Main point was getting an overview of the level of fragmentation (big parties lose - small parties gain on average), not the ideology stuff, that was just for reference.
It's mostly a very simple left (SD)/right (Cons) distinction. "Populist centrist" is the term I have used for those with no ideology whatsoever (AFAIK).
The far left parties and Greens + the Christian Right seem to be fairly ideologically consistent, or is that not so?
the PT & Democrats also seem Ideologically very consistent- part of the reason they're very popular- because at least voters know what they stand for!
