Based on the discussion for far,
I assume it works like this.
(figsize in inches) * dpi = (size in pixels)
So if you draw a line 72 points long,
which is 1" in figsize units,
then it will display as being dpi pixels in length.
So for PNG, for example, figsize is a kind of
Platonic concept, which we view dimly through
the actual size of our figure.
By the way, I've discovered that browser scaling
of PNGs does not work very well (fuzzy fonts), so
setting both figsize and dpi correctly proves
rather important. In contrast to best practice
for loading speed, you should not set the size
of your IMG element. Or so it seems.
fwiw,
