When you increase the dpi, the canvas gets bigger (inches*dpi equals canvas size in pixels). If you are drawing in pixels, and not scaling, the barbs should look smaller, since they are a smaller proportion of the canvas size. So if this explanation is right, the barbs will look smaller with larger dpi. > Then I also can't figure out what the PS backend is doing. If PS is > hardcoded to 72 DPI, why does passing dpi=72 to savefig() have any effect? ps should be unaffected, but dpi dependent backends will. By setting the dpi to be 72, it should make the *other* backend look like the ps backend and the ps backend should be unaffected.
