They do not see this rise.
Finland also has a markedly higher murder rate to start with (for whatever reason), and it absolutely shows a distinct rise in the last few years – much more so than Sweden in fact.
Norway is indeed more stable. However, Norway also accepted significant number of migration. Although it's hard to tell how much exactly because of different definitions, it seems roughly half as much as Sweden (adjusted for population), which is less but not nothing.
And in a quick check Finland has seen even less migration than Norway.
So you will need to explain why Norway sees no rise in spite of migration, and Finland sees a rise in spite of less migration.
And sure, I'm willing to accept that migration is a factor in Sweden. Although I can't tell you how exactly since I'm not familiar enough with the nuances in Sweden. But this "argumentum ad charts" you're making that migration somehow automatically leads to crime is complete bollocks.
Just minutes ago in another comment you yourself posted a link which clearly and markedly shows that Finland has seen a marked and steep rise in the last few years: https://news.ycombinator.com/item?id=38339299
And my main point was that "gun violence" showing near zero for some countries shouldn't absolutely not be taken as "near zero crime" or "near zero homicide".

But reliable figures are hard to come by, partly because if scientists, even accidentally, find that, e.g., most rapes are committed by immigrants, they get prosecuted (eventually the charges were dropped, because they couldn't prove "bad intentions", negligence, or carelessness) [1,2,3,4].
The other reason is that, though Sweden used to collect data about criminal's ethnic background, they stopped I think in 2005 [5]. Though it seems they've resumed - in searching for sources for this post, I found https://emilkirkegaard.dk/en/2021/11/sweden-finally-publishe...

Looking at [1], murder rate in Slovakia is comparable, and Hungary only slightly lower. Sweden isn't even near the top murder rate in the EU, and a number of other countries which accepted a large number of refugees have lower murder rates than Sweden.
