This is arguably a "bug" that the dash descriptors aren't being scaled along with the line width. However, I'm loathe to "fix" it as it's been this way a long time, and all backends are at least consistent with one another in this behavior. Note, however, that inkscape, and I suspect other vector graphics tools, don't behave like matplotlib -- the dashes are scaled with the line width -- even though the underlying format, in this case SVG, doesn't behave that way.
As a workaround, you can explicitly set the dash sequence, e.g.: plot([1,2,3], lw=6, dashes=(6, 6)) See here: http://matplotlib.sourceforge.net/api/artist_api.html#matplotlib.lines.Line2D.set_dashes Cheers, Mike Robin wrote: > Again, apologies if this is an obvious question but I couldn't find the > answer. > > With a lw=1 dotted (:) line the dots are square and it looks very > nice.
