Yes. A transform scales the whole drawing coordinate system, so the stroke width is scaled as well. > Since this would seem to be a common task, is there a recommended way to > keep linewidth = 1 (and likewise for data-point circles) or would I be > better off just doing the transformations "manually" beforehand? You can either a) compensate the linewidth by the inverse of the scale, b) use a linewidth of 0, which will draw a 1-pixel wide line regardless of scale. However, this latter approach is not such a good idea if the view can be printed, because 1-pixel on a high resolution printer is extremely fine, or c) if your graph data is in the form of a path, you can scale the path by the transform rather than scale the view, then it will have the stroke width you give it.
