Transform Related columns using PowerQuery

[Shippior]

In the current dataset I have I am encountering a problem that I can not wrap my head around.

I have a total of three datasets.

Dataset 1 has Column X containing values that are equal to Column A of Dataset 3. Dataset 2 has column Y  containing values that are equal to Colunmn B of Dataset 3. My goal is to relate Columns R,S,T in Dataset 1 and Columns P, Q, R in Dataset 2 to each other based on the information in Column A/B. However, using relationships in the Model creates a loop that does not work. How can I transform the dataset in PowerQuery such that I can plot Columns R,S,T vs Columns P, Q , R?

MWE of the datasets:

Dataset 1:

X    R S T

ab  2 3 4

xy   4 5 6

Dataset 2:

Y    P Q R

qw 4 2  2

ds  4 5  4

Dataset 3:

A   B

ab qw

xy ds

I solved this by combining Query Dataset 3 with Dataset 2 and manually exchanging Column Y with column B. You could then append query dataset 1 and dataset 2 to reach a homogeneous dataset.

@Shippior , Not very clear.

But merge dataset 3 and 1 (A- X) and then merge with 2 (Y- B)
