Single Date Slicer for Multiple Dates on Visual
Hello!
I have one table that contains 9 columns, 7 of which are dates. They are dates of an enrolment process. I need to create a visual (bar chart) that shows the count of the dates for each column for a definied period. I want to filter the visual using one date slicer.
This is the table:
The visual I want to create needs to look something like the below:
What is the best method for inserting one date slicer to filter all the results? For example, I may want to see the activity of just one week in a month, or the last 3 months, 6 months etc.
Thank you!
Anonymous this is what you need to do, which will take care of everything.
Unpivot your table, in query editor, select your school column and right click, and select upivot other columns
It will add two column, one attribute which will be your category and other column value which will be your dates
Apply the changes, add calendar dimension in your model (many blog posts are there).
On bar chart, use date/month/year on x-axis from calendar table, legend will be your attribute and value will be count of rows from your table.
Now you can slicer and dice the data by date or by category.

Thanks very much! This seems to be doing the trick!
I do have an error message for two of the columns though:
DataSource.Error: Microsoft SQL: The type of column "txtWithdrawnDate" conflicts with the type of other columns specified in the UNPIVOT list.
Details:
DataSourceKind=SQL
DataSourcePath=xxx
Message=The type of column "txtWithdrawnDate" conflicts with the type of other columns specified in the UNPIVOT list.
Number=8167
Class=16I have checked that the column type is Date/Time which it is. Do you know how I could solve this?
Many thanks, much appreciated!

Hi,
A good way to do this, would be to remodel your data.
Try modelling your date columns to a single data column.
Example:
ID Date DateType 123 08/08/12 Leaving Date 123 09/08/12 Registered Date 123 10/08/12 Enquire Date This way you'll be able to do a (Distinct)Count on ID, use DateType as Legend and Date as Axis.
Let me know if you need any more help
