Creating a measure that scales the sum to 100%

[GoingIncognito]

I've table "Basket constitution" that has the weights of differend indices. Weight is an integer. Now, how do I create a measure that scales to 100% for any subset of these weights? E.g. a basket with weights 3+3+5 and 6+10+15 would both scale to 100%? I'm guessing I'd use the function allselected?

Hi @GoingIncognito ,

I'm not sure if i understand you correctly, are you meaning 3,3,5 belong to same category and 6,10,15 belong to another same category and you want to calculate the percentage about each value for each category, like 3/(3+3+5)?

Best Regards,

Maybe I figured this finally out?
Is this correct:

_weight =

var _sum= SUM('Basket constitution'[WEIGHT])

var _whole= CALCULATE( SUM('Basket constitution'[WEIGHT]), ALLSELECTED(table2*) )

return

DIVIDE( _sum, _whole)

*=table2 is the table that provides the row values for the graph I'm trying to build

And now if I need to use table3 instead of table2 in my graph, how do I incorporate treatas() ?
