I'd like to create a combination bar/line chart and combine two data sets. I'd like the columns to be months and the rows to be the aggregate values within those months. However, I'd like one of the data sets to display as a bar chart and the other data set to display as a line chart. It should look like this:
I have the following data sets:
data_set1 = [{'value':10,'date':2016-01-01},{'value':15,'date':2016-01-02},{'value':5,'date':2016-01-03},{'value':10,'date':2016-01-04},{'value':120,'date':2016-02-01}]
data_set2 = [{'value':100,'date':2016-01-01},{'value':200,'date':2016-02-01}]
I've been able to create the bar chart (see below):
However when I try to add the values from the second data set by also adding it to the columns section, I get the following error:
"In order to use fields from dataset 2, a relationship needs to be created with dataset 1. Select Data > Edit Relationships to open the Relationships dialog box."
I tried to create a relationship between these two data sets by the following process:
Set the Primary Data Source as data_set2, since that is the smaller dataset.
Selected Custom to create a custom relationship
Selected Add and set both the 'Primary Data Source Field' and the 'Secondary Data Source Field' as Date
However,
When defining the relationship between two date type fields, try selecting the level of aggregation for the date fields, such as Month(Close_Date) in source 1 maps to Month(Date) in source 2. In effect, every value in those fields is first truncated to the beginning of the period (month in this case) before comparisons are made.

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'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.
I am attempting to join two datasets in to one tablix for a report. The second dataset requires a personID from the first dataset as its parameter.
If i preview this report only the first dataset is shown. but for my final result what i would like to happen is for each row of a student there is a rowgrouping (?) of that one students modules with their month to month attendance. Can this be done in report builder?
The best practice here is to do the join within one dataset (i.e. joining in SQL)
But in cases that you need data from two separate cubes(SSAS) the only way is the following:
Select the main dataset for the Tablix
Use the lookup function to lookup values from the second dataset like this:
=Lookup(Fields!ProductID.Value, Fields!ID.Value, Fields!Name.Value, "Product")
Note: The granularity of the second dataset must match the first one.
We had a similar issue and that can be resolved this way.
First of All, ensure the first data set's query and second data set's query are working fine by executing separately on the Database client tool such as Datastudio.
Build two data sets on SSRS tool with the respective queries and make sure both the data sets have same key column (personID).
On the SSRS report design, create a table from tool box and add the required columns from the first data set along with the matching key column(personID). Add a new column and use look up function to get the required column from the other data set against the same key column (personID).
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.
I'm trying to create a report that will contain two pie charts. I get the data for the report from SQL.
Currently, I created a dataset for the first chart which holds records with the following fields: Import ID, Date, Status. This dataset contains duplicate records.
For the second chart, I need the same data I have in the first dataset, only without duplications and aggregated differently.
I realize that I can create another dataset that will get the distinct values from the SQL database, but I was wondering if there was a way to use the built-in filtering functionality to filter out the dataset I already have to return only distinct values (based on ID field).
Looking at the options in the following filtering dialog, I see no obvious way to do this:
If ID is not unique and your 1st query looks like this:
select ImportID, Date, Status
from YourTableSource
WHERE YourConditions
Then you probably should use for your 2nd query form like this:
select DISTINCT ImportID, Status
from YourTableSource
WHERE YourConditions
If changing the query is not an option ,then you may create the Group in ssrs with invisible DETAIL pane and place the ID and Status fiels in int Group pane
