I am new to using Tableau.I want to count the number of times each genre appears in the data set.
In the data set(image attached), I have several genres for one show. I want to count the number of each genre in the data set and display it in Tableau
If you have access to database, then take the dump of data in a excel.
Split the data by , and then create a individual column for every word in the genre column.
Now take the excel as source to tableau, In tableau pivot the splitted columns of Genre.
Go to sheet in tableau, Place the pivot field values in rows and count of pivot field values as measures.
You should be able to see the desired result.
This can be done by an alternative method if you know the distinct list of all genre.
what you need to do is to create a separate calculative field for each Genre using
if contains(Genre,'action') then 1 else 0 end
and then use the Sum of these field as the count of Series per genre.
I know this is a hideous task but, it can be done if you do not have any other option.

I used an Apriori algorithm to view the frequent relationships in the dataset and I want to do a dashboard to better visualize this data but I don't know how to do this filter.
This is the bar chart that I created to show the support (amount of times something happend) and the confidence (probability of B happening given A) of these associations:
Apriori Chart
Next to it on the dashboard, I'll have a table with the full dataset used in this Apriori analysis where I have more information such as ID, Income, Hours Worked, etc:
Table from different data source
How can I create this relationship? The two data sources don't have a column in common that I can use for that.
I would need some way to:
Split the values in the antecedents columns by comma and filter only those columns with value equal to 1 in the other dataset
**Dataset A**
'Age Range <=30, Joblevel 1, Maritalstatus Single'
->
'Age Range <=30'
'Joblevel 1'
'Maritalstatus Single'
**Dataset B**
'Age Range <=30' == 1
'Joblevel 1' == 1
'Maritalstatus Single' == 1
Clicking this would filter the table next to it
Is there any way I can do this in Tableau?
You can download the tbwx i used in this example here https://community.tableau.com/servlet/JiveServlet/download/1083124-384949/Apriori.twbx
Thanks in advance for the help!
I am not able to check your twbx on the machine I'm using but I think you should be able to do this. The fields in the 2 data sources need to match so manipulate the data sources the make this happen.
For data source 1 there's a function SPLIT which will mean you are able to split the comma separated string to 3 fields.
Putting those 3 fields to the Detail shelf of your bar chart (or even Rows and hiding the header) will mean you can use them in an action filter.
Your second data source is a cross tab - post pivot. You should be able to pivot this data source. Highlight the measures and pivot them. This will give you the field Pivot Field Names and Pivot Field Values.
You only want to keep those with a value of 1 so create a calculated field
[Lookup1]: IF [Pivot Field Values] = 1 THEN [Pivot Field Names] END
Duplicate this field twice so you have Lookup1, Lookup2 and Lookup 3.
Then you should be able to action filter the table.
In the action filter set it up so SplitField1 = Lookup1, SplitField2 = Lookup2, etc.
Fingers crossed this works, I haven't been able to test so I am pulling it out of my head.
I am trying to filter a table visualization of all of my data by looking to see if a Study Number contains Activity A. If a Study Number contains Activity A then I want to filter for all rows containing those Study Numbers even if the Activity is not A. See mock data below. In my real data set I have ~55,000 rows.
I have created a calculated to return Study Numbers if Activity= A but I am not sure where to go from there. Thanks for any help.
If(UniqueConcatenate([Activity]) OVER ([Study Number])~="A","Y","N")
Will give you this resulting column that you can then filter on (or you can use the formula as a Data Limiting Expression:
I want to add rows to a Tableau text table without making the row a subset of the previous row. Using the example below, I want values for teams and status to display on separate rows rather than status appearing as a subset of team. I also want to add a team filter so that if I filter on team blue, values for green row are zero and status values update . Is this possible? I tried creating separate worksheets but keeping things aligned is problematic.
Example Data:
Desired text table:
What I don't want:
Select both the fields(team, status) simultaneously then right click and go to Transform > Pivot.
Then 2 Dimensions will be created. Drag the Pivot Field Values on to Rows section
and Year on to Columns section and keep Year in Discrete format.
Then drag Number of Records on to value field section.
Before Pivot:
After Pivot and final viz:
Either I am the first person to ever need to display percentages in Tableau or I do not know what to search for! I highly suspect it is the latter...
I believe what I am attempting to ask is how to make a calculated non-aggregated field by dividing by an aggregated number. Although I would prefer just to be able to display the percentages instead of a whole number.
This is how I would do it in Excel:
The data that already exists is Column A and B. In Tableau these would be non-aggregated. What I need to do in Tableau is to generate what is column C (also non-aggregated) because it does not exist in my data. In excel, all I did to get the aggregate number (total) of column B was:
sum(B1:B4)
And for the column C:
=B1/$B$5
But I can't seem to do this at all in Tableau. When I try to use the same syntax, I get an error message: "Cannot mix aggregate and non-aggregate arguments with this function."
Instead of having a calculated field, you can use a Quick Table Calculation on the column.
Right-click the pill of your data > Quick Table Calculation > Percent of Total. This will show the percentages instead. If you want to keep both, just duplicate column b first and then add the table calculation to the new column.
I have a query with 3 parameters that a user should be able to define:
AND (ORION_SCHED.TRIP.DATE_TIME = '09/11/2012')
AND (ORION.CUST.COUNTRY = 'BE')
AND (ORION_SCHED.TRIP.ID_SHIFT ='1')
DATE_TIME should be a datepicker
COUNTRY dropdown with defined values
ID_SHIFT dropdown with defined values
I guess this isn't an issue?
The result of this query will return the dataset
My actual question: I want the result to be presented in this way
So always 3 blocks of data next to each other, the data of every block is the result of the query filtered down on the column TRUCK_ID (a sub-select of the returned dataset)
The empty cells per block are a nice to have, these are non-unique values per TRUCK_ID that I don't wish to be repeated on every line, but like I said a nice to have.
I would add a new column to the query that returned 1,2 or 3 (for each different TRUCK_ID. Then I would use 3 Tablix (one per column on your report) and filter the data by the new column you added on the query.
Then you just group on the TruckID on each tablix and play around with the format. It should work.
