Dynamic Column selection based on Slicer selection

SreejithR — Fri, 25 Sep 2020 18:58:21 GMT

Hi All,
I am new to power BI and DAX and looking for solution for below issue.
I want to generate a runtime dynamic column based on slicer selection
Sample data as below.

Opportunity_Key	Quarter	Month	Rainmaker	Rainmaker_Qrtr	Rainmaker_Month	TCV
100	Q1	Apr	Donald	Donald	Donald	250000
172	Q1	May	John	Sam	Sunny	500000
183	Q1	May	John	Sam	Sunny	250000
186	Q1	May	John	Sam	Sunny	2200000
546	Q2	Jun	Steve	Steve	Steve	2400000
560	Q2	Jul	Mary	Steve	Mark	200000

And the use case as below,

If user has done any slection on Quarter Slicer, column "Rainmaker_Quarter" to be considered for the dynamic column
Else if user has done a slection on Month Slicer, column "Rainmaker_Month" to be considered for the dynamic column
Else column "Rainmaker" to be considered for the dynamic column

I am able to write it in a calculated measure like below

MeasureRainmaker = IF(ISFILTERED(pre_sls_tbl[Month]),pre_sls_tbl[Rainmaker_Month],IF(ISFILTERED(pre_sls_tbl[Quarter]),pre_sls_tbl[Rainmaker_Quarter],pre_sls_tbl[Rainmaker]))

But it doesnt look useful for me as I can't put the measure in the X-axis of a bar chart.
Basically my bar chart to show various rainmakers on X axis and curresponding TCV on Y axis depends on the slicer selection.
Can anyone please guide me?

thanks

SreejithR , You can create a calculated column with slicer values. For that, you need to take the help of Dynamic Segmentation.

Refer to how it works on video or these blogs: https://youtu.be/CuczXPj0N-k

Can you share sample output ?

Hi amitchandak,

Thank you for your kind reply.

I have gone through the links you have provided, unfortunately still unclear on how to achieve this with Bins and Groups.

Coud you please help elaborating it little more, or can you please share some steps I should perform in power bi desktop?

thanks

Hi All,

Any help/guidance in this?

Basically I am trying to show my Visual1 barchart X axis dynamically based on the period selection in visual2. If quarter selected in visual2, show values from column Rainmaker_Quarter in visual1 x-axis, if month selected, show values from Rainmaker_Month column else Rainmaker column. The use case looks to be pretty straight forward and easily achievble in tableau. I am new to Power BI and struggling to achieve this. Can anyone please guide?

Thank you
