axes range not working. Range is +-1, data is 0->1.6e10

there should be 2 points visible in that plot, but there are none. Comment out the range to see the 3 points

Thanks @28raining - I see 2 points, for you it's just blank? What browser/version/OS are you on? @archmoj what does it look like for you?

ha, you are right! It only doesn't work in Safari.

Safari:

Safari Version 17.3 (19617.2.4.11.8), Intel MacOs 14.3

Ah! Yep, missing for me too in Safari. Even weirder, when I start dragging one of the ends of the axis, very often the points appear, then they disappear again on mouseup, until I get to a range of ~500 then they stay visible.

So feels to me like this is a bug in Safari's SVG rendering engine, some optimization when the total coordinate range on the plot is very large (the off-screen point is translated up 2159999999865 pixels!) that it stops doing when things get more complicated (in this case, while dragging the end of the axis we apply a scale transform to the points).

We could try to work around this bug by restricting the number of pixels we'll try to shift; that should be fine for markers, but we'll have to be careful if we do this for lines, so that they keep the correct angle while shooting off-screen, so we'd need to constrain x and y together in a smart way.
