Presumably X, Y have the same scales - so unless you want to treat the different directions differently, make sure not not apply any normalization. As that would distort the grid. Your Value column on the order hand, might be on a very different scale from ...

With the information you provide, I suggest you can use both and test based upon a metric like Siluhette Score or Davis Bouldin index to measure the quality of your clusters when using either of both preprocessing techniques. In this way, you will have an objective metric to compare between the two preprocessing techniques and keep the one that maximizes the ...
