calculate Delta on previous year: ((Field A - Field B) / Field B)

Thanks in advance.

I am using FastCube 2 + Delphi 7

I need to do this VIA code:

I have 3 measures

Measure1, Measure2, Measure3

I need to update/change the total/subtotal of Measure3 to be: Measure1total / Measure2total.

I need to calculate TOTALS only from measure1 and measure2 and then insert that calculated total into a MEASURE 3 total field.

Is this possible? Please I need this urgently

Thank you in advance

I have many measures in my Cube report and I would like to 'separate' them, 'organize' them, 'group' them together, like on this table generated in Excel.

In this example I grouped the columns by continents... is it possible to do this kind of banding or grouping together in Cube?

I mean in code! I am using Delphi 7 + FastCube2. Is it possible to make it with code in Delphi?

Thank you in advance!

I am reposting this question again. Is there anyone who could help me with this problem?

I am using Delphi 7 and FastCube 2.7

I need to hide the total for one measure via code. How do I do it? Thank you!

I have a Cube and I have to hide Totals for a measure. How do I do it?

Can anyone help me? Thanks in advance

I just recently purchased your product Version 2.11.2

I have a laptop computer that I do my development work on. 

When I open my Cube, the Fast Cube displays as compressed and barely readable with a 3840x2160 screen display resolution. I have my VCL Form "Scaled"=True. All other VCL components (that are not Fast Cube) on the form show in a scaled manner.

Items that are not scaled are SliceGrid (Fields, Measures and the Grid), SliceGrid Toolbar.

How do I address the issue of scale for FastCube

I have a cube that calculates the measures based on slicefields. Each measure could be different based on the current Date, it is a 12 month rolling period.

The TMeasure has a CAPTION property, is there a way to set the caption using something like

Measures['CurrentPeriod'].Caption = 'October 2020';

Tried as part of the measure calculation but it doesn't appear to set.

Thanks

Simon

Can you help me. How to change localization language for FastCube.net?

will these cool new Functions be available in FastCube FMX too?
