You're right, the charts don't show that. But the charts don't tell the actual story. Which is that all centrist parties have shifted right in their policy positions and rhetoric. The charts only show power shifts between parties, but ignore shifts within parties. There's a lot of centrist parties that were rooted in Christian values for example, that were reasonable on e.g. refugee issues in the 20th century (which were much more significant than today, by the way), that now want to amend laws, retract long-standing treaties, create walls and border fences, disallow schooling/work/status for those refugees who do get welcomed so as to send them right back asap in god knows when Syria recovers from being a failed state, paired with hints of xenophobic rhetoric akin to a far right party. Yet they're still deemed centrist parties, and would not show it on the chart. And that is precisely because the far right is on the rise, and the rest of the political spectrum is adjusting and compromising their stance, so as not to lose votes. That's a very clear shift to the right. Like take the Netherlands, it shows a drop in the right-wing PVV's size since 2010 (forget for a moment that the party's currently leading in the polls). You'd think, alright no shift to the far right here at all. What it doesn't tell you is that the current biggest party (a non far right wing, right wing party) has shifted much more to the right. Like recently we saw it's 2nd in command claim refugees were visiting the Netherlands to get plastic surgery, breasts corrections, face lifts etc... I mean this guy is just a ridiculous demagogue, instilling fear into the Dutch population that Syrian refugees aren't actually running away from a gruesome war, but are merely looking to exploit our medical system to get plastic surgery, it's insane. If you'd have set this about jews during the holocaust there'd be no discussion, you'd recognised as a clear far-right fascist. And this is the biggest party's 2nd in line, straight out the playbook of a far right-wing demagogue. Now this party isn't far-right for all intents and purposes, but it has very much shifted towards it on various policy positions and rhetoric, as have many centrist and right wing parties. And none of that shows up in the charts.
