Filter by column in underlying data

[td48260]

I have a table called Apps with 3 columns:

ID (Prmary Key)

Year

Type

I would like to create a column chart that groups by year, displays a count, and has filters for Type and Year. The SQL query would look something like this:

SELECT Year, COUNT(*)

FROM Apps

WHERE Year IN ([Year filter selected values])

AND Type IN (Type filter selected values])

GROUP BY Year

The Year filter is a simple drag and drop, but how would the Type filter be implemented? Type can't be in the final data set because it would throw off the count. But if Type is not in the final data set, then how can a page filter be created for it?

Thanks,

Tim

@td48260 yes this functionality is out of the box, seems like you are overcomplicating it.

Simple question, if you have years on rows, count rows on value, and slicer by type A what do you get? You should get the correct result.

Maybe I'm missing here something obvious.

Yes, I was overcomplicating it! Once I removed the GROUP BY operation and added a Measure COUNTROWS(Table), it works.

Thanks for your patience and help!

Sorry, I didn't explain it well.

ID	Year	Type
1	2014	A
2	2015	B
3	2015	C
4	2016	A
5	2016	B
6	2016	C

I want a column chart where the Axis column is Year and the Values column is a count of the rows. There should be filters or slicers for Year and Type. In the example above, if all Years and all Types were selected the chart should reflect this data:

Year   Value (count)

2014  1

2015  2

2016  3

If only A is checked in the filter/slicer, then this should be the data:

Year   Value (count)

2014  1

2016  1

The order of operations should be

1. Filter table rows by Year and Type filter/slicer values

2. Group the results by Year

3. Calculate Count for each Year

I tried creating measures for 

COUNTROWS(Table)

and 

calculate(count([value]),table[year]== selectedvalue(table[year]) && table[Type] == selectedvalue(table[type])

In both cases I got syntax errors which I've been unable to resolve.

Thanks for your help.

@td48260 not sure what you mean using type on the slicer will throw the count off

just use type and year as a slicer and a simple measure

Count = COUNTROWS ( Table )

or maybe I didn't understand your question, explain it with sample data if that is the case.
