implicit normalization behavior in weightedSum

[dominikandreas]

I would like to have a weighted sum without any normalization, but that doesn't seem to be possible.

As can be seen here, normalization is still applied to the weighted sum range at the end:

parasol-es/src/api/weightedSum.js

Lines 48 to 55 in 31fcdae

	// normalize all values against total weight and assign values
	const extents = arr.extents(row_totals);
	data.forEach((d, i) => {
	config.data[i]['weighted sum'] = (
	(d.score - extents[0]) /
	(extents[1] - extents[0])
	).toString();
	});

Whereas the norm parameter only controls normalization of the input data normalization.

In my opinion the default behavior should be to normalize neither, because it isn't something that I as a user would expect when I call a "weightedSum" operation. At the very least there should be an option to disable both forms of normalization

Edit: Just noticed there's the additional "score" property that isn't normalized. I guess that does what I want, but still think this behavior is strange

Thanks for your request! It's been awhile since I've worked on this project and I don't have much time to maintain it at this point. However, if you'd like to submit a quick pull request, I'd be happy to review it and get something merged.

Hopefully the "score" property has been working for you in the meantime!
