Violin Plot Tool Issues When "Grouping By"

5 - Atom

Hey all - been having a really simple issue with Alteryx.


I'm trying to eventually create a series of violin plots to compare the distribution of two data sheets.  The violin plots work just fine if I simply put in "Sales" but if I try to put in "Sales" AND group by any metric I receive the following errors:


Error: Violin Plot (3): Violin Plot: Error in quantile.default(data, 0.25) :
Error: Violin Plot (3): Violin Plot: Execution halted
Error: Violin Plot (3): Violin Plot: The R.exe exit code (1) indicated an error.
End: Designer x64: Finished running in 3.9 seconds with 3 errors


Any ideas what could be causing those errors?

Hi @altericks 


This error is generally due to Null values in your data.


Have you checked if there's any null value being generated when you group by this metric?


If there is, you need to clean this data or imputate values (which is actually the most recommended solution).
