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. But when I put lw up say to 2 or 3, the dots become rectangular,
which looks a bit odd, particularly at points where the underlying
graph curves sharply compared to the spacing of the dots.
Is there anyway to keep the dots square (ie as lw=2 for both
dimensions) instead of rectangular?
Cheers

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:
