Do we know under which circumstances ax.dtick comes through as NaN here?

It could simply be triggered for example using gl3d_ibm-plot by panning the graph to outside.
I am wondering now that we may need to replace the condition checks in few other places there too? Noting that isNumeric(NaN)returns false; it skips the adjustment blocks starting with if(!isNumeric(...

Hmm. I can't replicate. Can you take a screenshot of

gd._fullLayout.scene.camera.eye

in the console once after that error appears.

I'm actually thinking the opposite: we shouldn't be calling Axes.autoTicks in the first place whenever ditck===NaN. But first, I'll like to know how this happens.

Agreed. For one thing, dtick=1 would draw 1000 ticks on date or otherwise large-range axes which would bog things down and look ugly. What's roughDTick when we get NaN here, and why?

And this is another example example now without date and logs.

Right, this is consistent with what I was thinking: we get those Uncaught ax.dtick error: NaN errors in the console in situations where ticks can't be seen.


// TODO: this is from log axis histograms with autorange off
if(!isNumeric(ax.dtick) && typeof ax.dtick !== 'string') {
var olddtick = ax.dtick;
