Calculating measure with RELATED at get wrong answer

[Jannis68]

Hi,

I have a caluclated measure (Average Score) which is a function of two other measures (TotalScore = Sum(Table[Score]) and SCount = Count(Table[Score]). To plot the average score in a circle, using a scatter diagram, I am trying to calculate the x and y using sin and cos, respectively, and radians based on categories, where the angle should be looked-up using related-table. In MS Excel this would have been straightforward, but in Power BI the result seems to be multiplied by the product of 'the number of attributes in a category' times 'the number of respondents'. What am I doing wrong here?

Hmm, can you supply some sample data and more information on your calculations? I have some Quick Measures submitted to the gallery for converting Catesian coordinates to Polar, (and the reverse) not sure if those would be of any assistance:
