Thanks to Vineviz, I downloaded Mapviewer and made the attached gradient maps of the ydna frequencies Nordic countries excluding Iceland and the Faroes.
I based the frequencies in Norway on the regional data from "Geographical heterogeneity of Y-chromosomal lineages in Norway". I included Bergen in the Western Norwegian region and Oslo in the Eastern Norwegian region. I also split the Northern Norwegian region into Finnmark and the rest because of the higher level of N3 in Finnmark (according to the article) assuming the relative frequency of all other haplogroups remained constant.
The data for Sweden are from "Y-chromosome diversity in Sweden A long-time perspective", the Finns are from "Regional differences among the Finns: A Y-chromosomal perspective". I have split Saami in two Swedish Saami and Finnish Saami (Data from "The Western and Eastern Roots of the Saamithe Story of Genetic Outliers Told by Mitochondrial DNA and Y Chromosomes" as well as Karlsson 2006 for the Swedish saami).
The data for the Danes comes from a whole range of smaller studies. The level of I1a vs other I is difficult to determine for the Danes.
The samplesizes from Sweden are all very low, and it is probably best to view these maps with a good portion of healthy skepticism.
