Bottom N based on Condition
Hi!
I am very new to Power BI and this is my first post here on the Power BI forums. I have previously found quite a few gems on here that I applied to my work. I am hoping I might get an answer to my problem below:
I am working with a student academic performance dataset. I am required to create a list of top 10 best performing students as well as a list of 10 at-risk (worst performing) students. This is easily done using Filters. Where I am facing an issue is I need to add a condition to the list of 10 at-risk students. If the total mark is below 50, then I show them on the list, otherwise I leave the list empty. My pseudocode is something like this,
If 'GradingData'[Total] < 50, then show in table else leave table empty.
How can I go about achieving this? Thank you in advance!
Hi AyeshaA10 ,
You can use filters in your case to showcase your results:
Hope this helps, please let me know if this doesnot work out.
Create a measure like
Is At Risk = VAR CurrentStudent = SELECTEDVALUE ( 'Grading Data'[Student ID] ) VAR AtRiskStudents = TOPN ( 10, ALL ( 'Grading Data' ), 'Grading Data'[Total], ASC ) VAR VisibleAtRiskStudents = SELECTCOLUMNS ( FILTER ( AtRiskStudents, 'Grading Data'[Total] < 50 ), 'Grading Data'[Student ID] ) VAR Result = IF ( CurrentStudent IN VisibleAtRiskStudents, 1 ) RETURN Resultand add this as a visual level filter to only show when the value is 1
Thank you very much for your help! I've saved this DAX measure. I think this is going to come in handy later.
