I have a dimension which is simply a list of user groups such as the below:
User Type
Type A
Type B
Type C
I am currently visualising these as an individual pie for each user type with the numerical value shown in the middle which is their answer to a question from another measure. However, I'd like to create a fourth type which is 'All users' so that I have four pies showing at once: All Users, Type A, Type B and Type C.
Is this possible? Would it be a calculated field? I have tried groups but can't get it to work.
Any help much appreciated!
Assuming for the moment that you have User Type on the Columns shelf, you can simply choose Totals->Show Row Grand Totals from the Analysis menu.
An alternate approach is to display two worksheets on the same dashboard. To do that, simply duplicate your worksheet. Remove User Type from the view in the new worksheet. And then place both views next to each other on a dashboard, possibly in a layout container to keep them lined up nicely. Format a bit to remove the titles and outside borders and they can look like one unit.
Remember what a dimension does. It partitions the data rows according to the value of the dimension field, assigning each data row to exactly one partition - exactly like a Group By clause does in SQL. So a data record can’t be associated with more than one member of a dimension. Totals behave differently, which is why they address your use case.

I am creating an interactive 'calculator' using tableau. I have a series of dataframes that I have crossed with one another, such that the resulting dataframe is every possible combination between the tables, and every row is unique.
Each column is its own worksheet as a table. Each table in the dashboard is a pane. So, here we have a series of tables with selectable units of measurement, and the final pane on the dashboard should filter to the cell for its respective column, on the unique row of the dataset that the user has selected and 'filtered out'.
I'm having some issues getting this to work and not sure why.
The closest I can think to solving this would be 'Cascading Filters.' Here are a couple resources:
General Use
In dashboard action-filter form
The critical piece, however, is that the filters must be selected in a specific order - therefore making them 'cascading.' This may differ from your presumed concept of clicking/filtering in any order on the worksheets to then arrive to a final answer. I do think that this may be a limitation of Tableau - I don't think that a 'many to many' type of relationship can be set up within Action Filters.
I have a calculation and it outputs multiple values. Then I am creating a table on those values. For example, in below data my formula is
if data is 1 then calculation is `one`
if data is 2 then calculation is `two`
if data is 3 then calculation is `three`
as three doesn't really appear in the output, when I create a table, three is not displayed. Is there any way to display it?
I tried table layout >> show empty rows and columns and it didn't work
data calculation
1 one
2 two
Tableau discovers the possible values for a dimension field dynamically from the query results.
If ‘three’ does not appear in your data, then how do you expect Tableau to know to make a column header for that non existent, but potential, value? It can’t read your mind.
This situation does occur often though - perhaps you want row or column headers to remain stable, even when you change filters in a way that causes some to no longer appear in the query results.
There are a few ways you can force Tableau to pad ** or **complete a domain:
one solution is to pad your data to make sure each value for your dimension field appears in at least one data row.
You can often do this easily by using a union to append some extra rows to your original data. You can often add padding rows that don’t impact any results by leaving all your Measure columns null since nulls are ignored by aggregation functions
Another common solution that is a bit more effort is to make what is known as scaffolding data source that is not much more than a list of your dimension members. You can then use that data source as a primary data source with data blending, making your original data source secondary.
There are two situations where Tableau can detect the absence of data and leave space for it in the visualization automatically
for numeric types, you can create a bin field that will automatically pad for missing bins
similarly, date fields can show missing values because, like bins, Tableau can tell when a month doesn’t appear in the data and leave room for it in the view
I have 3 dimensions in the following hierarchy:
BigC
L SmallC
L Brand
(Having 200 combinations)
I am also creating a calculation using a parameter and multiple case statements.
For eg: CASE WHEN parameter=Brand1 THEN Brand1_field - Impact% END
Now I want my parameter to have only the relevant brand values populated for Big C and Small C rather than all the values. Is it possible?
If this is not possible then can I create a calculated field with a column selection?
If i have understood your question properly, I was able to achieve this using Context filter and Filter by Relevant Values.
Drop both Big Company and Small Company dimensions into Filter Card.
Apply Context Filter for Big Company and "Use only relevant values" for Small Company filter.
So as when you select values for Big Company only the related values of small company will be displayed and so the brands.

I'm using Tableau Desktop v9.0. I have data that looks like this:
code,items
02050252,7
03040620,19
03060423,3
I want to create a bar chart of the items grouped by the first two characters of the code field.
So effectively a chart that shows this underlying data:
new_code,items
02,7
03,22
Is it possible to do this within Tableau? Or do I need to group the data manually myself first?
You can definitely do this within Tableau.
Make sure that your code column is a string. If it's not, right click on it in the dimensions section and choose Change Data Type.
Then, create a calculated field (Analysis -> Create Calculated Field) and enter the expression LEFT([Code], 2), which will take the first two characters of the code field.
Drag your new_code field to the Rows shelf and Items to the Columns shelf and voila, you have your desired data. You can of course change the type of the chart, make it a table, etc. from here.
Is it possible to have add a row to an SSRS 2008 Matrix that spans all of the matrix's columns?
This crude diagram shows roughly what I'm looking for:
The basic idea is that each line item is a person, and each column is a field in a form for that person. The fields themselves are dynamic (and implemented as column groups on the matrix). Additional column groups are included to append non-dynamic form fields, like the time the record was entered and who entered it. Under each person's record is a comments field, which should span all of the form fields above it.
At the moment I have the matrix embedded in another tablix, with the name and fields in the matrix and the comments in the parent tablix. This works for the data (each instance of the matrix ends up being one row), but the header repeats too often (once per person) because it's attached to the matrix. The only thought I have as to how to fix this is to create another matrix in the parent tablix with the same grouping and use it to display the headers... But this will require quite a lot of manual synchronization to keep the two matrices the same.
Edit: The key problem here is making the second row span multiple column groups.
Here's what you can do:
Select the column grouping you want to add above and right click and select
Add Group... Parent Group...
Group the column by something that will not aggregate the data. You'll have to select a field from your dataset to group by so that it creates an overlapping column grouping.
Check the Add group header box
You should now see something similar to this:
Now you just need to move the Value1 field and it's header over under the new column to the right beyond the matrix dividers. Once that's done, simply delete the ungrouped column where you just copied Value1 from and be sure to select Delete columns only checkbox.
Your finished product should look like this:
It is possible - And the above answers are partial answers leaving out one key step: Merging the cells of the child row.
First, right click on your grouped row, then select Insert Row -> Inside Group - Below and you will get two rows with the cells aligning on the columns
Second, ctrl click all the cells in your new row (ie row without the data) then right click on one of the highlighted cells, and then select Merge Cells.
Now you have the table you like. To add a value to the new row: first right click your new (multi column) cell,select Create Placeholder, and then add the dataset item you desire to the placeholder.
[Edit]
After several attempts, I'm going to say this isn't possible in SSRS. The best I could come up with is a group footer that spans columns 1,2, and 3, but not the User column.
[Original Response]
I recently did something similar to this.
First, what tool are you using to create SSRS reports? (I used SQL Server Business Intelligence Development Studio)
You'll want to create a row group (grouped on Person)
Append a row to your table in "Design" view (Right click, "Insert Row --> Inside Group - Below").
Add an expression to the row that pulls the value for your "Comment" column (=Fields!Comment.Value).
Let me know if that helps...
Try adding in you column group "header" with a grouping expression of (1=1). Then a detail field will need to be defined. If you define the other group with correct data then the "header" will stretch across all details columns. You may need to merger depending on other options.
The easiest way to do this is to create a Tablix with only one column, and your row grouping.
Then, you create two rows inside this group.
In the first row inside the group, you insert a Matrix, wich you can then subgroup as you prefer.
I just had a similar problem, and this was my solution.
I banged my head against the wall for a lot of time, until i realized the solution to my problem wasn't "making a cell span multiple column groups", but "making a cell split into multiple column groups".
You can accomplish the goal by using a subreport for each person. The subreport will receive the employee id and create the hierarchy for you. Make sure your subreport column widths match the widths of the parent report.
