Histogram mistery

[employe4_2]

HI

I'm working on an histogram showing the proportion of "cakes" depending of their weight.

i got also a KPI getting me the exact quantity and the scrap %.

Si when i select an interval of weight my scrap rate and quantity change

but as soon as i change in my histogram my weight for an other variable for exemple " Temperature of oven", the selection doesnt impact my quantity and scrap rate ....!!

why is that? Is this a question of "main" variable" or something ? should it chnage like with the weight? is it suppose to change ?

any idea ?

It sounds like an issue with the underlying data model to me

HI,

How are your tables related ?  Can you show us the screenshot of the data model viewer with the relevant fields in view ?
