How do I merge cells for specific rows in BIRT? Something similar to using colspan when creating a table in HTML. The data is extracted from a database and returns a fixed number of rows.
Specifically I want to convert a BIRT report that looks like this:
to this:
Thank you for your assistance.
I don't know if it is possible to do this within an onCreate event for the cells.
But depending on your use case, it may be sufficient to duplicate the detail row.
Keep the cells as is in the first detail row and merge them in the second row.
Determine a condition when to merge cells and when not.
Use this as an visibility expression for the first and second detail row like this:
First row: should_merge(...)
Second row: !should_merge(...)

I am working on a BIRT report. Its records are grouped on the basis of the status column. I was looking for an option in the Eclipse BIRT tool by which I can hide combinations of multiple columns in a row which are repeating. I have attached screenshots for both the current report and the expected report structure.
I tried the "suppress duplicate" option but that is limited to a single column. I am not able to apply this on multiple columns together. I couldn't figure out any other option. Please suggest any solution in the tool or do I need to change my query to return the result in the expected format?
Actual Result:
Expected Result:
There are three obvious ways to hide duplicate values.
All of these require you to configure this per column (BTW I don't understand why you consider this to be a problem).
As you already did: Use "suppress duplicates" at the column level.
Add more groups to your table after the existing group.
E.g. one group for the first column (whatever that is).
Then you can choose "Drop" "detail" in the properties of the corresponding group header cell. It's a bit difficult to get the layout right this way.
In your data set, if it's SQL, you can use a little construnct with CASE and the LAG analytic function to compare the column value to that of the previous row, and if they are equal, return NULL instead (pure SQL solution).
Good afternoon!
I have created a report with the wizard to create a matrix that is grouped and has drill down rows. I have added filters to the rows and columns and it works great! I then copied that matrix and modified the filters, so I had two matrixes.
But what I really wanted was those two rows in the same matrix, just in different row groups. So I added another group, using the adjacent below option, and then added all the child groupings. However, when I run the report it shows the values for the first row of the drill down data.
When I look at the groupings I can see the one I did manually has a 'Static' field in each row grouping but the ones that the wizard did (with the red ?), they don't have that "extra" row:
What do I need to change or how do I need to add my groups so that I don't get that "static" row and not show the data? I have the visibility set to 'Hidden' and the toggle set up for the prior grouping set data.
Assuming a few things....
the data comes from a single dataset
You are differentiating between Property and Violent crimes by filtering on a column, I'll call it IncidentGroup for the sake of illustration..
I've understood your question ! :)
Get to the point where you had just a single tablix filtered to show 'Property crime'.
Now remove or edit that filter so it shows all the data you need in the report.
Finally, right click on your Matrix1_IncidentCategory row and add a parent group, choose IncidentGroup (or whatever the column is actually called) and check the box to add a group header.
That should be it, there is no need for a second tablix.
Without knowing how you are filtering currently it's hard to give a complete answer but this should get you close, if not all the way there.
If this doesn't work for whatever reason, please post sample data from your dataset output and your current filters.
Everything except for the name may or may not be different, but it doesn't matter.
How do you make it so the name and address (first column) can only show once if the value on multiple rows is the same? There is no way to merge the rows together due to the numbers of rows being generated from a group expression. But if there is another way to merge then can someone tell me how to do it? If not, then is there at least a way to blank out the second and third repeating names (and address)?
This is how you hide repeating values in a tablix column.
In design mode, click on the detail cell that you want to keep from repeating if the values are the same. In this case, you are referring to that one as the name and address column.
Look for the HideDuplicates property in the Properties pane. Set the value to the name of the dataset the tablix is using.
Now, when you run the report, that value should only show once. The other rows where the value had been repeating will be blank in that cell.
Set the borders appropriately (none, or solid) to make it look like the cells are merged. Doing the above alone will not merge the cells. Only a row group will do that.
I have a matrix report with 9 Row Groups and 1 Column Group (Months).
Instead of showing duplicate rows on the row groups, SSRS and Excel merge those fields. I would like them unmerged! I would like them to duplicate on my report.
I tried going to the parent group and grouping by every other field. This worked until I added two rows within the group, (which I need).
I guess you could also say that I really want my row groups to look like a table. If there's a better way to do that, I'm all ears!
enter image description here
Is it TYPE field that you need all the lines for?
The bracket to the left (under Row Groups) indicates that you are Grouping on something. Remove the Group Only (but not the rows and columns) so you are not grouping and all lines will be displayed.
I have a CSV file that looks like this. It is in matrix form where cell A1 is empty. I want to visualize this in Tableau like this
a1,a2,a3
a1,1,0.2,0.3
a2,0.3,1,0.5
a3,0.6,0.7,1
How can I build this in tableau to show a matrix?
I tried putting measure name in both the row and column field and measure values in the marks text box but i ended up with diagonal values which isn't what i want.
First structure your data in the form of a table.
A well structured CSV file for Tableau (and most tools) has a single header row that labels each column (so skipping the first cell in the header row is a problem). Then each data row that follows contains only values in each field separated by columns (so there should be no leading row labels)
Order is not significant in a relational table. The rows in a table form a set, not a matrix.
So your CSV should look something closer to
field_name_1,field_name_2,field_name_3
1,0.2,0.3
0.3,1,0.5
0.6,0.7,1
Normally, the prime use of Tableau is display an aggregated summary of the data, not to display each individual data row. So you can put measure_names on columns and measure_values on the text or label shelf to get a summary of each measure (by default a sum)
If all you want to do is to view the underlying data rows in a table for diagnostics, the easiest way is to use the view data button or menu command.
If you want to build a visualization that displays all the data (without summarizing it) in a table, you have two ways to go. The simplest is if you have a unique primary key in your data, you can place it on the row shelf to get a row in your viz for each row in your data.
If your data rows do not have a primary key, you can turn off aggregate measures from the Analysis menu, but then you'll see multiple values in each table cell. Then to get a row in your viz for each row in your data, put the calculation index() on the rows shelf and change it to discrete.
