PPC got 1.6%. Not sure that qualifies as a "vast majority".
Also keep in mind that minor parties usually perform significantly worse on election day than how they poll, because of all the voters who like saying they're going to vote for the minor party, a significant portion of them decide at the last minute not to piss their votes away on election day. This is a well known trend in multi-party elections.
Edit: About 100 polls counting the PPC here in the month leading up to the election, and all but 11 of them overestimated the PPC, sometimes by up to four points.

Read again what I wrote. The PPC accounted of the vast majority of the "other parties" vote. Besides "the Independents" no other minor fringe party got more than 0.1% of the vote. Most of them got between 0.01 and 0.05%.
You can compare it with the last election in 2019.

"Other parties" including the PPC got 2.4% of the vote. The PPC accounted for the vast majority of it.

Notice the polling vs actual election performance from the 2019 election. All the major parties with the exception of the BQ did worse than what their polling predicted. The PPC polled at 2.6% average the day before the election, but only got 1.6% of the actual vote - underperforming all but one of the final polls (which was within 0.1% of the actual result).

1.6% is 2/3rds of 2.4%. That's a majority, but a vast majority.
If we extrapolate that share to the OP's chart, that would mean the PPC is polling at 4.6% in this poll. They polled higher than that a few times leading up to the 2019 election, and still finished with zero seats.
