Prevent grouping column header in JasperReports - jasper-reports

i want to make an Crosstab Template for my data.
For each value there is a timestamp, a location and the name of the device from which i get the value. So i am giving a list of values via Java and a JRBeanCollectionDataSource to my report, for the example below this would be 9 values while each of them has 3 additional parameters to place it on the right column/place in the crosstab.
When i give this sort of data to my Jasper Report with a Crosstab (Crosstab is needed cause i don't know how many rows and columns my report will have) in it, Jasper orders/groups the columns and the output looks like this:
But what i want is to show the data in the sequence i give them to my report, for example:
I am using Java to fill my report with a JRBeanCollectionDataSource and a self defined DataSource (this works perfect, i am working with this method for months).
Is there any way this kind of column grouping could be prevented? (i have a working crosstab template but i am not able to find the propertie with the help of i can solve my problem)
Hope you people can help me.

Have you tried to tell the crosstab that your data ir already sorted?

Click the crosstab element, in the Dataset Tab, mark "Data Pre Sorted".

jasper report show count on footer of a specific query

am very new to jasper report
also I have tried looking at videos but can not seem to get this one concept
basically there is this main query which i have
select * from table
which is populated in the details area
however i want a second query
select count(*) from table where name = "tim"
and put the count on the footer
can this be done using jasper
any tutorial to this concept or guidance would be helpful
to sum up the details area should show all the data where as the footer should only show counts of a few things.
You can only have one DataSet (therefore query) for the report. In your case this is your main report select * from table, which seems to be working well.
You have two options for adding the information you want:
(and I would say the better option) is to add a variable $V{tim_count} which is configured as:
initial value 0
expression value "tim".equals($F{name}) ? 1 : 0"
calculation function sum
there are multiple ways to increment this variable, so I'll leave that with you. In the footer you would then add a text field with the $V{tim_count} variable as it's contents.
You can read about variables here https://community.jaspersoft.com/wiki/variables
You can add an object that has it's own DataSet:
Table
List
Subreport
You would then be able to add your query to that object and display it appropriately. As you can see, displaying a COUNT is not really the most appropriate way to do this.
Note - I don't suggest this way

Items in details repeating itself in Crystal Reports

Situation
I got stucked to some weirdo in Crystal reports. See the image below of my RAW RPT.
Everything in my report is coming fine except the details part. You can see there DetailsSection6, in which i have few columns(10-15). This rpt is binded with the XSD file and that XSD is then binded with its concerned dataset at runtime. Dataset has around 10 tables from which two tables are concerned here.
PROC_CONS_SUBBILL_REPORT - Header Table with single row.
CON_T_SUBBILL_DTL - Detail table having multiple rows based on the VoucherNo of above table.
What I want
I need to display all records of detail table in tablular format based upon the VoucherNo. Say in detail table (SUBBILL_DTL), I am having 25 records, but when table is rendered on the rpt, its starts repeating itself, sometimes twice sometimes thrice.
Kindly note:
My SP is returning the expected and correct data
RPT has 5-6 SubReports and in one report PROC_CONS_SUBBILL_REPORT table is used.
There is no Relationships in the report in the form of keys.
What I did
Tried removing all keys between the tables.
Suppressed the Detail Section but it suppresses the entire data.
Suppress the detail section with formula
{CON_T_SUBBILL_REPORT.CODE}=previous( {CON_T_SUBBILL_REPORT.CODE})
but still its not working.
I am totally lost. Kindly help.
Normally records are duplicated when the linking is wrong, In your case instead of formula try to use the option Select Distinct Records under Database tab.
This is a little late, but in case somebody else is looking for an answer.
I tried all the things above and nothing worked. Crystal reports was changing my query.
It worked in SQL Server but not in Crystal Reports.
The way I fixed it was by creating a view of my query on Sql Server and using the view
in my Crystal Report. It fixed everything.

Jasper Report group subreports using columns

I have a master report (using iReport 5.0.4) with a subreport that uses grouping by a field called "Group Number" (sorry, but that is the actual column name).
My report works fine when there are more than one group, but it generates each group result scrolling down the page vertically.
I would like to be able to have each group go across vertically, but when I tried using columns, it simply forces each group's data into columns, and not the entire group 1, followed by group 2 in the next column, etc.
There can be up to 8 groups, so I was hoping not to have to create 8 individual sub-subreports with a "print when" expression to show/hide them.
Can anyone tell me if this should be possible?
Thanks,
Mitch
I think making subreports is the easiest and obvious way. But if you want to make it in other way, I can only suggest to use scriptlet, and form dataset manually (Transpose it).
Another suggestion is when you generating report directly from database (i.e. passing connection into jasper) you can modify query and transpose the data (PIVOT table).
Anyway provide more info about your case. I will try to help you.

How to make the following report using Jasper Reports

I collect test results between different locations. I can never predict the amount of locations that I should generate the report for and I need to make a dashboard representing these results. The dashboard should look like this (Assume a tabular structure):
Title
Report info 1|Report info 2
Conditionally displayed report (info 3) spanning the whole table columns
Report info 4|Report info 5
Blank Cell|Location A|Location B...etc
Location X|X-A result|X-B result...etc
Location Y|Y-A result|Y-B resutl...etc
.
.
etc
I've read A LOT and after a lot of reading I still don't think I can start making a JR report !
Although, after a while of chasing the solution of doing so using tables, I found that I should use crosstabs instead because tables aren't dynamic enough (i.e. since I can't predict the amount of rows\columns that will need to be displayed). But then after reading the crosstabs section I found that it's purpose is to summarize results, like calculate totals, averages, minimum and maximum..etc and still, that's not what I need. I'll have to provide all the results locations on the x\y axis and their results, no SQL will be involved.
Also what data structure would be suitable for that ? A datasource ? A java collection\object passed as a parameter ?
Any idea how can I do that with JR ?
Also a I'm finding JR VERY confusing and complicated. I was very happy to read the freely available ultimate guide and check the demos but that didn't help much, it still looks very complicated !
Thanks in advance.
if you cannot predict the amount of columns, crosstabs are the elements you have to choose. But be aware, that the width of a Jasperreport is static (and like this possibly not optimal for your purposes).
A crosstab will summarize your data only, if you have a column or row label twice, and only if the data is not sorted by the crosstab itself or by your datasource.
According to your description, I would use a report layout like
Title-Band: Title, Infos etc
Summary: Crosstab
You could pass the static title content as parameters into your report, the crosstab content as a datasource (e.g. a bean collection)

Crystal Reports: Cross-Tab Column Arrangements

I am looking for a way out in cross tab, so that if the columns exceed in cross tab, they shouldnt go on next page..rather a new cross-tab should repeat after the first one.
For example, two columns are displayed in a cross tab :
Now if a new column is added, and assuming that it could not be accomodated within the given page width limit, it will go to a page next to it in CR by default.
But in my report it is required to be shown below the first cross tab (and not on next page), which will look as follows:
Please do suggest me if there's a way out :)
Thanks in advance
Your question is perfectly reasonable, but I'm pretty sure that in CR-XI, there is no automatic way to do this. I recommend skipping the cross-tab designer completely and just making your own:
Make a new CR using a placeholder table that has exactly 1 record.
In this CR, suppress everything but the details section. Add a new details section so you will have Da and Db.
In Da, add a subreport. Use your real datasource and add Column1 and Column2.
In Db, add a subreport. Use your real datasource and add Column3 and Column4.
I don't have time to test this, but I think it will display all the columns as you requested.
(Instead of step 1, you can probably use a placegrouper group in your report that only has 1 group. Then, when you add the subreports, make sure to not add any links to the main report.)
Edit
A dynamic number of columns makes this request much more difficult to do in Crystal.
Maybe you could autogenerate the entire report from a script. I couldn't help you with that, but I'm sure someone else on StackOverflow will.
You can use MS Excel to achieve something similar. Use MS Access or something similar to set up a crosstab of your data. Open a new Excel workbook and import your crosstabbed datasource using Data->Import External Data->Import Data (this imports the entire table, regardless of number of rows). In Page Setup, change settings to Fit to (blank) pages wide by 1 pages tall. You can format the data however you like and the format will be retained. This Excel method will squeeze all your columns into a 1-page wide area. It's not quite what you're asking for, but it will work.
The number of columns may be dynamic, but do you know what the field names could be? For example, your columns include 0-50 US States, then you know what the column names will be, just not which ones or how many. If this is your situation, then use my first suggestion (check off the suppress if blank options to hide unneeded subreports). It won't be pretty (alot of white space), but it can get the job done.
A possible solution can be a multi column report. But it can be difficult to make the row labels and values in the same line.
If you can create an additional row grouping then you have the solution that you want. For example if your columns have number like in your sample. Then you can add a formula like:
columnId \ 2
